Dismiss Android PopUpWindow object makes the status bar visible. How to stop this?

Question

I am having an Activity which is fullscreen. I am making the fullscreen activity using the below code (which I am calling in onResume method)

int currentApiVersion = Build.VERSION.SDK_INT;

    final int flags = 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;

    // This work only for android 4.4+
    if (currentApiVersion >= Build.VERSION_CODES.KITKAT) {
        activity.getWindow().getDecorView().setSystemUiVisibility(flags);
        // Code below is to handle presses of Volume up or Volume down.
        // Without this, after pressing volume buttons, the navigation bar will
        // show up and won't hide
        final View decorView = activity.getWindow().getDecorView();
        decorView.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
            @Override
            public void onSystemUiVisibilityChange(int visibility) {
                if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
                    decorView.setSystemUiVisibility(flags);
                }
            }
        });
    }

In this Activity, I am opening a PopUpWindow object. But after opening this, the status bar becomes visible. How to stop this ?

For showing the PopUpWindow, I am using the below code:

popupWindow = new PopupWindow(layout, RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT, true); popupWindow.showAtLocation(layout, Gravity.NO_GRAVITY, 0, 0);

I am not able to figure out, what is wrong in these methodology. Please help. Thanks in advance.

Change the way of Implementation and Apply this code in your onCreate on that Activity and make sure one thing you have added this before setContentView() in OnCreate

@Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

            setContentView(R.layout.splash_layout);
    }
