=====================================android

在使用surfaceView和MediaPlayer播放视频的时候出现了一个异常，纠结了好久，通过同事帮助，终于发现了问题的根源。ide

异常以下：this

E/AndroidRuntime( 1765): Caused by: java.lang.IllegalArgumentException: The surface has been released
E/AndroidRuntime( 1765):     at android.media.MediaPlayer._setVideoSurface(Native Method)
E/AndroidRuntime( 1765):     at android.media.MediaPlayer.setDisplay(MediaPlayer.java:633)视频

缘由是在surfaceHolder还没准备好的时候，我就调用了MediaPlayer的start()方法。blog

正确的播放流程应该是：get

        surfaceView = (SurfaceView) findViewById(R.id.PlaySurfaceView);
        surfaceHolder = surfaceView.getHolder();
        surfaceHolder.addCallback(this);it

      mediaPlayer.setDisplay(surfaceHolder);io

try {
            
            mediaPlayer.setDataSource(this, Uri.parse("/sdcard/bianxing.ts"));
            
        } catch (IllegalArgumentException e1) {
            e1.printStackTrace();
        } catch (SecurityException e1) {
            e1.printStackTrace();
        } catch (IllegalStateException e1) {
            e1.printStackTrace();
        } catch (IOException e1) {
            e1.printStackTrace();
        }
        
        try {
            mediaPlayer.prepare();
        } catch (IllegalStateException e1) {
            e1.printStackTrace();
        } catch (IOException e1) {
            e1.printStackTrace();
        }
        
        mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
            
            @Override
            public void onPrepared(MediaPlayer mp) {
                
                mediaPlayer.start();
                
            }
        });扩展

这样就能够正常播放了，唉，不容易啊，感谢同事的帮助。

其实对Medialayer的封装来讲，VideoView已经作的很好了，本身再写这些确实费力，指望之后扩展会好点
