AppBar not hiding completely in status bar when scrolling

Question

I am trying to implement a search bar (like in GDrive or Keep Notes) with an AppBar layout, so when you scroll up it disappears from the screen, scrolls down to appear. Also, I make the status bar transparent in my style.xml file. But when I scroll up, AppBar not hiding completely, so you can see its bottom in the status bar. How can I fix this to hide it completely from the screen?

You have told the statusbar to be ```translucent``` which makes it partially transparent. Try removing that and setting a solid color. — private static, Dec 21 '20 at 17:31
@PrinceAli, but I want the status bar to be `translucent` and at the same AppBar need to be hidden from the screen — copycat13, Dec 21 '20 at 18:33
@LucaPizzini, hide the search bar which is a child of AppBar — copycat13, Dec 21 '20 at 18:34
Can you post the code that you use to translate the search bar up? — lpizzinidev, Dec 22 '20 at 07:45
@LucaPizzini, the main attribute to translate the search bar up is `app:layout_scrollFlags="scroll|enterAlways|snap"` of LineralLayout from code above. You can read more about AppBar on the material design site [here](https://material.io/components/app-bars-top/android) — copycat13, Dec 22 '20 at 13:31

My problem was solved programmatically by so (original answer):

// In Activity's onCreate() for instance
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    Window w = getWindow();
    w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
