[Q] Why cant I call a method from another class?

I have 2 classes in one .java file and it runs fine without errors or anything (the second class is used as a timer and changes variables every second) everything works but it wont call methods properly. Any idea of why this would be??? Heres my code of the second class.
Code:
class MyTime extends TimerTask{
//java.text.DateFormat format = SimpleDateFormat.getTimeInstance(SimpleDateFormat.MEDIUM, Locale.getDefault());
public game timecall2= new game();
public MyTime(Context ctx) {
// create internal instance
Context ctx2;
}
@Override
public void run() {
game.sec--;
if(game.sec==-1){game.sec=59;game.min--;}
game.Title2(); // set text in title bar
}
}

It would be easier if you explain more cleary, what you want to do.
Or post more code.
public game timecall2= new game();
I think, game is your first class?
Then you want to use the variable sec of the class game?
-> are they declared as static or why you don't call it over the object timecall2 you created?
Sry, but without more Code/Information to unterstand your problem, it's difficult to help. Also don't know, how skilled your are in programming.

*game* is the first class
I've tried calling the method through *timecall2* object but it doesn't help.
I've tried declaring the function as both static and no-static but nothing seems to change.
I've got lots of programming experience in other languages, but I'm less experienced with Java

And what's going wrong now?
Why don't you debug trough the code. Should be the easiest ways to find the problem.

You generally should use getters and setters for accessing variables inside of another class. Meaning that you have a method to set the value of the variable and a method to retrieve the value
Code:
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class MyClass extends Activity {
private static int mMin = 0;
private static int mSec = 0;
private TextView titleText;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView titleText = (TextView) findViewById(R.id.titleText);
}
public static int getSec() {
return mSec;
}
public static void setSec(int newVal) {
mSec = newVal;
}
public static int getMin() {
return mMin;
}
public static void setMin(int newVal) {
mMin = newVal;
}
public static void setTitleText(String newVal) {
if (titleText != null) {
titleText.setText(newVal);
}
}
}
Notice the "static" modifier of the class methods.
Generally, you wouldn't instantiate this activity class. Especially if it already lives in memory. What I am guessing that you are doing here is that "game" is your activity and that MyTime is an object that you are using from inside of the activity and that you need to modify variables that live in the main Activity.
If that is the case then you would just do something like this:
Code:
import java.util.TimerTask;
import com.myapp.game.MyActivity;
class MyTime extends TimerTask {
private int sec = 0;
private int min = 0;
@Override
public void run() {
sec = MyActivity.getSec();
min = MyActivity.getMin();
sec--;
if(sec==-1) {
sec=59;
min--;
}
String title = String.valueOf(min)+":"+String.valueOf(sec); //obviously you need formatting
MyActivity.SetTitle(title); // set text in title bar
MyActivity.setSec(sec);
MyActivity.setMin(min);
}
}
That said... I just did the above as an example. This is entirely the wrong way to make a game timer. There is a better example here

From what I remember from C++, you would have a "base" class and then other classes beneath that base class.
To use the base class methods, the other classes had to be "friends". I'm a little rusty on my JAVA syntax...is "extends" the same thing as a friend class?

Java doesn't have friend functions, and "extends" means that the class is a subclass of whatever its extending.

To access a function/variable between classes that said function/variable must be static. Beware tho when do this depending on you implementation you must check for null variables. Since its static you can access you dont need a class object to access them through.
ak. SomeClass.function();
instead of using SomClass sc = new SomeClass(); sc.function();
since u can access it at any time its contents may not be initialized and be null. So ALWAYS check for null varaibles! lol. That or u can have one variable of that class to check if its class is initialized. such as..
SomeFunction.isInit();
where isInit(); is
private static initialized = false;
public static boolean isInit()
{
return initialized;
}
where in your onCreate & on onDestroy functions you set the initialized variable accordingly.
or..u could just do if(SomeClass.this!=null) lol :S
/me stops writting wot

Thanks for the input everyone. I've realised the problem (but still can't fix it). I can call methods in other classes from my timer class.... but my main class that has the methods that I need implements OnClickListener (public class game extends Activity implements OnClickListener) so it is ONLY updating the view methods when something is clicked on. How should I go about fixing it so that I can call methods that will update when a timer calls them (e.g. I display the remaining time in the title bar and it doesn't update the current time UNLESS a button is clicked on)

Why not run the timer as a thread in the activity class itself?

