Fading Actionbar

This is a quick example of how to create a fading actionbar effect like this in Appcelerator Titanium

How this works

This is actually very simple. The trick is putting the Actionbar in overlay mode by configuring the theme with windowActionBarOverlay:true. Then all you need to do is updating the color of the Actionbar, in this case by scrolling a ScrollView.
