Android :: Android - Layout - How To Create A Header-content Layout

How do I go about creating the following layout in Android?

I want a "header", that is, a header that stays the same at all times. The only thing that should change is the area below the header.

Think of it as a webpage, where the content-area is where its all happening =)

Sure, its easy enough to create a LinearLayot, add a View on the top and then another view below that - tada! But what Im after is how you "set up" or design the project so its easy to just change whats in the Content.

What I really would like is to be able to "swipe" (see here) the area and then just "roll in" a new View/thing in the Content-area, but keep the same header.
