Update data in ListFragment as part of ViewPager

Question

I\'m using the v4 compatibility ViewPager in Android. My FragmentActivity has a bunch of data which is to be displayed in different ways on different pages in my ViewPager.

Answer 1

Also works without problems:

somewhere in page fragment's layout:

in fragment's onCreateView():

...
View root = inflater.inflate(R.layout.fragment_page, container, false);
ViewGroup ref = (ViewGroup)root.findViewById(R.id.fragment_reference);
ref.setTag(this);
ref.getChildAt(0).setTag("fragment:" + pageIndex);
return root;

and method to return Fragment from ViewPager, if exists:

public Fragment getFragment(int pageIndex) {        
        View w = mViewPager.findViewWithTag("fragment:" + pageIndex);
        if (w == null) return null;
        View r = (View) w.getParent();
        return (Fragment) r.getTag();
}
