title: Android studio does not show status bar, navigation bar & default toolbar in layout preview
body: <p>I am using the updated version of Android Studio.<br />
  In the previous version, the design view was just like the image(left side). But now I am missing all of these top and bottom view (right side of the image). Do I need to install plugins or what should I do to get a proper view of the left side image?</p>
  <p>The left image shows the correct view, the Right side is the preview from the updated Android Studio.<br />
