Fling gesture detection on grid layout

Question

I want to get fling gesture detection working in my Android application.

What I have is a GridLayout that contains 9 ImageView

Answer 1

There is a lot of excellent information here. Unfortunately a lot of this fling-processing code is scattered around on various sites in various states of completion, even though one would think this is essential to many applications.

I've taken the time to create a fling listener that verifies that the appropriate conditions are met. I've added a page fling listener that adds more checks to ensure that flings meet the threshold for page flings. Both of these listeners allow you to easily restrict flings to the horizontal or vertical axis. You can see how it's used in a view for sliding images. I acknowledge that the people here have done most of the research---I've just put it together into a usable library.

These last few days represent my first stab at coding on Android; expect much more to come.
