Android: Sliding button container widget

I am running out of room on my app for buttons, so I want to stick them into some sort of sliding container, like the one at the top of the Astro File Manager app. How do I go about doing this? I've Googled this and can't find开发者_JS百科 anything.

put your buttons in a scrollview, that is exactly how its done in the contacts popup in 2.x devices.
