title: how to change the size of design xml screen size in Android studio?
body: <p>so I am trying to use scroll view, and there is a lot of views that will be nested  in my scroll view.</p>
  
  <p>so I want to adjust it in the design tab xml not in the text tab xml using constraint layout, it will be great if I can set and see it in the designer xml tab.</p>
  
  <p>in iOS development I can change the height of 'canvas' design screen like the image below, the screen 'canvas' on the left is higher than the screen canvas on the right side, so I can set the constraint and see all the views in the design before running the app.</p>
