如果ACTION_UP取消动画

Question

I have onTouchListener on my gridView and if ACTION_DOWN is pressed the animation(scale) starts. How do following things:

1. How to hold scaled image if it's ACTION_DOWN pressed
2. If is ACTION_DOWN animation is started but then if ACTION_UP (if animation is not complete) animation is instantly gone (back to time before animation start)

Answer 1

In order to get the Animation's final state to stick after it is complete, you need to call Animation.setFillAfter(true)

You can reset a running animation at any time with Animation.cancel() and Animation.reset() to put the view transformation back to its initial state.
