I don't believe I am. Initially I did not realize that the Gallery only has visible items as children. I understand that now. AFAICT, this was not documented anywhere... Hence the confusion. > > If I have 20 items, and scroll to the 16th... then that means items 14 - 18 > > are visible.

I just didn't describe it as well as you did. I believe that since the gallery deals with displaying views and the pointToPosition() method deals with a point on the screen that it should return the index of the view at that point, rather than the index of the data array. I think it would be better to have that functionality on the adapter, rather than the gallery. Thank you for your help. It has helped me understand how things work and I now know how to proceed to get the results I want.
