Android Soundboard only one sound at a time

Question

I am trying to write an Android Soundboard with multiple buttons. Each button should play a different sound.

I have a OnClickListener on each button:

    buttonAlan.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            playSound("alan");
        }
    });

Each of these buttons is calling the following function.

private void playSound(String sound) {

    int path = getResources().getIdentifier(sound, "raw", getPackageName());
    mediaplayer = MediaPlayer.create(this, path);


    try {
        mediaplayer.prepare();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    mediaplayer.start();
}

The soundboard works, but everytime you click a button it plays the sound over and over again. I need the mediaplayer to stop playing, but everytime I write something like mediaplayer.stop(), the App won't work at all. Any suggestions what I should change in my function/code?

Answer 1

i solved it using a soundpool, there you can also play multiple sounds at the same time. i first initialize it and load sounds i need in the constructor

SoundPool soundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
int gameOverSound = soundPool.load(context, R.raw.gameover, 1);

and then you can play it like this:

public void playSound(int soundId) {
      soundPool.play(soundId, 1.0f, 1.0f, 0, 0, 1);
}

edit: regarding the mediaplayer you have to call stop() and release() before you start playing another sound. also you can set

mPlayer.setLooping(false);
