How to set a ViewPager inside a Fragment

Question

I need to place a ViewPager inside of a fragment, but I have two fragments, Fragment 1 is my MENU, and Fragment 2 I want to use as a ViewPagerIndicator.

But a fragment can't have another fragment... what do I need to do for that?

Answer 1

Starting in Android 4.2, there are nested fragments.http://developer.android.com/about/versions/android-4.2.html#NestedFragments The support library now also includes support for this for older Android versions.

So you can do something like this:

@Override     public void onViewCreated(View view, Bundle savedInstanceState) {     super.onViewCreated(view, savedInstanceState);      ViewPager mViewPager = (ViewPager) view.findViewById(R.id.viewPager);     mViewPager.setAdapter(new MyAdapter(getChildFragmentManager()));     } 

Full implementation available here: https://github.com/marcoRS/nested-fragments/tree/master/src/com/burnside/digital/nestedfragments

Answer 2

You must use getChildFragmentManager() instead of getSupportFragmentManager() to get the FragmentManger inside a Fragment. But you should not use FragmentStatePagerAdapter rather than FragmentPagerAdapter.
