java - MediaPlayer 没有在每个按钮同时单击时播放音频

Question

我正在使用 MediaPlayer 播放字母表。单击单个按钮时正在播放音频。每次按钮点击均不负有责任。当音频结束时，然后使用另一个按钮。但我想设置每个按钮同时单击播放音频。这个怎么做？请告诉我如何解决这个问题。

        stopPlayer();
    }

}

希望我能从这里得到帮助。我只想播放语音，同时点击彼此的按钮。

在初始化新音频或媒体之前，请在您的中调用此方法

public void sorea (View v)
{
    Button button = (Button)findViewById(R.id.Sorea);
    final Animation myAnim = AnimationUtils.loadAnimation(this, R.anim.bounce);
    button.startAnimation(myAnim);
    if (player == null){

  //Call the StopPlaying() to release player
  stopPlaying();
  player = MediaPlayer.create(this, R.raw.sorea);
  player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                stopPlayer();
            }
        });
    }
    player.start();
}

 private void stopPlaying() {
        if (player != null) {
            player.stop();
            player.release();
            player= null;
       }
    }
