Position view below action bar with overlay

Question

I would like to position a view below an action bar with overlay. Is there a way of doing this via XML layout?

I would like to avoid using constants as there are already at least 4 possible values and that number is likely to grow.

Compatibility with ActionBarSherlock is a plus.

Answer 1

android:layout_marginTop="?attr/actionBarSize"

This will account for changes in size based on screen configuration automatically. You can see a demo of its use in the "Overlay" example of the 'Demos' sample that comes with ActionBarSherlock.
