Want to use GoogleMaps - OnMyLocationChangeListener but can't implement it? Any other options

I want to utilize Google Maps, OnlocationChangeListener but because I've already implemented

implements DatePickerFragment.OnDATEClickListener{

And as the above needs to remain implemented, this is making implementing OnlocationChangeListener very difficult. Also the  onLocationchangelistener code currently extends fragmentActivity whereas my current codeextends  fragment which creates further problems.

The problem is: I can't extend or implement anything else as I'm already implementing and extending. Which means I can't get OnlocationChangeListener to work

Do you know of any work around?

(To allow me to implement DatePickerFragment.OnDATEClickListener whilst also implementing Google's OnlocationChangeListener. Whilst also having my code continue to extend fragment rather than fragmentactivity)

My Current Code:

    public class HomeFragment extends Fragment implements DatePickerFragment.OnDATEClickListener{
         
        public HomeFragment(){}
         
        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
      
            View rootView = inflater.inflate(R.layout.fragment_home, container, false);
              
            return rootView;
        }
    }

Google Maps Location Change Listener Code:

                    Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
