推荐答案

您必须使用处理程序。

试试这个

in your onCreate use this 

  //start media player
  mp.start();


  mTimer.sendMessageDelayed(new Message(),5*10000);

创建一个类你活动类

create a class in you activity class as

    private MusicTimer mTimer = new MusicTimer();

    private class MusicTimer extends Handler
    {
       @Override
       handleMessage(Message msg)
       {
           onTimerExpire();
       }  



        public void onTimerExpire()
        {
           //stop player here
        }

}

请媒体播放器对象的成员变量，这将播放五Seconde系列则停止n该

make media player object member variable this will play that for five seconde then stop nthat
