Calling this results in null if the fragment has a parent which is an Activity. Have a look at this. If you are using support library then you can use getParent(), may be you … Read more

I found the problem. It took me two days, but hey, it’s fixed. Instead of using mAdapter = new AlbumAdapter(getFragmentManager(), mActiveProject.getInspiration()); You should use mAdapter = new AlbumAdapter(getChildFragmentManager(), mActiveProject.getInspiration()); So much for 5 characters.

The asyncTask is to make the original fragment complete it’s transition. and then we proceed with viewPager fragments, basically to avoid recursion. @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { mView = inflater.inflate(R.layout.team_card_master, container, false); mViewPager = (ViewPager)mView.findViewById(R.id.team_card_master_view_pager); final Button button … Read more
Assuming you have created the correct xml layouts. It is now very simple to display fragments in a ViewPager that is hosted by another Fragment. The following is a parent fragment that displays child fragments: class ParentViewPagerFragment : Fragment() { override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? { val root = inflater.inflate(R.layout.fragment_parent_viewpager, container, … Read more
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
The best way is use an interface: Declare an interface in the nest fragment // Container Activity or Fragment must implement this interface public interface OnPlayerSelectionSetListener { public void onPlayerSelectionSet(List<Player> players_ist); } Attach the interface to parent fragment // In the child fragment. public void onAttachToParentFragment(Fragment fragment) { try { mOnPlayerSelectionSetListener = (OnPlayerSelectionSetListener)fragment; } catch … Read more
I solved this problem with the following code (support library is used): In container fragment override onActivityResult in this way: @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); List<Fragment> fragments = getChildFragmentManager().getFragments(); if (fragments != null) { for (Fragment fragment : fragments) { fragment.onActivityResult(requestCode, resultCode, data); } } } Now … Read more