Help writing something with setOnItemClickListener

In my Android app, I have a sound that I want to play when a certain selection has been made from a spinner, but I want it to play the when the user actually makes the proper selection (or just after). My problem is that although the sound does play when they make the correct selection, as long as that selection stays chosen, it also plays every time the app starts up, when it should ONLY play at the time it's chosen. I think I need to change my setOnItemSelectedListener to setOnItemClickListener, but I'm not sure how (still pretty new to java). Can any generous soul out there show me how to change this up (assuming that's how to best solve this problem)?
Here is the code I have now:
Code:
fitnessSpinner = (Spinner) findViewById(R.id.fitness_spinner);
ArrayAdapter adapter4 = ArrayAdapter.createFromResource(
this, R.array.fitness_array, android.R.layout.simple_spinner_item);
adapter4.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
fitnessSpinner.setAdapter(adapter4);
fitnessSpinner.setOnItemSelectedListener(new OnItemSelectedListener()
{
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long i) {
Log.d("test", "p: " + position + " " + i);
if(position == 0) {
//First Entry
MediaPlayer mp = MediaPlayer.create(mContext, R.raw.bowchica);
mp.start();
} if(position == 4) {
MediaPlayer mp = MediaPlayer.create(mContext, R.raw.debbie2);
mp.start();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});

I haven't try the below code but you can try it on your own and tell us.
In onCreate() declare MediaPlayer mp;
In every if statement that you use for check insert this code:
Code:
if(mp!=null){mp.release();}
int resid = R.raw.yoursound;
mp = MediaPlayer.create(this, resid);
After that override the methods onPause() and onResume() and insert this:
if(mp!=null){mp.release();}
If it is still playing a sound when you start your app, then you should check your code again if you have set as default option any of your selection options.

I would LOVE to try this out...Unfortunately, I'm way too dumb at this point point ot figure out exactly where those code snippets would go inside of what I already have.
Does anyone have a couple of minutes to show me where it would go?

Below is a sample code. Since i don't know your code I give you a snippet that you should adjust it to your code.
Code:
public class SampleSound extends Activity{
private Spinner fitnessSpinner;
private MediaPlayer mp;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);//here goes your layout
setViews();//here you will set all your views(spinners buttons textviews etc..)
setAdapters();//set your adapters here
setListeners();//
}
private void setListeners() {
fitnessSpinner.setOnItemSelectedListener(new OnItemSelectedListener(){
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long i) {
Log.d("test", "p: " + position + " " + i);
if(position == 0) {
//First Entry
if(mp!=null){mp.release();}
int resid = R.raw.bowchica;
mp = MediaPlayer.create(this, resid);
mp.start();
} if(position == 4) {
if(mp!=null){mp.release();}
int resid = R.raw.debbie2;
mp = MediaPlayer.create(this, resid);
mp.start();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}
private void setAdapters() {
ArrayAdapter adapter4 = ArrayAdapter.createFromResource(this, R.array.fitness_array, android.R.layout.simple_spinner_item);
adapter4.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
fitnessSpinner.setAdapter(adapter4);
}
private void setViews() {
fitnessSpinner = (Spinner) findViewById(R.id.fitness_spinner);
}
public void onResume(){
super.onResume();
if(mp!=null){mp.release();}
}
public void onPause(){
super.onPause();
if(mp!=null){mp.release();}
}
}

I really appreciate the help. I put the code in my routine, but it still plays the sound every time the activity is loaded (as long as the selection in the spinner is correct). It should only play the sound when the correct selection is made.
Any other ideas?

I am sure that your Spinner is set to some value (since you have values to display). Because your Spinner points to a selection (doesn't matter if you have selected or it is selected by default) your sound plays (even when you start the app).
A way to stop the sound playing at start is to declare and an other Item like you did with the previous 4 and set it as default selection of your Spinner.
To sum up:
1.You have to append in R.array.fitness_array an Item (like you did with the previous Items) and give it a name.
2.At the end of method setAdapters() insert this:
Code:
fitnessSpiner.setSelection(5);// or whatever is your selection number
Now it should work but you should know that this is not a good practice and you should try make a ListView or something else.

I'd be happy to change this out to a listview, or whatever would work. I just have to give my user a choice of 4 or 5 items, from which they can choose only one. Something like a drop down box, but in Android, I thought my only option was a spinner. But whatever I use, I have to be able to play a sound when certain items are chosen, but ONLY when those items are chosen, NOT whenever the activity is called up.
Any specific ideas of what I might change to?

What if I had another control like a textview or an edittext (with it's visibility property set to false) that I programatically populated with the users selection (when it's the selection that I want) and then have an OnItemClcickListener set to play the sound?
Could that work?

