I'm having a problem on layouting my app specially when I images are involve.
In the attached image below, how to create a navigation button like that? It also appears translucent, how to do that?

just looks like a listView, well ... I lie that looks like a horrid webview/html oddity, but in android you would just use a listView for the main view
Or
If the menu items are static and not mutable then a simple frameLayout as parent then a linearLayout for the buttons views

Thanks for the answer. I'll try to use what you said.

not sure I understand, but whatever you're after, if it's just inspiration, there will be many examples just searching google

using xml item or json for dynamic data
I m writed simple example for you :
If you have a limited and not dymanic data, you can use xml item for listview, like this :
Add this your string.xml
Code:
<string-array name="schoolsname">
<item>School 1</item>
<item>School 2</item>
<item>School 3</item>
</string-array>
Add listview to your layout file :
Code:
<ListView
android:id=”@+id/list”
android:layout_width=”fill_parent”
android:layout_height=”wrap_content”
android:entries="@array/schoolsname"
/>
And in your Activity class you just defined your listview, like this :
Code:
public class MainActivity extends Activity implements OnItemClickListener{
ListView list;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
list= (ListView) findViewById(R.id.list);
list.setOnItemClickListener(this);
}
// [B]onItemClick When clicked your list item[/B]
@Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long id) {
Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
Toast.LENGTH_SHORT).show();
}
}
Sorry my english. I m still learning.

WebView - Handle JavaScript Pop Up ?

Hi,
I am new to Android Development. I am making an application with a WebView object. This loads a URL with some elements. However, I cannot get JavaScript PopUp to show up when the button is pressed.
My WebView has JavaScript enabled, but all other properties are disabled.
What is the property to enable WebView popups to show??

I had to do this. Override the onJSAlert() method in the WebChromeClient class:
Code:
public class MyWebChromeClient extends WebChromeClient {
@Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result)
{
final JsResult finalRes = result;
new AlertDialog.Builder(view.getContext())
.setMessage(message)
.setPositiveButton(android.R.string.ok,
new AlertDialog.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which) {
finalRes.confirm();
}
})
.setCancelable(false)
.create()
.show();
return true;
}
}
Then add it to your webview:
Code:
MyWebChromeClient myWebChromeClient = new MyWebChromeClient();
webView.setWebChromeClient(myWebChromeClient);

Thanks. That did work!
One small thing, how do you set a Title for the pop-ups. Currently it shows the url in the Title.

I found a better example that sets the title:

I tried that, but the Title is only displayed when the alert has one button/option. When there are multiple options, the Title shows the URL.

Sorry not sure how to fix that

[Q] Noob working on first solo App (aka: help)

Dear XDA,
I am a noob developer and I am trying to create my first real android application. (outside of Hello World prompts and predetermined tutorial programs) I am looking for a bit of guidance on how to best approach my project idea. What I want to do is create a sort of personal cook book for a friend with a main menu with options that takes you to a submenu with additional options that will take you to content pages that have return home buttons.
Please keep in mind that I am still in the learning process and want to learn. Any tips, comments, or approaches would help me a lot.
I am using eclipse to program currently and heavily relying on resources like http://developer.android.com to do even the simplest things.
Thank you!

Well without getting into much detail i would say that you would need to come up with a data structure to store your recipes in, make some layouts for the screens you want to display. Also try to reuse the Activity that displays the recipe. When you start that Activity you can send an Extra in the Intent to specify which recipe to display. This will make it very easy to add recipes on the fly
From something awesome

Additional to what killersnowman said, I would recommend you to study ListActivity, and also databases, so you can add recipes from app.
Also you may want take a look to shared preferences.
If you have some coding question, feel free to contact me
Cheers From Colombia
D4.

Depends on if you want to be able to add/edit recipes or not. If you're going to add/edit etc., you'll want to do a database. If you just want to display recipes, reading in flat files would probably be easiest.

Probable be best to use strings.XML for the recipes. And for the buttons search for information about onClickListener and intent.

Thanks! Progress Update #1
First off thank you for all of the help so far! So far I have two XML layouts (one for the intro page with a picture, dedication, and button to the main.xml and the main with buttons to different categories inside the application)
This is my first independent code (which I am oh so proud of even if it only clicks through to another XML screen-- you have no idea how long it took me to make it work correctly)
Code:
package com.android.obewah.baristame;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class BaristaMeActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.startup);
final Button button = (Button) findViewById(R.id.startupBU);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click {
setContentView(R.layout.main);};}
);}}
I am still trying to wrap my brain around how I am going to put in the recipes.
My current plan of action is to create a scroll menu that pops up when you select a category (via button on main page) that leads you to an XML of the recipe.
However this seems like it may be an unnecessarily difficult approach. I don't plan to have an option of adding recipes from the app just for it to be a reference.
Thoughts/Comments?

