title: Views in container doesn't show with the Navigation Drawer
body: <p>I have a DrawerLayout here that works perfeclty on API 21 and higher but when I am on KitKat and lower versions, the "buttonMenu" doesn't show.
  "buttonMenu" allows the user to open and close the drawer. </p>
  
  <p>Thank you for your help.</p>
