title: EditText not showing under Ice Cream Sandwich
body: <p>I have a EditText in a layout with a white background.
  On Android 2.x, the EditText is visible with a frame around it, but in Ice Cream Sandwich on a Galaxy Nexus, it is not visible until I click on it. Then the blue line under it appears.</p>
  
  <p>I think this is due to the holo theme in Ice Cream Sandwich, but can I somehow get the line to show all the time? Or do I have to add a custom background 9patch-image?</p>
  
  <p>I am using ActionBarSherlock for compatibility, but I don't think this is an issue here, as the EditText is shown normally on older Versions.</p>
  
  <p>Regards,
  Kim</p>
