Android title buttons

I am trying to reproduce the account chooser widget that the GMail app has on top right.

I know already how to put things in the title but i have several problems:

• I've tried putting a normal button in the title but it doesn't fit
• It looks like the size of the title is bigger than what it is, for example if I put a normal button there, there is no way of making it the proper height, in fact goes below the app开发者_开发百科 like if half of the title space was hidden below
• I thought it might be a clickable label with a rectangular shape, but I tried it and no way to make it work.

Any hint?

Looking at the layout using the hierarchy viewer it seems like it really is just a Button inside a LinearLayout. The only interesting part is that the LinearLayout's layout_height is set to MATCH_PARENT (which is just the newer version of FILL_PARENT) where its parent the RelativeLayout has a hardcoded layout_height of 54.

I'm not sure if this is of help for you but maybe it can point you in the right direction.
