在软键盘出现时出现状态栏但在沉浸模式下软键盘消失时不会隐藏

Question

Initially I set my Activity to be in Immersive Mode with the following code:

View decorView = getWindow().getDecorView();
decorView.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);

Everything works fine until the user clicks on an EditText and the soft keyboard appears. It causes the Status Bar to stick on the top and never hides back again even after the soft keyboard disappears. Strangely enough, I only encounter this problem on LG/Samsung phones, Sony phones do not have any problem with this. Anyone has any idea about this?

Use immersive mode like this.

@Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        immersiveMode();
        getWindow().getDecorView().setOnSystemUiVisibilityChangeListener
            (new View.OnSystemUiVisibilityChangeListener() {
                @Override
                public void onSystemUiVisibilityChange(int visibility) {
                    immersiveMode();
                }
            });
    }

Here is your immersive mode function.

public void immersiveMode() {
        final View decorView = getWindow().getDecorView();
        decorView.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);
              }

Also call immersiveMode() in OnResume() ; Now status bar will disappear as your soft key board disappears.

Here is my solution for this ; First I checked if soft keyboard is showed up or not:

getWindow().getDecorView().getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {

            Rect r = new Rect();
            getWindow().getDecorView().getWindowVisibleDisplayFrame(r);
            int screenHeight = getWindow().getDecorView().getRootView().getHeight();

            int keypadHeight = screenHeight - r.bottom;

            //Log.d(TAG, "keypadHeight = " + keypadHeight);

            if (keypadHeight > screenHeight * 0.15) { 
                 //Keyboard is opened
                 hideNavBar();
            }
            else {
                // keyboard is closed
            }
        }
    });

And I have a hideNavBar() method to be triggered when soft keyboard is showed up.

private void hideNavBar() {
if (Build.VERSION.SDK_INT >= 19) {
    View v = getWindow().getDecorView();
    v.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);
}

}

This solves the problem of getting navigation bar while there is an Edittext to be typed.
