By overwriting getItemPosition() method I can refresh my FragmentStatePagerAdapter, which works fine. But the change of the contents is not nice to see.
Is there possibility to apply any kind of animation as I refresh the FragmentStatePagerAdapter?
I was also facing same issue.So, what should you do. Make global variables in your adapter for what you want continuous animate.
Now when you start animation on button click. Pass value to global variables.
When you notifydatasetchanged it doesn't effect your animation.
I haven't found any correct way. So, did this thing.It's working perfect.
