How to get reference to a view of a fragment that's in a ViewPager?

I have a Fragment in a ViewPager, and I want to access a View in said Fragment in order to change its background from the FragmentActivity.

I've been trying with every answer related I could find. No luck yet. Any ideas?

Solution

  • Try this to get your fragment : 

    YourFrag frag = (YourFrag) viewPager.getAdapter().instantiateItem(viewPager, pageNumber);

    then you can get the views as usual

    frag.getView().findViewById() ...

    or however you like.
