Android Question Creating drop down in photo gallery

[Bpick]

I am working on a graphics filter app that allows the user to flip, rotate, and alter the appearance of the photo (b/w, sepia).

I'd like to make it very easy to do so by adding a drop down option in the photo gallery.

How would I create such a drop down? Or would I need to do a file pick and then add it there?

Thanks!

Have you considered a spinner, Would that work? just a thought.

See this links for example code.

I have thought of a spinner, however, I'm having a devil of time actually PICKING the image.

I might be able to use ListViewDirContent, but it is bulky. I like Scrollview, but I can't pick the image I click on.
