title: Progess bar not shown on Drawer Layout
body: <p>I can't find Progress bar in the Drawer layout. Change the position but not visible. I need the layout to be Drawer Layout only and can't be changed.
  Help with some changes needed to make the progress bar visible.
  The Progress bar must be visible to the user while webview is loading.</p>
  
  <p>Below is my XML file for the layout</p>
