Video not taking full screen in landscape mode for some devices using videoview in android

Question

My videoview is working fine in portrait mode but in landscape it does not fit in full screen( i do not want to use layout-land). I am trying to change views programmatically but this is not working as expected. I tried to get the resolution of the device using below code:

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
WindowManager wm =(WindowManager)mContext.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
height = metrics.heightPixels 
width =  metrics.widthPixels

Testing on the devices with resolution 1080 * 1920 the value i am getting for height and width is 1080 and 1776 respectively. (For some devices I get correct values and videoview works fine in both orientations)

I am facing the same problem which has been asked in the below link-

Solved by using this code.

 RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.MATCH_PARENT,
                    RelativeLayout.LayoutParams.MATCH_PARENT
            );
    private void enterFullScreen(){
            this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
            mVideoView.setSystemUiVisibility(
                    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
            mVideoView.setLayoutParams(layoutParams);
        }

    private void exitFullScreen(){
              this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
                mVideoView.setSystemUiVisibility(0);
                isFullScreen = false;
                mFullScreen.setVisibility(View.INVISIBLE);
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
                    layoutParams.removeRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
                    layoutParams.removeRule(RelativeLayout.ALIGN_PARENT_TOP);
                    layoutParams.removeRule(RelativeLayout.ALIGN_PARENT_LEFT);
                    layoutParams.removeRule(RelativeLayout.ALIGN_PARENT_RIGHT);
                }else {
                    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM,0);
                    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP,0);
                    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT,0);
                    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT,0);
                }
                mFullScreen.setVisibility(View.VISIBLE);
        enter code here`enter code here`
                mVideoView.setLayoutParams(layoutParams);
            }
