[android-developers] Listview notification?

I have a listview which has an ImageView in each item and a couple of buttons.  The buttons allow the user to rotate the image clockwise and counter clockwise by 90 degrees on each press.  This works find and the ImageView is rotated, however if I scroll the item off view, when I scroll it back into view the orginal image is restored without any rotation applied, is there a notification that I can get when the item comes into view so I can correct the image or....can I modifiy the original ImageView in the list view directly?
