從網(wǎng)上看了很多資料，發(fā)現(xiàn)好多都是錯誤的，所以今天特意更新這個問題的原因，
在播放mediaPlayer.start()時SurfaceHolder沒有來的及調(diào)用onCreate()方法創(chuàng)建view，導(dǎo)致holder沒有成功加載，因?yàn)閙ediaplayer是在SurfaceHolder上面播放的，所以才拋出播放異常。貼出正確代碼

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);//設(shè)置播放聲音類型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被創(chuàng)建，只要在SurfaceHolder被創(chuàng)建的時候做設(shè)置就可以避免The surface has been released問題。
surfaceChanged——SurfaceHolder發(fā)生改變
onPrepared—-mediaPlayer準(zhǔn)備ok
onCompletion—–mediaPlayer播放完成
surfaceDestroyed—–SurfaceHolder被銷毀。
有什么問題請各位指出，謝謝！
