介绍个第三方：
实现Android的全屏视频播放，支持完全自定义UI、手势修改进度和音量、hls、rtsp，设置http头信息，也能在ListView、ViewPager和ListView、ViewPager和Fragment等多重嵌套模式下全屏工作，占用空间非常小，不到60k。
本次是通过 SurfaceView + MediaPlayer 实现 横屏 全屏 播放。
//注意修改：
WindowFeature下的：Window.FEATURE_NO_TITLE, Window.FEATURE_INDETERMINATE_PROGRESS
Fullscreen
AndroidManifest.xml下activity节点添加android:screenOrientation="landscape"
1）通过 AudioManager 控制视频声音。
2）通过getWindow().getAttributes().screenBrightness 获取当前亮度，通过继承SimpleOnGestureListener手势监听onScroll，onSingleTapUp事件，
重新生成
1 WindowManager.LayoutParams lpa = getWindow().getAttributes();2 if (lpa.screenBrightness > 1.0f)3 lpa.screenBrightness = 1.0f;4 else if (lpa.screenBrightness < 0.01f)5 lpa.screenBrightness = 0.01f;6 7 getWindow().setAttributes(lpa);
3）activity oncreate 进行初始化 MediaPlayer， SurfaceView Holder
1 if (mediaPlayer == null) { 2 mediaPlayer = new MediaPlayer(); 3 // 不维持自身缓冲区，直接显示 4 // this value only use Hardware decoder before Android 2.3 5 if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB 6 && mHardwareDecoder) { 7 sv_videoplayer.getHolder().setType( 8 SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); 9 }10 sv_videoplayer.getHolder().setFixedSize(11 ScreenUtils.getScreenHeight(this),12 ScreenUtils.getScreenWidth(this));13 14 sv_videoplayer.getHolder().setFormat(PixelFormat.RGBA_8888);15 16 sv_videoplayer.getHolder().setKeepScreenOn(true);17 sv_videoplayer.getHolder().addCallback(new SurFaceCallback());18 } 4）调用 MediaPlayer 进行播放
1 mediaPlayer.reset();2 mediaPlayer.setDataSource(playUrl);3 mediaPlayer.setDisplay(sv_videoplayer.getHolder());4 // 缓冲5 mediaPlayer.prepareAsync();6 mediaPlayer7 .setOnBufferingUpdateListener(new BufferingUpdateListener());8 mediaPlayer.setOnPreparedListener(new PreparedListener(position));9 mediaPlayer.setOnCompletionListener(new CompletionListener());
5）在缓冲就绪初始化MediaController
1 /** 2 * //调用该方法,MediaPlayer就进入了"准备就绪" //状态,准备开始播放. //此处可用于动态设置SurfaceView的宽和高 3 * 4 */ 5 private final class PreparedListener implements OnPreparedListener { 6 private int position; 7 8 public PreparedListener(int position) { 9 this.position = position;10 }11 12 @Override13 public void onPrepared(MediaPlayer arg0) {14 // TODO Auto-generated method stub15 //MediaController进行设置和使用 16 mMediaController.setMediaPlayer(VideoPlayerActivity.this); 17 mMediaController.setAnchorView(findViewById(R.id.rl_video_player)); 18 mMediaController.setEnabled(true); 19 mMediaController.show(); 20 mediaPlayer.start();21 mProgressBar.setVisibility(View.GONE);22 mLoadRate.setVisibility(View.GONE);23 if (position > 0)24 mediaPlayer.seekTo(position);25 }26 27 } 6）显示缓冲百分比
1 private final class BufferingUpdateListener implements2 OnBufferingUpdateListener {3 4 @Override5 public void onBufferingUpdate(MediaPlayer arg0, int percent) {6 // TODO Auto-generated method stub7 mLoadRate.setText(percent + "%");8 }9 } 7）使用getHolder().addCallback(new SurFaceCallback())，继承Callback，
SurfaceView 所在Activity 离开了前台，SurfaceView会被destory。当Activity又重新
回到前台时，SurfaceView会被重新创建，SurfaceView是在onResume（）方法之后被创建。
防止视频过程中，电话来到，导致视频播放失败。
1 private final class SurFaceCallback implements Callback { 2 3 @Override 4 public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, 5 int arg3) { 6 7 } 8 9 @Override10 public void surfaceCreated(SurfaceHolder arg0) {11 if (mediaPlayer == null) {12 return;13 }14 if (playUrl != null && position > 0) {15 play(position);16 position = 0;17 }18 }19 20 @Override21 public void surfaceDestroyed(SurfaceHolder arg0) {22 if (mediaPlayer == null) {23 return;24 }25 if (mediaPlayer.isPlaying()) {26 mediaPlayer.stop();27 }28 }29 }
