Buttons scrolling the gallery

Question

In my application I have a Gallery view and two buttons to scroll it - left and right. Scrolling the gallery by fling also works, and here is the problem: how can I update the states of buttons after the user scrolled the Gallery using fling movements? Is there any callback that tells that Gallery's selected item has changed? Thanks.

There is an onItemSelectedListener that you can use with a gallery. If you use it you'll probably also want to read about setCallbackDuringFling() that can enable/disable the listener while flinging.
