Hi guys,
On a button click I am inflating a layout like so:
Code:
public void plusLayout(View v) {
// inflating layout here:
LinearLayout ll1 = (LinearLayout) findViewById(R.id.main_layout);
// this layout is being inflated:
View newView = getLayoutInflater().inflate(R.layout.layout_to_be_added, null);
// add layout
ll1.addView(newView);
}
But when the activity restarts, the inflated layouts are gone.
I'd like the layouts to stay there.
(The user can click a button to remove the layout by hand).
I must be missing something trivial here right?
Cheers,
Daan
Which way is it restarted?
If the complete app is restarted, a new layout will be set in the onCreate method.

Yeah when you press back button and start the app again or completely kill it.
It also happens on orientation change as the activity get restarted then as well.
But I think you can override that in the manifest somewhere.

Ah ok.
The point is: If you open the app or turn your device, the onCreate method is called. There you set a completely new layout. You would need to save that the layout is inflated (you could use a SharedPreferences entry) and inflate it in the onCreate method. If you just want it to appear again after turning the device, use the onSaveInstanceState method and the onRestoreInstanceState method. That would be better practice.
Look at the activity lifecycle.
Just so I'm sure I get this right :
The user launches the app, the layouts are not inflated
He presses a button which calls your plusLayout() method, so the layouts are now inflated
The user quits the activity and restarts it, the layouts are not inflated anymore but you want them to.
Is that correct ?
If it is, 2 ways I can think of :
Overriding savedInstanceState() & onRestoreInstanceState() :
First, declare a private Boolean before the onCreate() of your activity :
Code:
private Boolean isInflated = false;
Then, set it to true in the onClick() of your button, and override savedInstanceState and onRestoreInstanceState like so :
Code:
@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
// Save state changes to the savedInstanceState.
// This bundle will be passed to onCreate if th activity is
// killed and restarted.
savedInstanceState.putBoolean("inflate", isInflated);
}
Code:
@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// Restore UI state from the savedInstanceState.
// This bundle has also been passed to onCreate.
Boolean myBoolean = savedInstanceState.getBoolean("inflate");
if (myBoolean == true)
plusLayout(myView);
}
Using the sharedPreferences
Same logic, different way to save the boolean :
Before onCreate(), declare a private boolean and a private SharedPreferences :
Code:
private Boolean isInflated = false;
private SharedPreferences prefs = getSharedPreferences("MY_PREFS");
in the onClick of your button :
Code:
isInflated = true;
Editor e = prefs.edit();
e.putBoolean("inflate", isInflated);
e.commit();
Then, in your onCreate(), retrieve the stored value and if it's true, call your plusLayout() method :
Code:
Boolean doInflate = prefs.getBoolean("inflate", false // this is the default value);
if (doInflate == true)
plusLayout(myView);

Okay I'm working on that at the moment.
Whenever a layout is created an (int) "counter" get incremented.
I will save this "counter" in the SharedPreferences.
When the app starts layouts get created "counter" times.
Is this good practice?
It seems so strange that there isn't an easier way to save layout/activity states.

I would use his snippets. They are good (as always). Decide which one to use by what I have given above:
Just for turning:
onSaveInstanceState and onRestoreSavedInstanceState
For turning and reopening:
Shared preferences
Hi All!
I'm new here and new to the Android Eclipse/development side and I'm having a bit of a problem with a java script.
I have a small advertising app with 2 buttons (looking to expand to 4 but that's a different thread), one for Facebook (Button1) and one for Twitter (Button2) and Button2 won't work until Button1 is clicked. It works fine except for that.
Any ideas on solutions? Aggravating me a bit lol
Thanks!!
We will need to see your layout XML and java code to help out.
not sure how i'd do that atm cos im a new member? i know that some admin members get pi**y when you dont wrap any code for formatting reasons??
i've got ready and i can imagine a senior member such as yourself will notice the mistake straight away.
Use pastebin http://pastebin.com/
not sure how to use it, just tried and i got the same message about not being able to post things outside links until 10 posts and so on? even tried pasting the raw text and still wouldnt let me
any suggestions?
thanks
Or use the CODE tags: [CODE ] and [/CODE ], but without the extra spaces.

You had your button definition in the wrong place for your twitter button

[user=439709]@override[/user]

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); //Set the screen's view to your xml file
Button facebookbutton = (Button) findViewById(R.id.button1); // Retrieve the button from the XML file
facebookbutton.setOnClickListener(new View.OnClickListener() { //Add a listener for when the button is pressed
[user=439709]@override[/user]
public void onClick(View v) {
sendToFacebook();
}
});
Button twitterbutton = (Button) findViewById(R.id.button2); // Retrieve the button from the XML file
twitterbutton.setOnClickListener(new View.OnClickListener() { //Add a listener for when the button is pressed
[user=439709]@override[/user]
public void onClick(View v) {
sendToTwitter();
}
});
}
protected void sendToFacebook() {
String url = "https://www.facebook.com"; // You could have this at the top of the class as a constant, or pass it in as a method variable, if you wish to send to multiple websites
Intent i = new Intent(Intent.ACTION_VIEW); // Create a new intent - stating you want to 'view something'
i.setData(Uri.parse(url)); // Add the url data (allowing android to realise you want to open the browser)
startActivity(i); // Go go go!
}
protected void sendToTwitter() {
String url = "https://www.twitter.com"; // You could have this at the top of the class as a constant, or pass it in as a method variable, if you wish to send to multiple websites

}
}
Thanks for that ill give that a try!!! Really appreciate it
Sent from my GT-I9305 using xda app-developers app
it works!!! would i just repeat that for any additional buttons, same format;
Button onclicklistener etc etc etc
Button onclicklistener etc etc etc
protected void
protected void
and so on
does it work like that?
thanks!
Yes, just besure you place the code in your onCreate method for defining your buttons
Ill remember that haha thanks again really appreciate it!! =D

Hey zalez
I just tried adding a youtube button in the exact same format obviously changing the button source and so on, eclipse couldn't find any problems so I ran it and it just crashed the app on the avd and on a real device?

