Find out if ActionBar is stacked

Question

If you add tabs to your ActionBar, they will be in an extra stacked ActionBar on phones in portrait mode. Is there an easy way to find out whether

Answer 1

This behavior is called Split Action Bar. It happens when the AndroidManifest is set with uiOptions="splitActionBarWhenNarrow" in the or element.

Android adjusts the action bar's appearance in a variety of ways, based on the current screen size. Using split action bar is just one option that you can enable to allow the action bar to further optimize the user experience for different screen sizes. In doing so, you may also allow the action bar to collapse navigation tabs into the main action bar. That is, if you use navigation tabs in your action bar, once the action items are separated on a narrow screen, the navigation tabs may be able to fit into the main action bar rather than be separated into the "stacked action bar".
