title: Specifying imageView to resize as percentage of screen
body: <p>In Android I need to have a simple layout to be designed using XML layout (rather than programming):</p>
  
  <p>I need to have the following :</p>
  
  <p>1- small image view on the left (centered vertically)</p>
  
  <p>2- Three image views a bit larger beside each others (also centered vertically)</p>
  
  <p>3- Small image view on the right side (centered vertically)</p>
  
  <p>so the 5 images are adjacent horizontally and centered vertically. </p>
  
  <p>This is simple, anyhow the question is how to specify the image views to resize as percentage of the screen height ? </p>
  
  <p>So if I specify the three image items to be 60% of screen height, I expect the imageView to resize (including the source image) to be 60% of screen height.</p>
  
  <p>Is it achievable? </p>
  
  <p>Thanks</p>
