解决JCVideoPlayer视频全屏不能播放问题！

在manifest里配置

这是播放视频的Activity
 <activity
            android:name=".Activity.ParticularsActyvity"
            android:configChanges="orientation|screenSize|keyboardHidden"
            android:screenOrientation="portrait"
            />
            

在它的点击事件里

 activityPredictionPopwindowBack.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        popupWindow.dismiss();

                        //----
                        DisplayMetrics displayMetrics = new DisplayMetrics();
                        getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
                        int width = displayMetrics.widthPixels;
                        int heisht = displayMetrics.heightPixels;
                        if (width<heisht){
                            JCVideoPlayer.releaseAllVideos();
                        }
                    }
                });

  JCVideoPlayer.FULLSCREEN_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;  //横向
                JCVideoPlayer.NORMAL_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT;  //纵向

重写Activity方法

 @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        int width = dm.widthPixels;
        int height = dm.heightPixels;
        if (height<width) {
            popupWindow.dismiss();

        }else {
            popupWindow.showAtLocation(predictionview,Gravity.CENTER, 0, 0);
//            JZVideoPlayer.releaseAllVideos();
        }

    }
