title: The background distortion when the screen turn from vertical to horizontal?
body: <p>In my fragment , I set the background to a <code>Relativelayout</code>.</p>
  
  <p>But when the screen turn from vertical (Portrait) to horizontal (Landscape) , the background image seems like distorted.</p>
  
  <p>It can not set <code>scaleType</code> to <code>Relativelayout</code>.</p>
  
  <p>Does there has any method can make the background auto scaling when the screen turn from vertical to horizontal?</p>
  
  <p>(Does not need to detect the screen size , just let the background image auto scaling and no distortion)</p>
  
  <p>Thanks in advance!</p>
