title: How to pull random image within layout xml?
body: <p>Within my layout xml file I would like the 'android:src=""' to pull a random image from a 'bg' folder within drawable.</p>
  
  <p>I know this can be done pragmatically but I'd like to keep it within the layout files.</p>
  
  <p>Is there any way to create an array of everything in the bg folder and pull from it from within the layout xml?</p>
