I have a tabbed action bar on a narrow screen that renders as shown in the right-hand image below:

I’d like to also squeeze an “always show” menu item to the main action bar. However, when I introduce the menu item to the layout, a second action bar containing just the menu item is created directly below the tabbed bar.
Of course, I’ve disabled the action bar icon and title (with setDisplayShowHomeEnabled(false) and setDisplayShowTitleEnabled(false)) to get the single-line action bar before adding the menu item.
Is it possible using the standard action bar to accomplish this?