Might i suggest not just changing the layout in the onClickListener but calling startActivity and changing to an Activity that has that layout. This will preserve the back buttons functionality without a bunch of overriding it.

Don't Overload a Single Activity Screen
Any application worth using will probably have several different screens. When designing the screens of your UI, be sure to make use of multiple Activity object instances.
Depending on your development background, you may interpret an Activity as similar to something like a Java Applet, in that it is the entry point for your application. However, that's not quite accurate: where an Applet subclass is the single entry point for a Java Applet, an Activity should be thought of as one of potentially several entry points to your application. The only difference between your "main" Activity and any others you might have is that the "main" one just happens to be the only one that expressed an interest in the "android.intent.action.MAIN" action in your AndroidManifest..xml file.
So, when designing your application, think of your application as a federation of Activity objects. This will make your code a lot more maintainable in the long run, and as a nice side effect also plays nicely with Android's application history and "backstack" model.

do you know any html coding? because you can use a webview to load a .html file from R.raw.file.html. i have done this with my change log on my app. also if you using strings.xml have a look at using the \n to add a new link.

Update 3
Well the first two buttons took me about two hours each. Then the next 8 or so took 15 min.
Here is what the code looks like atm; can anyone tell me how to make the back button cause it to go back one step in the program and not exit?
Code:
package com.android.obewah.baristame;
import android.app.Activity;
import android.content.pm.ActivityInfo;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.View;
import android.view.Window;
import android.widget.Button;
public class BaristaMeActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.setRequestedOrientation(
ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
setContentView(R.layout.startup);
Button startupBU = (Button) findViewById(R.id.startupBU);
startupBU.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Perform action on click
setContentView(R.layout.main);
//start rec. buttons
}
});}
Class mystuff;
public void toreci(View v) {
setContentView(R.layout.make);
}
public void toramer(View v) {
setContentView(R.layout.ramer);
}
public void tohome(View v) {
setContentView(R.layout.main);
}
public void torcapp(View v) {
setContentView(R.layout.rcapp);
}
public void torlatt(View v) {
setContentView(R.layout.rlatt);
}
public void torbrev(View v) {
setContentView(R.layout.rbrev);
}
public void tordopp(View v) {
setContentView(R.layout.rdopp);
}
public void toriame(View v) {
setContentView(R.layout.riame);
}
public void torilat(View v) {
setContentView(R.layout.rilat);
}
public void toribre(View v) {
setContentView(R.layout.ribre);
}
public void test(View v) {
setContentView(R.layout.test);
}
}

Agree with killersnowman, don't overload the activity.
Have a recipe activity and layout. Make the button start the recipe activity and pass extra's (ints, strings, booleans) across in a bundle.
Here is an example on how to do it.
http://droidapp.co.uk/?p=48
Make the recipe activity read from the bundle, and then populate textviews / images etc based on them.

Ok, I have some dumb questions for you please forgive me in advance.
1) So what you are trying to tell me is to create another .java activity file that the main activity forwards to in order to preserve the integrity of the main activity. This new activity should be activated by the click here to start button and it will have all of the button code in it:
Code:
public void tolabou(View v) {
setContentView(R.layout.lcoff);
}
public void toldrip(View v) {
setContentView(R.layout.ldrip);
}
public void tolflav(View v) {
setContentView(R.layout.lflav);
Is that right?
2) Can you give me a idiot friendly definition of "activity, ints, strings, booleans, and bundle" and how they compliment each other
3) Right now I have a layout.xml for each recipe is that bad?
Feel free to answered all or any part of those questions and again I am truly grateful for all of the help I have received!

