我正在制作一个音板，我有大约12个媒体播放器，当我在我的模拟器中启动应用程序时，我开始点击一些按钮，其他没有点击的按钮停止产生他们准备制作的声音。

我建议你只使用一个媒体播放器：
MediaPlayer mp;
然后，在onCreate方法中：
mp.setOnPreparedListener(new OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
在你的onClick听众身上：
mp.setDataSource(this,R.raw.gunshot);
mp.prepareAsync();
