I’m an android newbie so forgive me if this is a noobish question.
I’m trying to have some menu which is located on top of the screen and I want it to be in every single activity inside my application.
Now my question is how can achieve this goal? Should I create an XML an include it every where or should I have a base activity and host my other activities inside that?
UPDATE: Look at the screenshot below, I want exactly the same. If you notice you see 2 sets of buttons one on top and the other on the bottom. The middle screen is scrollable.

I usually create the bottom and top toolbars as separate layout xml files and inclue them in the activities I need them. I also create a base activity which can handle both toolbars. You can put the top toolbar to actionbar programmatically, if it’s available.
