My setAnimationListener on my viewFlipper keeps running the overlay before
the animation is complete. Here is my fragment, I think I am just not
calling my listener correctly but not entirely sure if it will work since i
have multiple animations running.
Basically I have a viewFlipper that acts as a random category selector when
you swipe, once it stops on a category I then open an overlay with some
info then wait 3 seconds and load a new fragment but things are just not
working right. If you have any other ideas I can try I would appreciate the
help! Thanks!
