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?

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);
}
