Android Fragment Layout Help

Question

I am interested in the way that gmail handles fragments and their transitions. I'm trying to do something somewhat similar and am running into an issue. Could someone give me a high level over view of how to accomplish this?

1. start with ActivityA that has fragmentA that takes up the entire screen
2. when a user clicks on an element in fragmentA I would like to have fragmentB and fragmentC replace A and fragmentC to expand to fill most of the window (basically a weight of 1)

This seems like a simple thing, but I'm running into some problems. I don't need any advice on how to do the clicks or other things, but I would like some advice in how to lay it out correctly. Do I only use one activity? Am I hiding fragmentA and then adding fragmentB and fragmentC? Do I use a ViewSwitcher for the two cases and then just do a slide animation?

Thanks!

Romain Guy's Honeycomb PhotoAlbum app uses a technique to shift views along. I haven't had a chance to look at the code yet, but you might get some inspiration there?

Look for SwipeyTabs (I know this is an old post but in case someone comes across it).
