I'm currently using ActionbarSherlock example with tabs and fragments (FragmentTabs, without viewpager).

And on pre 4.0 devices is not so good:
How to make tabs on pre android 4 looks the same as on android 4+? Maybe someone have already did it and could share the solution?
I had tried to use Android Action Bar Style Generator, but the style didn't effect on this tabs. They looked the same.
Here is the Fragment tabs layout and here is FragmentTabs.
