Answer 1

I suppose you can use scale animations on ImageViews that simulate the paper already folded. The scale effect would be used when you scroll through and expand the entire paper as you continue to scroll through the sets of images. Once you fully scroll through the paper ImageView and the animation is completed, you just kill the animation and have a normal view of a full page paper. Just make a separate folder for animation and inside that folder, create an XML file, select scale and play around with the attributes to test the best suitable effects for your animation.

Hope this helps!

There is a library that helps to implement not accordion-like but another quite interesting folding effect: http://www.youtube.com/watch?v=GzWGhp_NDTg
