Android: MediaPlayer.setOnPreparedListener()

Question

I've got a Service, which implements MediaPlayer.OnPreparedListener.

Until now I called player.setOnPreparedListener(this) inside a function and it worked well. Now I want to call setOnPreparedListener from Runnable (using a Handler), but I get error :

The method setOnPreparedListener(MediaPlayer.OnPreparedListener) in the type MediaPlayer is not applicable for the arguments (new Runnable(){})

So instead of this I would need to use something that would point to current class. The question is, which class?

I assume that when you called player.setOnPreparedListener(this), your activity implemented MediaPlayer.OnPreparedListener. And your Runnable isn't (of course). There are two options:

If this runnable is implemented inside the activity, use the fully qualified this: YourActivity.this

If not, you can implement this listener in just the point of the call:

player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {
    // do stuff here
    }
}

Use

player.setOnPreparedListener(MyService.this);

In your Handler, this obviously refers to the Handler. By using MyService.this you force the this keyword a scope higher, referencing the Context of the Activity.

It should probably say "MyService.this", as it's a service that implements the listener, but yes, +1. – Martin Stone Feb 12 '12 at 09:57
No need to. If you don't know, you don't know ;) – nhaarman Feb 12 '12 at 10:16
