title: Why the content in the layout designer does not fit the emulator?
body: <p>I used the Android Studio design layout editor having gridLayout within the RelativeLayout, added 4 buttons horizontally. It appears fine in the Android Studio layout designer but when I ran it in the virtual emulator or a Samsung phone not all the buttons fit in the screen.
  How do you make it work for all android phones? 
  Is it not WYSIWYG?</p>
