title: How can I set the map view to full screen with bottom navigation bar
body: <p>I want to set the mapview to full screen, I had done every necessary things like setting both the framelayout and the mapview to matchparent but still when i run the app on my phone only a portion(maybe 60dp is the height but the width is fullscreen) of map was visible.</p>
  
  <p>Here are some of my layout xml file.</p>
  
  <p>//// for the fragment map ///////////</p>
  
  <pre><code>&lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      tools:context=".MapFragment"&gt;
  
      &lt;fragment

          android:layout_width="match_parent"
