问题
I'd like to animate the transition between two fragments which is performed thanks to FragmentTransaction.replace(). I'd like to specify my custom animation in a XML file.
What is the difference between calling FragmentTransaction.setCustomAnimations() and FragmentTransaction.setTransitionStyle() ?
Thanks.
回答1:
setCustomAnimations(int, int, int, int) allows you to specify your animation resources directly. If you use setTransitionStyle(int), on the other hand, you'll have to specify them by using a FragmentAnimation style and setTransition(int).
It is worth mentioning that the compatibility library ignores setTransitionStyle(int), so if you are using it you have to use setCustomAnimations(int, int, int, int) for sure.
