Question

我已经实现了媒体播放器控制器。问题是，从用户控件可见的媒体播放器活动转移到之前的活动时，会发生Window泄漏错误。此外，在添加媒体控制器时，后退按钮也会变为禁用。此错误发生在bestAudioController.show（）的第70行;

 public void playAudio() {

    bestService.playSong();

   bestAudioController.show();

}

这行playAudio（）

   private ServiceConnection mServiceConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName componentName, IBinder 
             iBinder) {
        Log.e("onServiceConnected,","MAINACTIVITY");
        bestService = ((BestService.MyBinder) iBinder).getService();
        isBound = true;

         LocalBroadcastManager.getInstance(getApplicationContext()).
          registerReceiver(onPrepareReceiver,      
                new IntentFilter("MEDIA_PLAYER_PREPARED"));

      playAudio();
    }

    @Override
    public void onServiceDisconnected(ComponentName componentName) {
        Log.e("onServiceDisconnected","MAINACTIVITY");
        isBound = false;
    }
};

错误日志显示以下内容

我用来解决此问题的解决方案是在dismiss()之前的对话框上调用hide()，以确保在转到其他活动之前完全删除对话框。

 ...
 progressDialog.dismiss();
 progressDialog.hide();
 ...
