title: Custom Notification View
body: <p>I would like to create a notification icon view that looks similar to the Google+ app's notification. The difference will be that I need to be able to change the color at runtime where as the Google+ icons gray or red so I'm assuming they are using a StateListDrawable.</p>
  
  <p>What is the best approach for this? I'd prefer to have the rounded clipped corners and have the option to have a drawable inside. This custom view will be placed in the Action Bar as well. I still need the view to respond to android:background state list drawables so I can have the click and selected accordance working.</p>
  
  <p>This custom view will be placed in the action bar as well.</p>
