.MP3播放的MediaPlayer使用只有一個時間，而不是循環

Question

所以我有一個.mp3 in資產的文件夾（我打算以後有更多），我有相關的發揮它的簡單點擊：

public static MediaPlayer m = new MediaPlayer(); 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    Button button= (Button) findViewById(R.id.btnDrum); 
    button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      try { 
       PlayMusic(v); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
    }); 

} 

private void PlayMusic(View v) throws IOException { 
    try { 
     if (m.isPlaying()) { 
      m.stop(); 
      m.release(); 
      m = new MediaPlayer(); 
     } 

     AssetFileDescriptor descriptor = getAssets().openFd(Kit.KickDrum); 
     m.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength()); 
     descriptor.close(); 

     m.prepare(); 
     m.setVolume(1f, 1f); 
     m.setLooping(true); 
     m.start(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 

然而，每次我嘗試點擊按鈕，我都在循環播放音樂！我只需要它來玩一次，並停止！如何才能做到這一點？

謝謝！

Answer 1

要設置它使用m.setLooping(true);其更改爲假

Answer 2

試試這個代碼循環

try { 
      Uri mp3 = Uri.parse("url"); 
      mediaPlayer = new MediaPlayer(); 
      mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); 
      mediaPlayer.setDataSource(context, mp3); 
      mediaPlayer.prepare(); // might take long! (for buffering, etc) 
      mediaPlayer.start(); 
      mediaPlayer.setOnCompletionListener(onCompletionListener); 
     } catch (IllegalArgumentException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (SecurityException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (IllegalStateException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 

// onCompletionListerner

private OnCompletionListener onCompletionListener = new OnCompletionListener() { 

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