Catching then Fragment got changed in FragmentStatePagerAdapter

I'm trying to catch a moment then user has switched to the next Fragemnt in FragmentStatePagerAdapter. I have tried to override onPause() function inside my Fragment, but it does not called, until user has switched two pages (probably, because of animation).

I also have tried to override the onResume() function, and have found out, that it is called for two fragments at the same time.

Is there a function what should indicate witch fragment being switched on?

I'm thinking now to override FragmentStatePagerAdapter getItem and keep the list of created items, so I can at least refer to Fragment from a separate function, but is there is a better way?

Thanks

IMHO, that is not the job of FragmentStatePagerAdapter, but rather of whatever activity or fragment hosts your ViewPager.

Call setOnPageChangedListener() on your ViewPager to register an OnPageChangedListener, to find out when the user changes pages.