I will answer from the last to the top of your questions.
1.You can do whatever you want with android. You want TextViews and EditTexts with complex and nested Layouts you can do it. Write services that will communicate with your contacts through a content provider? You can do it.
Write, read and test code. Only this way you will actually learn.
2.Read developer.android.com. Read the android tutorials from there and specifically the Notepad example. You will learn a lot.
A good resource with small examples for ListViews is this.
3.Have you tried the changes I told you from the last post? Did it worked?
Since you just started with android and programming you must first be happy if you have the expected result and then read more to make your code better

Your suggested changes (fitnessSpiner.setSelection(5);// or whatever is your selection number) would stop the sound from playing, but defeat the apps purpose. Every time this activity is loaded, the spinners hit preferences to load the previously stored data. So if I force the spinner to a different selection to NOT play sound when the activity loads, then I would be displaying the wrong data for the user.

Yes you are right. So it is better to make a ListActivity. Read developer.android.com and the link i gave you before. You will be ok with this!

You're using "setOnItemSelectedListener", which sounds like when the app starts, its getting "selected" again.
Have you tried using "setOnItemClickListener" instead?
fitnessSpinner.setOnItemClickListener(new AdapterView.OnItemClickListener () {
public void onItemClicked() {}
};

onClickListener doesn't work for the spinner...I wish it did.
I REALLY need the drop down functionality of teh spinner, so I guess I'm going to try and figure out a way to have an invisible edittext that I set to the spinner selection and then use onClickListener or onChange...

Android/Java Newbie

Hi all, im having a go at developing a simple app. i have little experience with Java and Android development. i have a little test app at the moment and have created a new class, im trying to create a new instance of this class on a button click. it fails to do so, i cant for the life of me see why so.. can someone shed any light on this?
Thanks

I don't see anywhere in your code where you are calling the mainButton(View view) method. In the Android lifecycle, the onCreate method is the equivalent of a normal Java program's main() method, which means that code execution begins with the first line of onCreate(). Not knowing what you're trying to do, a good start would be to call your mainButton() method AFTER setContentView() in onCreate().
Side note: your mainButton() method has a View parameter that is never used. Is there a reason for that?
Android activity lifecycle: http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle

You have to use an intent on that button click, use the method onClickListener and define the intent in the androidmanifest.xml
e.g
Code:
Button button = (Button) findViewById(R.id.[B]button[/B]) // replace latter button with actual id defined in main xml.
button.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View arg0) {
// TODO Auto-generated method stub
startActivity(new Intent("[B]com.example.packagename.CLASSNAME[/B]")); // this should be your own package name.
}
});
Also define this in android manifest under the <application> and </application>
Code:
<activity
android:name=".[B]CLASSNAME[/B]"
android:label="@string/app_name"
>
<intent-filter>
<action android:name="[B]com.example.packagename.CLASSNAME[/B]" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Change the values of BOLD text according to your own values.
I tried to help you as far as I understood your question. Please let me know if you face any problem I would be more than happy to help you. Rest I am also in the learning phase so you can always PM me if you face any problem.

Nope! He didn't say that he wanted to launch a new Activity when the button is clicked. He wants to create a new instance of his LocationFactory Class.

Oops yeah right read that now...I thought he want to start an activity... Anyways tried to delete my reply but not getting an option to delete.

There are many flaws in his code. And the other thing is if its his first app and if he has low level of programming experience then according to me it would be a next to impossible app for him, as per his code and what he is trying to implement.
I think he should rather start up with small apps, understand things and then move on to complex apps.
P.S - its just my opinion

Agreed that he should start small...which is exactly why your suggestion for creating and handling Intents makes no sense. Before that, he should first understand the activity lifecycle. Until then, he can just stick to trivial single-activity apps to gain experience.
OP: This code should be placed in the onCreate method:
Code:
Button button = (Button) findViewById(R.id.your_button_ID_here)
button.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View arg0) {
mainButton(); // get rid of the View parameter in this method...it's not needed
}
});
This will cause a new instance of your LocationFactory to be created, and will also cause your Toast message to be displayed.

thanks for the replies. yes you are right in that i am inexperienced, but this is just a test app for me to play around with and learn on. i tend to learn better by doing rather than constantly reading. thanks for your suggestions ill look into them

I also believe in the same, I also keep on doing experiments and testing things out.
What I would suggest is that start with a small app and understand the insights on how android works and all...

Potential Solution
Alright, I think I've found your problem. Have a look at where you define your variables in your LocationManager class:
Code:
private static final Context Context = null;
Geocoder geocoder = new Geocoder(Context, Locale.getDefault());
LocationManager manager = (LocationManager) Context.getSystemService(android.content.Context.LOCATION_SERVICE);
This is your problem:
Code:
Context Context = null;
If your context is null, and you use it to create a geocoder and call Context.getSystemService, you'll hit a null pointer. You're trying to access an object (the Context) that doesn't even exist
I'd recommend you pass the context in the LocationManager constructor and then instantiate your objects there. That's standard java procedure.
Code:
private Context mContext = null;
Geocoder geocoder = null;
LocationManager manager = null;
public double Latitude = 0.0;
public double Longitude = 0.0;
public LocationFactory(Context context)
{
this.mContext = context;
this.geocoder = new Geocoder(context, Locale.getDefault());
this.manager = (LocationManager) Context.getSystemService(android.content.Context.LOCATION_SERVICE);
}
I also renamed Context to mContext - it's generally a good idea to keep the instance's name separate from the class name.
Try that - it should work. Please feel free to ask any more questions - this is how I learned, and I think it's the best way!

