VideoView双击横屏全屏实现

效果如图：

实现步骤：

1.给videoview添加ontouch监听，this是所在的activity：

videoView.setOnTouchListener(this);

2.重写ontouch方法：

@Override
    public boolean onTouch(View v, MotionEvent event) {
        if(v.getId() == R.id.video_view) {
            return mGesDetector.onTouchEvent(event);
        }
        return super.onTouchEvent(event);
    }

3.写一个内部类实现

GestureDetector.SimpleOnGestureListener

接口：

/*
    *
    * 手势监听类
    * */
    class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
        public MyGestureListener() {
            super();
        }
        @Override
        public boolean onDoubleTap(MotionEvent e) {
            if (screenState == LAND_SCREEN) {
                convertToPortScreen();
            } else if (screenState == PORT_SCREEN) {
                convertToLandScreen();
            }
            return true;
        }
}

4.使用手势监听类：

private GestureDetector mGesDetector;
mGesDetector = new GestureDetector(this,new MyGestureListener());
mGesDetector.setOnDoubleTapListener(new MyGestureListener());

走完这四步，对videoview的双击事件监听已经写完了。接下来奉上横竖屏切换的代码：

private void convertToPortScreen(){
        getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);//设置videoView竖屏播放
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, ToolUtils.dip2px(StudyWithExerciseActivity.this, 198f));
        params.setMargins(ToolUtils.dip2px(StudyWithExerciseActivity.this,12),ToolUtils.dip2px(StudyWithExerciseActivity.this,15),
                ToolUtils.dip2px(StudyWithExerciseActivity.this,12),ToolUtils.dip2px(StudyWithExerciseActivity.this,14));
        //params.addRule(RelativeLayout.CENTER_IN_PARENT);
        videoView.setLayoutParams(params);
        screenState = PORT_SCREEN;
    }

以上是切换成竖屏时走的代码。

private void convertToLandScreen(){
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);//设置videoView全屏播放
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//设置videoView横屏播放
        WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
        android.view.Display display = wm.getDefaultDisplay();
        Point point = new Point();
        int API_LEVEL = android.os.Build.VERSION.SDK_INT;
        if(API_LEVEL >= 17){
            display.getRealSize(point);
        }else{
            display.getSize(point);
        }
        int height = point.y;
        int width = point.x;
        Log.i(TAG,"screenHeight = "+height+" ; screenWidth = "+width);
        RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) videoView
                .getLayoutParams(); // 取控当前的布局参数
        layoutParams.height = height;
        layoutParams.width = width;
        layoutParams.setMargins(0,0,0,0);
        videoView.setLayoutParams(layoutParams);

        screenState = LAND_SCREEN;
    }

以上为切换成横屏时走的代码。

注意：清单文件中要在该activity的便签中加入

android:configChanges="orientation|screenSize|keyboardHidden"

否则会报错。

好了，到这里VideoView双击全屏的效果就实现了。如果实际应用中遇到什么问题给我留言，会尽快回复。
