android - Horizontal "tab"ish scroll between views

Question

I'm interested in creating a horizontal scroll view that "snaps" to the viewed item, so only one item is ever shown at a time. The user can touch-drag left/right and will see previous/next views, switching to it if there's enough velocity. This interaction is exactly like what the new weather/news widget that comes with the Nexus One does for navigating between its "tabs".

Are there any existing view widgets that do this?

Update: found a copy of the news/weather widget (GenieWidget) and they seem to have implemented their own widget to accomplish this which they call com.google.android.apps.genie.geniewidget.ui.FlingableLinearLayout which is part of their own custom com.google.android.apps.genie.geniewidget.ui.TabView. As that source isn't available, that's not looking too hopeful a direction.

(update 20110905: Official android tools now do this better)

I cloned Eric Taix's http://code.google.com/p/andro-views/ on github

https://github.com/olibye/AndroViews

Then applied the patches from above:

• JonO's patch

• Tom de Waard's patch

• Split into a library and an example, allowing simple inclusion in other projects

I would have made this comment above, however I didn't appear able to comment on JonO's answer
