ListView background tuning: Android graphical performance (google io 2013)

Developer options

If you set own background color on ListView, the android redraw once since android draw windowBackground first.
So, if you move android:background of ListView to style windowBackground, you can reduce one overdraw.

<style name="AppTheme" parent="android:Theme.Light">
<item name="android:windowBackground">@color/dark/background</item>
</style>