Well i can answer #2.
For more on activities: http://developer.android.com/reference/android/app/Activity.html
An activity is like each "part" of a program. You can have as any as you want. The main one gets called by the launcher to start the app.
For variable types look at: http://download.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html
Int = number without decimal (-7,0,1,8) -2,147,483,647 to 2,147,483,647 max.
for decimals use float or double
string = text. ("Hello World!")
boolean = true/false (1/0, on/off, whatever).
bundle = some android thing. I believe it can save the state of your program to resume and stuff.
For future referance:
Java Tutorials: http://download.oracle.com/javase/tutorial/index.html (Lots of good stuff for starting programming and java)
Android Dev: http://developer.android.com/guide/index.html (Android specific stuff)

OK, I'll try to explain the process:
Main Screen:
1 Activity : main.java (This is the Java class, contain java code)
1 Layout : main.xml (This is the XML layout, linked to the class in setContentView)
Recipe Screen:
1 Activity : recipe.java
1 Layout : recipe.xml
So if in the main screen there are 2 buttons ("Lasagne" and "Pasta Bake"). Pressing either of these buttons will launch the recipe screen, but will pass a different string in the bundle to the new activity:
Code:
LasagneButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
Intent myintent = new Intent("com.whatever.whateverapp.RECIPE");
Bundle mybundle = new Bundle();
mybundle.putString("recipename", "lasagne");
myintent.putExtras(mybundle);
startActivity(myintent);
}
});
The code above is creating a new intent, and a bundle. Adding a string called "recipename" to the bundle and setting it's value to "lasagne". This bundle is then added to the intent, and the activity is started. For the second button you would do exactly the same but set the string to "PastaBake".
So now when the recipe activity starts you need to extract the string, the next code should be placed under onCreate in your recipe activity:
Code:
Bundle mybundle = getIntent().getExtras();
String recipename = mybundle.getString("recipename");
Now with this recipename string you will need to populate your layout.
Hope that makes it a bit clearer. Here are some short tutorials I have written that may help you understand the basics a bit more (BTW: I am no expert, and have only been programming Android / Java for 6 months or so):
Buttons & Actions: http://droidapp.co.uk/?p=4
Changing Screens: http://droidapp.co.uk/?p=24
You will need to read and understand the second one to understand setting up activities as they need to be declared in the AndroidManifest file.

LinearLayout Hyperlink

Hello!
First at all, I'm a beginner in android coding, I'm more a graphist with Photoshop as main tool.
A friend has made an app for my themes and is in holidays until september.
Beeing logical and understanding fast, with my friend Google we found the functions/codes I needed. Except one:
I have a horizontal scroll layout showing the apps needed to install the theme. Each app is showed in a linearlayout.
What I would like is make each linearlayout of apps clickable and make them show the app on the playstore when you click on it.
Thanks for reading

I assume you're using Textviews to add line by line the dependencies.. There is a property called autolink or very much like it that makes a link whenever it finds a url in the text...
But instead of Textviews in a linearlayout, why not use ListView? Then you can handle the click in the item to create an intent to open the browser with the url needed... it's a bit of more work but has a better esthetic than a bunch of TextViews... For instance, it makes it easier to use when in a ldpi device...

Sorry for the late.
I'm beginner in java coding so I don't undersand well what you mean dude.
In fact, what I have now is:
In res\layout\main.xml:
Code:
<HorizontalScrollView
android:id="@+id/layout5"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/layout3"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginTop="8dp"
>
<LinearLayout
android:id="@+id/layout4"
android:background="#00000000"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
</HorizontalScrollView>
In MainActivity.java:
Code:
boolean apexInstalled = appInstalledOrNot("com.anddoes.launcher");
RelativeLayout apexApp = (RelativeLayout) getLayoutInflater().inflate(R.layout.item, null);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams((int) (125 * scale + 0.5f),(int) (150 * scale + 0.5f));
ImageView apexI = (ImageView) apexApp.findViewById(R.id.appIcon);
apexI.setBackgroundResource(R.drawable.apexicon);
TextView apexT = (TextView) apexApp.findViewById(R.id.appText);
if(apexInstalled){
apexT.setText(R.string.installe);
apexT.setTextColor(Color.parseColor("#5a925d"));
}
else{
apexT.setText(R.string.nninstalle);
apexT.setTextColor(Color.parseColor("#de3747"));
}
apexT.setTypeface(font);
TextView apexTitle = (TextView) apexApp.findViewById(R.id.appTitle);
apexTitle.setText("Apex Launcher"); // \n == retour a la ligne
apexTitle.setTypeface(font);
apexApp.setBackgroundColor(Color.argb(190, 0, 0, 0));
listApp.addView(apexApp, params);
And I have many blocks like this one but with other apps, and I would like them to point on the playstore, what do I have to add?

