本文探讨了MediaPlayer在设置循环播放后不触发onCompletion回调的问题，并提供了详细的伪代码示例，展示了如何正确处理视频播放结束后的逻辑，包括下一视频的自动播放。

mediaPlayer播放完成后不走回调，检查下是否设置了mediaPlayer.setLooping(true);
设置循环播放就不会走onCompletion回调。

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) {

        }
    }
