Fragment loading spinner/dialog in Honeycomb

Question

When loading data into my Fragments I would would like to have an indeterminate spinner in the middle of the fragment (example in pic below) to show the user that content is loading within that particular pane.

What's the best way to do this in Honeycomb?

I don't really want to use a spinner in the action bar, it's not immediately obvious where data is loading. Also, I don't want an indeterminate progress dialog because it appears in the center of the entire app and also stops the user from doing anything else until it is dismissed. N.B. FragmentDialogs seem to do this also.

Am I going to have to hack around with a custom FrameLayout to get the desired effect for each pane?

Answer 1

If you're using a ListFragment you can call setListShown(false) to display a loading progress indicator until you call setListShown(true). You can call these in the fragment's Loader callback methods to show the indicator while the list is loading.

Answer 2

I think the best way to accomplish this would be to use a ViewSwitcher. Then if you are using a loader, you can just switch between the views (the loading view and the content view) after the load has been completed.