Is my Dialogbox correct?

Hey guys, im on the process of building my app. Basically, so far, this is what should happen:
The user presses a button and a dialogbox appears. In the dialogbox, the user selects the days in which the reminder shall remind him. (If that makes sense...).
This is my Java code:
Code:
package yCM.medireminder;
import java.util.ArrayList;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class ADD extends Activity implements OnClickListener{
private AlertDialog.Builder dialogBuilder;
private void days()
{
//Declaring the Variables
final ArrayList weekdays = new ArrayList();
dialogBuilder = new AlertDialog.Builder(this);
final String[] dayss = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};
//Starting the Process
dialogBuilder.setTitle("Check the Days");
dialogBuilder.setMessage("Check the days when you will shall be reminded");
dialogBuilder.setMultiChoiceItems(dayss, null, new DialogInterface.OnMultiChoiceClickListener() {
[user=439709]@override[/user]
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
// TODO Auto-generated method stub
if(isChecked){
weekdays.add(which);
}else if(weekdays.contains(which))
{
weekdays.remove(Integer.valueOf(which));
}
}
});
dialogBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
[user=439709]@override[/user]
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Your days have been set", Toast.LENGTH_LONG);
}
});
dialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
[user=439709]@override[/user]
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Your days have not been set", Toast.LENGTH_LONG);
}
});
// OUTPUT
AlertDialog dayDialog = dialogBuilder.create();
dayDialog.show();
}
Does everything look alright, the emulator isn't working for my and I have misplaced my phone (its on silent) so I have no way of checking whether it will work. I have linked the dialog box to a button so Im sure that when the button is clicked, the dialog box should appear.

It is recommended to use DialogFragments instead of simple dialogs. That way the system would orientation changes etc. for you.
However, you would need to convert your Activity into a FragmentActivity.

I do plan on making the app on permenantly on portrait mode so I don't think the orientation would be any problem even when the user switches to landscape.
Why would I need to convert my activity to fragmentactivity? What does this do? Also my min sdk is set to api level 8 (2.2 i believe).
Other than that, does the code seem alright?

You just need to do this if you want to use the DialogFragment. For the normal dialog you don't need it.
You can use fragments on Android 1.6+ if you include the supportv4 library.
Try it. That's all I can say. There might be other things that make it crash, apart from that code. Maybe related to the Android lifecycle.

thanks for the info. Just runned it, everythings working smooth for now. Any idea on how to make the android system recognise/link the days of the week on my string? I did have a read through this but didn't quite understand it. I have a feeling that I should be using something got to do with the calender though...

You can get the current time using
Code:
System.currentTimeMillis()
Then create a Date from it:
Code:
Date myDate = new Date(System.currentTimeMillis();
Then you can format it using the SimpleDateFormat class: http://developer.android.com/reference/java/text/SimpleDateFormat.html
For some things the Calendar class might be better: http://developer.android.com/reference/java/util/Calendar.html
However, I have not worked with it yet.

[Q] onSaveInstanceState

I'm new to android app development
Facing an issue:
Data (String values) lost while changing screen orientation
I googled about it and found it can be handled by onSaveInstanceState()
But didn't get how to use that in the java file
Can someone clear it to me?

static final String STATE_SCORE = "playerScore";
static final String STATE_LEVEL = "playerLevel";
...
@override
public void onSaveInstanceState(Bundle savedInstanceState) {
// Save the user's current game state
savedInstanceState.putInt(STATE_SCORE, mCurrentScore);
savedInstanceState.putInt(STATE_LEVEL, mCurrentLevel);
// Always call the superclass so it can save the view hierarchy state
super.onSaveInstanceState(savedInstanceState);
}
 @override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); // Always call the superclass first
// Check whether we're recreating a previously destroyed instance
if (savedInstanceState != null) {
// Restore value of members from saved state
mCurrentScore = savedInstanceState.getInt(STATE_SCORE);
mCurrentLevel = savedInstanceState.getInt(STATE_LEVEL);
} else {
// Probably initialize members with default values for a new instance
}
...
}

If It s so important then save it as file
Or save it as temporary data to Bundle
Code:
