android - Fragment returning Null context

Question

I've been trying to fix this for the past 2 hours. Tried a lot of things.

The Fragment seems to be passing a null context to my Adapter. I have tried to initialize the Context variable in onCreate and onCreateView and onActivityCreated. Same result.

Here is my fragment:

    public class ActiveBookingsFragment extends Fragment
{
    Context con;
    ArrayList<Booking> bookings;
    ListView activeBookings_lv;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState)
    {
        super.onActivityCreated(savedInstanceState);

        con = this.getActivity();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState)
    {
        View v =inflater.inflate(R.layout.tab_activebookings,container,false);

        activeBookings_lv = (ListView) v.findViewById(R.id.lv_activebookings);
        bookings = new ArrayList<Booking>();

        Booking b1 = new Booking("Data");
        bookings.add(b1);

        activeBookings_lv.setAdapter(new BookingAdapter(con, bookings));

        return v;
    }
}

And here is the logcat error:

Answer 1

Initialize context in Fragment onAttach(.....) like

 @Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    con = getActivity();
    }
}
