深圳B2C网站建设没广告的视频播放器app

从网上看了很多资料，发现好多都是错误的，所以今天特意更新这个问题的原因，
在播放mediaPlayer.start()时SurfaceHolder没有来的及调用onCreate()方法创建view，导致holder没有成功加载，因为mediaplayer是在SurfaceHolder上面播放的，所以才抛出播放异常。贴出正确代码

 mSurfaceView = (SurfaceView) findViewById(R.id.surface_view);AssetManager assetManager = getAssets();try {mDescriptor = assetManager.openFd("test1.mp4");} catch (IOException e) {e.printStackTrace();}mediaPlayer = new MediaPlayer();mSurfaceView.getHolder().addCallback(new SurfaceHolder.Callback() {@Overridepublic void surfaceCreated(SurfaceHolder holder) {Log.d(TAG, "surfaceCreated=" + System.currentTimeMillis());try {mediaPlayer.setDataSource(mDescriptor.getFileDescriptor(), mDescriptor.getStartOffset(), mDescriptor.getLength());mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);//设置播放声音类型mediaPlayer.prepare();mediaPlayer.setDisplay(mSurfaceView.getHolder());} catch (IOException e) {e.printStackTrace();}}@Overridepublic void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {Log.d(TAG, "surfaceChanged=" + System.currentTimeMillis());}@Overridepublic void surfaceDestroyed(SurfaceHolder holder) {Log.d(TAG, "surfaceDestroyed=" + System.currentTimeMillis());}});mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {@Overridepublic void onPrepared(MediaPlayer mp) {Log.d(TAG, "onPrepared=" + System.currentTimeMillis());mediaPlayer.start();}});mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {@Overridepublic void onCompletion(MediaPlayer mp) {Log.d(TAG, " times onCompletion=" + System.currentTimeMillis());mediaPlayer.release();}});}

medialplayer播放的生命周期：

surfaceCreated—-SurfaceHolder被创建，只要在SurfaceHolder被创建的时候做设置就可以避免The surface has been released问题。
surfaceChanged——SurfaceHolder发生改变
onPrepared—-mediaPlayer准备ok
onCompletion—–mediaPlayer播放完成
surfaceDestroyed—–SurfaceHolder被销毁。
有什么问题请各位指出，谢谢！
