I'd like to implement a small feature on my application that allows the user to swipe left and swipe right on a fixed part of the screen. A swipe left would call a certain method and a swipe right would call a different method. I've seen swipe examples where the activity changes upon swiping left or right, but I only want to call methods, and have it only available on a small part of the screen.
Is this possible? Can anyone point me in the right direction to a library or good tutorial?