Use a ListView with a custom Adapter: http://www.vogella.com/articles/AndroidListView/
Then add an OnItemClickedListener to the ListView.
In its onItemClick method you can use an Intent like this one:
Code:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getActivity().getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(getActivity(), "Google Play is not installed on the device.", Toast.LENGTH_LONG).show();
}

Thanks trying to help me, but I understand aproximatively the intent, but the listview etc, no..
I'm just trying to modify a bit an app somebody made for me using my logic to understand what I have to do. The problem is that I don't understand how to apply what you tell me :/

OK, then let's forget about the ListView if you just want to modify your existing app with as little effort as possible.
Try that in your Java code:
Code:
LinearLayout layout = findViewById(R.id.layout4);
layout.setClickable(true);
layout.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getActivity().getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(getActivity(), "Google Play is not installed on the device.", Toast.LENGTH_LONG).show();
}
}
});
(The word Override has to be written with a capital letter at the beginning. XDA does not allow that.)

But if I understand well that code, it will make a "link case" in the whole scroll layout no?
Or a link for each app?
If it's not possible to cut the horizontal scroll in little squares (links), is that possible to put a hyperlink on each imageview? So that click on the icon shows the store.

Yes, it does. I thought that the Linear layout was loaded as the layout for each app.
Ok. I think that the RelativeLayout in the MainActivity.java is your row, right?
If it is, that should work:
Code:
apexApp.setClickable(true);
apexApp.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getActivity().getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(getActivity(), "Google Play is not installed on the device.", Toast.LENGTH_LONG).show();
}
}
});

Yeah, each RelativeLayout is an app square. I'm not at home so I can't test it now, will later in the evening, thanks for your help!

Ah, you're right. I'm sorry.
I copied the code from one of my fragments. Just delete the getActivity().
So it is:
Code:
apexApp.setClickable(true);
apexApp.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(MainActivtiy.this, "Google Play is not installed on the device.", Toast.LENGTH_LONG).show(); //replace the MainActivity by your Activity
}
}
});

Action Bar and OptionsMenu troubleshooting

I just discovered how to use the action bar to have a OptionsMenu. I just solved a problem with it and I wanted to know if I did it the right way.
What I did
So, I added the menu to a fragment started by an activity, adding to it the setHasOptionsMenu(true) in the onCreate method and setting up the two convenience methods public void onCreateOptionsMenu() and public boolean onOptionsItemSelected() of course setting up the xml first.
The problem
Now, if I rotate my device in landscape mode the button in the action bar duplicates. If I put it in portrait mode again, the number of items stays the same (I'm sure it doesn't actually increase, checked the size in different ways) though.
What I thought and how I solved it
So, I was thinking about some fragment overlaps, but if they actually overlap then I shouldn't notice anything, right?
Is the menu being recreated, while not destroyed when the fragment is destroyed?
I solved the problem removing the item in the menu, in the Fragment.onDestroy() method manually.
Is the menu supposed to be cleared manually, or there is something wrong with my code (eg. fragments overlapping, etc..) ?

Of course. Thanks for the interest.
This is the onCreate method of MainActivity.java, from where I handle the arrangement of fragments on the screen.
Also, place check my comment under the line "Log.d(TAG, "Orientation Portrait detected.");", where I try to explain why I handle fragments in that specific way. It's the way I understood it, but I'm not sure if that's correct.
Code:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Initialize the mDatabase
mContactsDatabase = ContactsDatabase.getInstance(getApplicationContext());
// Determine device orientation
mDualPane = getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE;
// Set the fragment that will be changed
mFragmentToReplace = mDualPane ? R.id.contactsPagerFragmentContainer : R.id.portraitFragmentContainer;
// Set up the GUI
FragmentManager fm = getSupportFragmentManager();
if (!mDualPane) {
Log.d(TAG, "Orientation Portrait detected.");
// First, look for previously saved fragments
// findByFragmentId(int id) look for the fragment that was previously associated
// to the resource that has for id the argument passed in. Then, we try to cast it

