title: BottomNavigationView overlapping FrameLayout in CoordinatorLayout
body: <p>The following is my layout xml. The problem now is that the BottomNavigationView is overlapping the FrameLayout. I wanted the FrameLayout to stretch to the top of the BottomNavigationView. </p>
  
  <p>I tried with trick such as adding paddingBottom in the FrameLayout but I wonder if there is other better solution. Thanks.</p>
