Answer 1

Try the following:

    getDialog().getWindow().getDecorView().setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);

Are you sure requireActivity().currentFocus isn't returning null? That seems to always happen when I try your code, and if it does it makes sense that it doesn't do anything. I'd suggest getting a view another way. As long as you're calling the function after you have returned from onCreateView you can just use view (from getView()):

val imm = requireActivity().getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(view?.windowToken, 0)
