Populate a Listview from another Fragment
===

I'm trying to make a tabbed android app. Both tabs are listviews. The first tab gets posts from an RSS Feed. The second tab displays them organized into categories.

The problem is that I want to populate the listview in the second tab from the fragment of the first tab. 

My code for the first fragment is:

    public class PostsFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.posts_fragment, container, false);
		return view;
    }
    
    ...
    ...
    ...
    
    // Populate the "posts_fragment.xml" with Posts 
    public void populate_postview() {
    	ListView lv1;
    	
        lv1 = (ListView)getView().findViewById(R.id.postlist);
    	lv1.setAdapter(new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1 , arrays.PsychoTitle));
        lv1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
		    public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
		    	...		    	
		    }
		});

    // Populate the "categories_fragment.xml" with Categories
    public void populate_catview() {
    	ListView lv2;

    	lv2 = (ListView)getView().findViewById(R.id.catList);
    	lv2.setAdapter(new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1 , arrays.PsychoCategories));
    }


The problem here is that `catList` in `populate_catview()` is a part of "categories_fragment.xml" but using `getView()` returns the current layout which is "posts_fragment.xml".

So how can I populate the item list in the second fragment?