There are multiple ways. I like setting a listener, then using an onClick method with switch-case statements for every button.

you've lost me lol i understand the onclick but switch cases? if you check my .xml and .java from pastebin or the .java that another member posted further up ^ ^ ^ ^ that might show where im going wrong?
edit *** i just googled the switch case thing and ive seen it before, just not sure how i'd implement it into my .java?
thanks

Sorry, I'm away. I'll look up an example from one of my apps later.
Basically, just make an onClickListener. You are then required to use that interface and implement the onClick method. Do that, you have an empty method, with a parameter like View v.
Then, make a switch statement for v.getId(), and do cases for the buttons (use their XML IDs!) that you have.
Hope that's kind of clear?

That's actually starting to make sense! But it's just putting that into a script, not really my strong point yet, I'm more of a designer lol
It would be good if you could find some examples for URL buttons, it'd really help. Thanks!
There shouldn't have been any issues adding more. I would need to see your updated java code. Using switch cases is a good idea but at this point, if I was you, I would avoid it for now until you get the hang of the basics. Also, a log cat would be beneficial in debugging.

That link didn't work, but if you Google 'android java button onclick listener' that will get you started with plenty of helpful links.
When the button is clicked, you then need to check the content of the Edit Text field - Something like this:
Code:
public void onClick(final View v) {
final String commandText = inputText.getText().toString();
if (commandText != null && commandText.length() > 0) {
Where inputText is the Edit Text field you've assigned in your OnCreate method.
Getting started involves a lot of head scratching, but don't give up! There's so much Open Source code out there, that the penny will drop soon.

Paste code (variables, functions, etc) inside your MainActivity class and don't write 3 dots, it's just a replacement for skipped parts

You need to import TextView and Intent first. Just hover over the names and select import from the menu you will see.
Seriously, my advice would be to learn and understand Java first. It doesn't make sense to learn Android if you don't know Java (and it won't work).

Unless you know any other similar languages. Java was the easiest lang to learn for me, after years of writing on Object Pascal/Object C/C++/JavaScript/PHP. The most troublesome part of coding for Android is creating an UI, especially cross-version compatible :laugh:
Hi guys,
i've started making an app recently.. and i needed a task to run in the backgound every 2 or 5 minutes.. and i collect the data and i display it when the app is opened.. so am using a sync task.... I'm having a bit of diffculty unerstanding how its used as every example is different..
and FYI am using a seperate .java file to runt he asynctask...
When we go through the android developers page this is the code we see...
They start with
Code:
private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
1) whats the deal with the URL Integer Long ????? If i skip it what will happen???
next is this
Code:
protected void onProgressUpdate(Integer... progress) { setProgressPercent(progress[0]);
2) whats the integer doig there?? even if its not used in the function they put it... whats the deal??
3) Also how do we pass values like strings to a class??? i know about functions but the functions used in this class are like a group like so i cant exactly pass values to just one particular function...

then when you will call its object then it will like this.
Code:
public class async extends AsyncTask<int , Progress , Result>{
}
async c;
c.execute(10); // passed int value 10 to execute the async thread in the background...
it has 3 methods that should be implemented
Code:
class load extends AsyncTask<int, Void, Void>{
@Override

// TODO Auto-generated method stub
// all the ui updation is done here after doing the calculation...

OK, so you're probably using it in a service, aren't you?
First of all, carefully read the tutorials here and here on vogella, to help you understand what it does.
1) these are the type of variables that are passed to the respective methods:
An asynchronous task is defined by 3 generic types, called Params, Progress and Result, and 4 steps, called onPreExecute, doInBackground, onProgressUpdate and onPostExecute
Click to expand...
Click to collapse
The Params get passed to the onPreExecute method, the Progress is the one you need to pass calling publishProgress and which is passed to onProgressUpdate. The result one should be returned by your doInBackground method and gets passed to the onPostExecute.
2) the Integer... Is actually an array of the corresponding object to int. Just ignore it and use the progress[0] as if it was a normal int.
3) set your Params variable to String so
AsyncTask <String, Integer, String> if you want to return a string as well
Ok i think i'm getting it... But when we say "Params , Progress , Result" its still a bit confusing..
we first hit pre execute then do iin BG then post execute... But the order in which the params are stated are not the same ...
when i give string first it always takes it for the during BG process... not for the pre execute...
For ex i say asymctask<int, string,void>
so my pre execute should get a int..
then my bg process should get a string..
the post execute should get nothing..
am i right???

Almost, the Progress variable is passed to the onProgressUpdate. This is something to indicate progress and publish on the UI Thread (for instance update a progress bar), usually an Integer. You can update the Progress from your doInBackground method by calling publishProgress, passing a Progress variable.
The point of this is that the doInBackground method runs in a seperate thread and all other methods run in the UI Thread! So you can't directly pass data between those, only with these values. Consider using a Bundle if you want to pass more than one variable!
