title: Defining Z order of views of RelativeLayout in Android
body: <p>I would like to define the z order of the views of a RelativeLayout in Android.</p>
  
  <p>I know one way of doing this is calling <code>bringToFront</code>.</p>
  
  <p>Is there are better way of doing this? It would be great if I could define the z order in the layout xml.</p>
