Android Event Listeners

Question

I play with Android to find out the API, and I'm trying to code an action that can listen to changes in audio events. For example, when I press a button, I create a random ringtone. The text “Random Ringtone” is displayed on the button, but when you press the button, it says “Stop”, and pressing it, of course, stops playing the ringtone.

However, the problem is that when the melody stops playing by itself, the button still says “stop”.

I looked around to try to find an event listener that could listen when the melody stops playing, but I cannot find it. I saw some information about creating your own listeners, but I'm not interested in doing this (a bit advanced for me right now).

Is there an event listener of this type?

Answer 1

Maybe I'm wrong, but I think that the only audio class that triggers an event when it ends is the MediaPlayer class. Something like this should work ...

public class MyActivity extends Activity implements MediaPlayer.OnCompletionListener { MediaPlayer player = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); player = new MediaPlayer(); player.setOnCompletionListener(this); ... } @Override public void onCompletion(MediaPlayer mp) { // Called when playback is complete ... } }
