Determine if action bar is split

Question

I have a MapView with an action bar powered by ActionBarSherlock. The action bar is both split (on \"narrow\" screens) and overlayed / semi-transparent (android

Answer 1

I ran into the same problem. On phone devices in portrait mode the actionbar is split. So menu-items are in the top actionbar and the tabs in a second actionbar (tabbar) below. I just did not find any possible way to determine the height of the actionbar: to see what space is left on the screen before building my screen.

So I did an assumption:

• on small and normal screensize devices the actionbar is split in portrait mode
• on large screensize devices (like Nexus 7) the actionbar is also split in portrait mode
• on xlarge screensize devices (tablets) the actionbar is not split in portrait mode

So I distinguish the different screensizes and created a bool resource

    false





    true

In the code I access the value like this:

Boolean isSplit = getResources().getBoolean(R.bool.is_split_actionbar);

To get the actionbar height in the onCreateView() method:

TypedValue typedVal = new TypedValue();
getActivity().getTheme().resolveAttribute(R.attr.actionBarSize, typedVal, true); // use android.R when not using ABS
int actionBarHeight = getResources().getDimensionPixelSize(typedVal.resourceId);

And double the height if the actionbar is split:

if(isSplit) 
    actionBarHeight = actionBarHeight * 2;

It is not an ideal solution, but for me this works.
