Android如何完美删除MediaPlayer

我正在尝试开发一个简单的测试项目，当我点击按钮时播放声音，并在播放声音几分钟后自动停止

以下是一段代码片段：

播放代码：

if (mPlayer != null) mPlayer = null;

mPlayer = MediaPlayer.create(this, R.raw.shush_v2);

mPlayer.setLooping(true);

mPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
     @Override
     public void onPrepared(MediaPlayer mediaPlayer) {
          mediaPlayer.start();
     }
});

if(mPlayer != null && mPlayer.isPlaying()) {               
     mPlayer.stop();

     mPlayer.reset();

     mPlayer.release();

     mPlayer = null;
}

停止代码：

if (mPlayer != null) mPlayer = null;

mPlayer = MediaPlayer.create(this, R.raw.shush_v2);

mPlayer.setLooping(true);

mPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
     @Override
     public void onPrepared(MediaPlayer mediaPlayer) {
          mediaPlayer.start();
     }
});

if(mPlayer != null && mPlayer.isPlaying()) {               
     mPlayer.stop();

     mPlayer.reset();

     mPlayer.release();

     mPlayer = null;
}

但有时我在停止声音后仍能听到两种声音

以前见过这种行为吗？

您应该清除媒体播放器

public class PlayerApp extends Activity {
    Button btnStart;
    MediaPlayer mediaPlayer = null;

    // Use the handler to stop the Player, after specific time
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_player_app);
        btnStart = (Button)findViewById(R.id.btnStart);
        btnStart.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view)
            {
                // Initialize Player and start it.
                // Call the Handler same time.
                mediaPlayer = MediaPlayer.create(getApplicationContext(), R.raw.test);
                mediaPlayer.start();
                startHandler();
            }
        });
    }
    private void startHandler()
    {
        final Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                // if Player is not null, then Stop it and Reset Null.
                if(mediaPlayer!=null)
                {
                    mediaPlayer.stop();
                    mediaPlayer = null;

                }
            }
        }, 2500);
    }

}

  //example usage of clearing media player when its over.
  ourSong.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    public void onCompletion(MediaPlayer mp) {
        clearMediaPlayer(mp);
    }
  });
  //You can use this to stop media player.
  private void clearMediaPlayer(MediaPlayer mp){
    if(mp!=null){
          mp.stop();
          mp.release();// this will clear memory
          mp = null;
    }
  }

嗨，贾斯普里特，我检查了你的答案，并尝试了一下，但这里同样是我的全部代码。
