android - How to keep actionbar fixed across all activities? -


in facebook app v2.3, when navigate 1 activity(or frgament?) another, actionbar stays fixed across activities(or fragments?). example, if navigate news feed someone's profile page, action bar stays constant, , page below refreshed. question is, possible have behavior using activities? or should have 1 main activity, , fragments sub activities?

one activity , many fragments need.

the moment call startactivity(intent); framework roll activity transition animation contents (including action bar)
