Desk clock scrollable tab bar - what's it called?

I'd like to find some examples, of how to implement a scrollable tab bar as found in the htc's desk clock app as seen below

Not sure what I should be looking for though开发者_Python百科? What's it called?

Listview is not an option, as it does not support horizontal scrolling. I would make it based on a HorizontalScrollView. See the manual
