How to create 2 Fragment inside Fragment of each Nav Tab

Question

I follow Action bar tutorial in Android Dev site

In onCreate of ActionBarActivity.class I add tab like this;

    Tab tab = actionBar.newTab()
            .setText(R.string.artist)
            .setTabListener(new TabListener<ArtistFragment>(
                    this, "artist", ArtistFragment.class));
    actionBar.addTab(tab);

so, I will have ArtistFragment extend Fragment but I'm not sure how to add 2 fragment(ListFragment and DetailFragment) inside ArtistFragment What would be inside ArtistFragment.class?

Answer 1

What Warpzit said. Per Android: Can you nest Fragments?, Fragments cannot be nested. Your Fragment can cause another Fragment to be instantiated alongside it by reaching up to its parent Activity. I wouldn't ordinarily recommend this, as Fragments should be a unit of encapsulation. But if your Fragments are tightly coupled (for example, a detail display corresponding to a list item), I could see doing it.

Your code would look something like this:

            FragmentManager fm = getActivity().getSupportFragmentManager();
            MyFragmentClass myFragment = new MyFragmentClass();
            fm.beginTransaction().add(android.R.id.content, myFragment).commit();

Android doesn't support fragment in fragments (for now). You should try to make a layout that supports 2 fragments that communicate with your activity instead OR 1 fragment which handles the work that both fragments would do.

I've found the FragmentTabs example from the API Demos project to be very useful.

Just create a new Android sample project from Eclipse and choose the API demos (try API 13). Also for the support (compatibility) library, there's a FragmentTabs demo in the Support4Demos
