title: Gradient styles
body: <p>In my Android application I've hidden the default title bar, introduced a TabView and added my own titlebar under that TabView's tabs.  At the moment, I'm using the ?android:attr/windowTitleStyle style which makes my new titlebar look gray and gradient.  It looks pretty good, but my screens are looking pretty grayscale.  I'd like to spice things up a bit by making this titlebar a different color gradient.</p>
  
  <p>What am I looking at here?  Creating my own image and using it?  The ?android:attr/windowTitleStyle style seems to expand depending on the height of your custom titlebar; so I'm not sure it's actually a single image.</p>
  
  <p>I've attempted to throw a LinearLayout over it with a bit of translucency (ex: making the color #800000FF), but the gradient style I have behind this LinearLayout disappears.</p>
  
  <p>Thanks for your help</p>
  
  <p>Update:</p>
  
  <p>Per my answer down below, I've figured out that I can create an XML file that defines a gradient and use that.  It works fine inside a LinearLayout (titlebar_gradient) I have on my layout.  However, it is not working on the outer-most LinearLayout (background_gradient).  Could someone tell me why?  As I understand it, the ListView should be transparent...</p>
