title: Jetpack BottomNavigationView How to remove content fade in animation
body: <p>I'm creating a single activity applicatition. Inside Activity there is a <code>BottomNavigationView</code> 
  with <code>NavHostFragment</code>. Bottom navigation view comprise of multiple menu items. </p>
  
  <p>For easy to explain lets say there are three fragments <code>"FragmentOne"</code>, <code>"FragmentTwo"</code>, <code>"FragmentThree"</code></p>
  
  <p>each fragment have a different Toolbar. As a example <code>"FragmentOne"</code> is haveing a Toolbar with <code>CollapingToolbarLayout</code>, and <code>"FragmentTwo"</code> has a Normal Toolbar Design and <code>"FragmentThree"</code> has a toolbar with Image. </p>
  
  <p>I have included different design Toolbars in each fragment and the BottomNavigationView is inside Activity.</p>
  
  <p>Where select each bottom navigation menu, fragments are navigating correctly but content is showing fade in animation/transition.</p>
  
  <p>I have set the app theme as <code>Theme.AppCompat.Light.NoActionBar</code> So now since Toolbar is also inside the fragment content area <code>Toolbar</code> also showing fade in transition.I'm okay with content transition but Toolbar should stay Solid. </p>
  
  <p>Kindly help to me to solve this and feel free to request more information.</p>
