Android action bar slide-out animation with RecyclerView -

-

i want achieve following effect:

i have recyclerview 

android:fitssystemwindows="true" android:cliptopadding="true"

and while scrolling, actionbar should hide sliding out of screen when "hit" element of recyclerview. if being pushed out of screen recyclerview element. (so actionbar.hide() won't do). if scroll stops actionbar having been pushed halfway out, should hide completely. actionbar should reappear when scrolling down again.

all in same effect of action bar in newsstand app.
