title: Android overlay a view ontop of everything?
body: <p>Can you overlay a view on top of everything in android?</p>
  
  <p>In iPhone I would get the new view set its <code>frame.origin</code> to (0,0) and its width and height to the width and height of <code>self.view</code>. Adding it to <code>self.view</code> would then cause it to act as an overlay, covering the content behind (or if it had a transparent background then showing the view behind).</p>
  
  <p>Is there a similar technique in android? I realise that the views are slightly different (there are three types (or more...) relativelayout, linearlayout and framelayout) but is there any way to just overlay a view on top of everything indiscriminately?</p>
