android阿里云点播无法响应OnCompletionListener

下面是我的伪代码

private void playVideo() { //如果不为空释放在new if (mediaPlayer != null) { mediaPlayer.reset(); } mediaPlayer = new MediaPlayer(); try { mediaPlayer.setDataSource(getContext(), Uri.parse(videoUrl)); if (mSurfaceView.getVisibility() == View.GONE) mSurfaceView.setVisibility(View.VISIBLE); SurfaceHolder holder = mSurfaceView.getHolder(); holder.addCallback(new MyCallBack()); mediaPlayer.prepare(); //准备完成监听 mediaPlayer.setOnPreparedListener(onPreparedListener); mediaPlayer.setOnCompletionListener(onCompletionListener); } catch (Exception e) { e.printStackTrace(); } }

/**
 * 准备完成
 */
MediaPlayer.OnPreparedListener onPreparedListener = new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {

// mediaPlayer.setLooping(true);//循环播放 mp.start(); } };

MediaPlayer.OnCompletionListener onCompletionListener = new MediaPlayer.OnCompletionListener() {
    @Override
    public void onCompletion(MediaPlayer mp) {
        XLogUtils.e("播放完成");
        mSurfaceView.setVisibility(View.GONE);
        if (currentVideoIndex == videoUrls.size() - 1) return;
        currentVideoIndex++;
        videoUrl = videoUrls.get(currentVideoIndex);
        XLogUtils.d("播放下一个");
        playVideo();
    }
};

/**
 *
 */
private class MyCallBack implements SurfaceHolder.Callback {
    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        if (mediaPlayer != null)
            mediaPlayer.setDisplay(holder);
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {

    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {

    }
}
