Forgot to mention, the progress indicator is indeterminate, like you
have in an Activity with Window.FEATURE_INDETERMINATE_PROGRESS.

I've had a look at RotateDrawable, which seems to be the correct thing
for me to use. The docs say a RotateDrawable should be used with an
xml that uses <rotate>. I've tried various methods to get it to
animate:

img.setImageDrawable(getResources().getDrawable(R.drawable.progress))
img.setImageDrawable((RotateDrawable) getResources().getDrawable
(R.drawable.progress))
and img.setImageDrawable(R.drawable.progress)

All of these bring up a static image. Just to clarify, I think it
might have been unclear earlier, my ListView row looks like this: |
[Text           ][Image]| where | is a boundary of a view container.
The image box can contain various images to indicate the state of
background activity, a red circle to indicate something wrong, green
to show nothing unexpected has happened, etc. The indeterminate
progress (should) show up when the user requests an operation that
will (possible) take a while to complete.