// Else, null will be returned.
mContactListFragment = (ContactListFragment) fm.findFragmentById(R.id.portraitFragmentContainer);
if (mContactListFragment == null) {
mContactListFragment = ContactListFragment.newInstance(mContactsDatabase);
fm.beginTransaction()
.replace(R.id.portraitFragmentContainer, mContactListFragment)
.commit();
}
}
else {
Log.d(TAG, "Orientation Landscape detected.");
// First, look for previously saved fragments
mContactListFragment = (ContactListFragment) fm.findFragmentById(R.id.landscapeFragmentContainer);
mContactsPagerFragment = (ContactsPagerFragment) fm.findFragmentById(R.id.contactsPagerFragmentContainer);
if (mContactListFragment == null) {
mContactListFragment = ContactListFragment.newInstance(mContactsDatabase);
fm.beginTransaction()
.replace(R.id.contactListFragmentContainer, mContactListFragment)
.commit();
}
if (mContactsPagerFragment == null) {
final int FIRST_CONTACT_POSITION = 0;
mContactListFragment = ContactListFragment.newInstance(mContactsDatabase);
mContactsPagerFragment =
ContactsPagerFragment.newInstance(FIRST_CONTACT_POSITION, mContactsDatabase);
fm.beginTransaction()
.replace(R.id.contactsPagerFragmentContainer, mContactsPagerFragment)
.commit();
}
}
}
This are the relevant pieces of the ContactListFragment.java, that have something to do with the menu
Note that I changed the way I checked for double menu entries.
Now I check if (menu.size() != 1), because I have just one item in there.
If I remove that clause, there will be two item in the menu after rotating to landscape mode, and if I take the device back to portrait mode, the two items will remain two. That's so even if I change from landscape to portrait and vice versa a hundred times from now, the menu items will always be two.
Code:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
Bundle args = getArguments();
mDatabase = (ContactsDatabase) args.getSerializable(DATABASE);
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
if (menu.size() != 1) {
inflater.inflate(R.menu.contact_list_fragment_menu, menu);
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.addContactMenu:
mCallback.onAddContactMenuOptionSelected();
default:
return super.onOptionsItemSelected(item);
}
}

I just discovered how to use the action bar to have a OptionsMenu. I just solved a problem with it and I wanted to know if I did it the right way.
What I did
So, I added the menu to a fragment started by an activity, adding to it the setHasOptionsMenu(true) in the onCreate method and setting up the two convenience methods public void onCreateOptionsMenu() and public boolean onOptionsItemSelected() of course setting up the xml first.
The problem
Now, if I rotate my device in landscape mode the button in the action bar duplicates. If I put it in portrait mode again, the number of items stays the same (I'm sure it doesn't actually increase, checked the size in different ways) though.
What I thought and how I solved it
So, I was thinking about some fragment overlaps, but if they actually overlap then I shouldn't notice anything, right?
Is the menu being recreated, while not destroyed when the fragment is destroyed?
I solved the problem removing the item in the menu, in the Fragment.onDestroy() method manually.
Is the menu supposed to be cleared manually, or there is something wrong with my code (eg. fragments overlapping, etc..) ?

I agree with nikwen but broadly the idea is...
- the menu belongs to the Activity not the Fragment.
- for an Activity for which you'd like an options menu you override onCreateOptionsMenu and do 2 things...
1/ call menu.add(...) for each menu item
2/ return 'true' at the end, so that your menu can be displayed
Also, see the Activity docs for onCreateOptionsMenu()
"This is only called once, the first time the options menu is displayed.
To update the menu every time it is displayed, see onPrepareOptionsMenu(Menu)."
If you want to add menu options to the Activity menu from within a Fragment you can also..
- override setHasOptionsMenu() in Fragment to return true
- override onCreateOptionsMenu() to add any items you like (just like you did at the Activity level)
- override onDestroyOptionsMenu()
The key thing here is that onCreateOptionsMenu() in Fragment is adding to the Activity menu.
It's hard to see without debugging exactly what's going on here but watch for calls to all of the above methods in Activity and Fragment and that will probably tell you what's going on.
If it is possible to control all menu options at the Activity level instead of the Fragment level, I would do that.
If not, and you need to use the Fragment menu methods, beware of Android's Fragment management (saving / restoring state)
Also, make sure your Fragments have an ID and/or tag.
(from the docs..)
"The fragment being instantiated must have some kind of unique identifier so that it can be re-associated with a previous instance if the parent activity needs to be destroyed and recreated. This can be provided these ways:
If nothing is explicitly supplied, the view ID of the container will be used.
android:tag can be used in <fragment> to provide a specific tag name for the fragment.
android:id can be used in <fragment> to provide a specific identifier for the fragment."
Finally, if all else fails, using Menu's findItem() before calling add() would be a safeguard, I suppose.

