<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

JAVA

public class UserDetails extends ListFragment  {
    ArrayAdapter<String> adapter;
    ArrayList<String> userIndex = new ArrayList<String>();
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View android = inflater.inflate(R.layout.users_tab, container, false);   
        adapter = new ArrayAdapter<String>(inflater.getContext(),R.layout.single_user_chat_tab,userIndex);
        setListAdapter(adapter);
        return android;
    }
}

I don't think you can call setListAdapter before returning your custom View in the onCreateView. I see 3 solutions

Either call super.onCreateView() instead of inflating
Either set your adapter in OnActivityCreated
Either write android.findViewById(android.R.id.list).setAdapter(adapter); instead

even if i removed the adapter still shows same exception. – Android Learner Feb 13 '14 at 12:04
So the easy way to go around the problem: Just implement simple Fragment, the list fragment does not bring real convenience. – Benoit Feb 13 '14 at 13:11

When using ListActivity or ListFragment, we must have a ListView in our layout xml whose id is = @id/android:list. Since ListActivity and ListFragment internally use this id to create a list and this is the list which is referred or returned by getListView(). – Atul O Holic Feb 13 '14 at 10:48

content must have a ListView whose id attribute is 'android.R.id.list'
