Как вызвать onMapReady () из onResume

Question

Как вызвать onMapReady () из onResume

1

Я хочу вызвать метод onMapReady из onResume. Проблема в том, что он имеет

(Карта GoogleMap)

и я не могу просто так это назвать

onMapReady();

Вот метод

@Override
public void onMapReady(GoogleMap map) {
    GMap = map;
    GMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(49.8117806, 15.6970293), 6.0f));
    if (!getloc)
        getLocation();
}

ОБНОВЛЕНИЕ Вот весь класс

public class Map extends AppCompatActivity implements LocationListener, OnMapReadyCallback, NavigationView.OnNavigationItemSelectedListener {


@Override

        }
    });

}
}

Я сделал это, положив

getloc = ложь

поэтому методы getlocation() вызываются каждый раз!

@Override
public void onMapReady(GoogleMap map) {
    GMap = map;
    GMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(49.8117806, 15.6970293), 6.0f));
    getloc=false; //THE NEW ADD
    if (!getloc)
    getLocation();
}