Sorry caught in the crossfire - have only just seen your code.
I think much of the above applies.
Set the menu up in the Activity instead of the Fragment, if you can.
I would also consider using layout-port and layout-land to control your two different layouts.

Wow. thanks for that detailed answer. :good: (Why have I used all my thanks?)
I've always put it into the Activity as well but it might make sense to add it to the Fragment sometimes. For example if you need the same Fragment in multiple Activities...
In that case you'd need to add a listener to the item in the Fragment method though.

@PicomatStudio Thank you for the detailed answer, I really appreciate that =)
Now I'm creating the menu in the activity and I don't have to worry about the fragments life cycle anymore.
The only problem is: I didn't get the menuInflater for free here, I guess it's because of the fact that in the Fragment scenario, I had to use the Activity inflater, whereas here in the activity, I can get my own, with getMenuInflater().
Here's the way I modified it, now is in MainActivity.java.
Please report back if you find something strange
Code:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
if (getSupportFragmentManager().findFragmentByTag(CONTACT_LIST_FRAGMENT) != null)
getMenuInflater().inflate(R.menu.contact_list_fragment_menu, menu);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.addContactMenu:
onAddContactMenuOptionSelected();
default:
return super.onOptionsItemSelected(item);
}
}

I don't tend to use MenuInflater (just menu.add()..)
But looking at the docs it takes a Context so could you do..
Code:
new MenuInflater(this);
.. from your Activity ?
On a general design point the less your Activity depends on its Fragments the better, I reckon.

[Tutorial] Learn to create a Matrix Effect

Hello,
I create that thread to present you a tutorial learning you how to create a Matrix Effect, also known as Digital Rain Effect, on Android. The tutorial is also available as a Youtube video :
Create a Matrix Effect on Android
Also know as Digital Rain Effect, the Matrix Effect is a classic effect featured in the Matrix series films. A green code is falling and represents the activity of the virtual reality environment of the Matrix on screen. On Android, Matrix Effect has been implemented in various applications often as a Live Wallpaper. In that tutorial, you are going to learn how to create a simple Matrix Effect.
1. Create a Matrix Effect custom View
First, you need to create a custom view named MatrixEffect :
Code:
package com.ssaurel.digitalraineffect;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.view.View;
import java.util.Random;
/**
* Created by ssaurel on 22/09/2016.
*/
public class MatrixEffect extends View {
private static final Random RANDOM = new Random();
private int width, height;
private Canvas canvas;
private Bitmap canvasBmp;
private int fontSize = 40;
private int columnSize;
private char[] cars = "+-*/!^'([])#@&?,=$€°|%".toCharArray();
private int[] txtPosByColumn;
private Paint paintTxt, paintBg, paintBgBmp, paintInitBg;
public MatrixEffect(Context context, AttributeSet attrs) {
super(context, attrs);
paintTxt = new Paint();
paintTxt.setStyle(Paint.Style.FILL);
paintTxt.setColor(Color.GREEN);
paintTxt.setTextSize(fontSize);
paintBg = new Paint();
paintBg.setColor(Color.BLACK);
paintBg.setAlpha(5);
paintBg.setStyle(Paint.Style.FILL);
paintBgBmp = new Paint();
paintBgBmp.setColor(Color.BLACK);
paintInitBg = new Paint();
paintInitBg.setColor(Color.BLACK);
paintInitBg.setAlpha(255);
paintInitBg.setStyle(Paint.Style.FILL);
}
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
width = w;
height = h;
canvasBmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
canvas = new Canvas(canvasBmp);
canvas.drawRect(0, 0, width, height, paintInitBg);
columnSize = width / fontSize;
txtPosByColumn = new int[columnSize + 1];
for (int x = 0; x < columnSize; x++) {
txtPosByColumn[x] = RANDOM.nextInt(height / 2) + 1;
}
}
private void drawText() {
for (int i = 0; i < txtPosByColumn.length; i++) {
canvas.drawText("" + cars[RANDOM.nextInt(cars.length)], i * fontSize, txtPosByColumn[i] * fontSize, paintTxt);
if (txtPosByColumn[i] * fontSize > height && Math.random() > 0.975) {
txtPosByColumn[i] = 0;
}
txtPosByColumn[i]++;
}
}
private void drawCanvas() {
canvas.drawRect(0, 0, width, height, paintBg);
drawText();
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.drawBitmap(canvasBmp, 0, 0, paintBgBmp);
drawCanvas();
invalidate();
}
}
First, we define the variables for the Matrix Effect with the size of the code, the size of a column, the position of the bottom text for each column and then the caracters that will be used for the code. Note that you can put the caracters you want here or why not a custom font.
In the constructor, we initialize the paint objects. To get view width and height, we override the onSizeChanged method of the View. We initialize the position of the first caracter for each column. We use a random position between the top of the screen and the middle of the screen.
Then, we define a draw text method used to draw a random caracter for each column at the position indicated by txtPosByColumn variable.
The drawCanvas method is used to draw the background of our view and then the code.
Finally, we override the onDraw method of our custom view to call the drawCanvas method and invalidate the view to force a redraw. With that call, the Matrix Effect could progress from top to bottom in infinite mode. Note that it is not the most optimized way to manage a Matrix Effect, but for a tutorial it's sufficient.
2. Define the MatrixEffect View on the Layout
Now, we can define the MatrixEffect View on the layout of the Main Activity.
Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.ssaurel.digitalraineffect.MainActivity">
<com.ssaurel.digitalraineffect.MatrixEffect
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
3. Set the layout on the Main Activity
Last step is to set the layout as content view for the Main Activity.
Code:
package com.ssaurel.digitalraineffect;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
4. Demo
To enjoy the Matrix Effect, you have just to launch the application on an Android device and you sould see the following effect :
Don't hesitate to give it a try and give me your feedbacks.
Thanks.

