android Navigation Bar hiding and persantage of usable screen overlap

My problem is about persantage of usable screen . My application working well normally but ı assume that if ı change dimension of screen (for example galaxy s8+) it is down.

this is how is working fine

enter image description here strong text

and this is the wrong one

enter image description here

the problem related with NavigationBar. I tried to set MACHPARENT params and normally I use programmatically DisplayMetrics metrics = this.getResources().getDisplayMetrics(); width = metrics.widthPixels; height = metrics.heightPixels - Utils.getStatusBarHeight(getContext()); this code. But it is not working in Galaxy s8+ when I hide navigationBar. Does anyone can help me what is my fold?

edit. I mean height of my screen doesnt work.

I had the same problem and could solve this with the decorview:

    //Get the correct screen size even if the device has a hideable navigation bar (e.g. the Samsung Galaxy S8)
    View decorView = getWindow().getDecorView(); //if you use this in a fragment, use getActivity before getWindow()
    Rect r = new Rect();
    decorView.getWindowVisibleDisplayFrame(r);
    int screenHeight = r.bottom; // =2220 on S8 with hidden NavBar and =2076 with enabled NavBar
    int screenWidth = r.right; // =1080 on S8
