卡住後如何使活動停止播放鈴聲

我是一個noob，我在停止我的應用程序中的音樂時遇到問題，它會在關閉應用程序後繼續播放很長時間。繼承人一些代碼，我希望有人可以幫助！以下是我需要幫助的部分，其餘代碼有效。卡住後如何使活動停止播放鈴聲

你試過重寫'onPause'，'你的活動onDestroy'和禁用/在那裏卸下球員？ – 2012-03-07 03:34:31

我會在那裏放？我已經嘗試在我的活動底部放置一個onDestroy，但它不起作用。我有上面的更新代碼，如果你可以檢查它會很好 – nlitech 2012-03-07 14:24:04

//Give path of your media file 

     String path=""; 

      MediaPlayer Uri myUri = Uri.parse(audPath[songIndex]); 

     mp=new MediaPlayer(); 
      mp.setLooping(false); 
     mp = MediaPlayer.create(ActivityName.this, myUri); 

     mp.start(); 



     //stop music file on completion 
     mp.setOnCompletionListener(new OnCompletionListener() { 

          @Override 
          public void onCompletion(MediaPlayer mp) { 
           // TODO Auto-generated method stub 
           mp.stop(); 
           mp.release(); 
          } 
         });