I really like this animated wallpaper app.

Thanks for the detailed tutorial, it's always nice to see actually what the code does. :highfive:
In theory, would it be possible to take smali from the app you create and use it to create this effect on the notification screen (for example)?

Seeing the code I’m sure this app drain a lot of battery but it's very nice.

Did you mean put the effect on the lock screen ? I thought it was not possible now to put live wallpaper on lock screen. If it's possible it could be great.

For sure . But life is a choice, like in Matrix films, cool effect on your screen or save your battery lol

Should be possible to pull the AOSP lockscreen source (or the source from OEM variants that are actually available...) and replace the wallpaper code, right?

Hello! nice tutorial, everything works fine. But I would like to add buttons to change the colors of chars but i'm not able to call the method from the main activity.
I've tried this but giving errors
Code:
MatrixEffect matrixEffect = new MatrixEffect(); // this gives an error : MatrixEffect(Context, AttributSet) in MatrixEffect cannot be applied to ()
final Paint paintTxt = effetMatrix.peindreTxt;
paintTxt.setColor(Color.BLUE);
Is there a way that I can call paintTxt.setColor() to change color?
PS: Im just a noob on programming

If you want to add buttons to change the color of the Matrix Effect, you should work on the layout and add two buttons at the bottom of the screen under the MatrixView. The, you have to change the colors of the Matrix Effect when a user click on one of these buttons.

Already solved. I added 4 buttons for 4 colors and i used switch statement
1st, created a custom text color inside MAtrixEffect
Code:
public void setCustomTextColor(int color){
peindreTxt.setColor(color);
invalidate();
then, in mainactivity :
Code:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
MatrixEffect matrixEffect;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
matrixEffect = (MatrixEffect) findViewById(R.id.arrPlan);
final Button boutton_blanc = (Button) findViewById(R.id.b_bl);
final Button boutton_bleu = (Button) findViewById(R.id.b_b);
final Button boutton_rouge = (Button) findViewById(R.id.b_r);
final Button boutton_rose = (Button) findViewById(R.id.b_ro);
if (boutton_bleu != null) {
boutton_bleu.setOnClickListener(this);
}
if (boutton_blanc != null) {
boutton_blanc.setOnClickListener(this);
}
if (boutton_rouge != null) {
boutton_rouge.setOnClickListener(this);
}
if (boutton_rose != null) {
boutton_rose.setOnClickListener(this);
}
}
@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.b_bl:
matrixEffect.setCustomTextColor(Color.WHITE);
break;
case R.id.b_b:
matrixEffect.setCustomTextColor(Color.BLUE);
break;
case R.id.b_ro:
matrixEffectsetCustomTextColor(Color.MAGENTA);
break;
case R.id.b_r:
matrixEffect.setCustomTextColor(Color.RED);
break;
case R.id.b_def:
matrixEffect.setCustomTextColor(Color.GREEN);
break;
}
}
}
Now it works fine and i can change color while a button is pressed
