我想在地图片段和其他片段中显示当前位置和特定的附近地点（例如医院）

Question

我在导航抽屉里面制作了地图片段，它的工作非常精细，但它没有显示当前位置。另外我想在导航抽屉按钮点击事件上显示附近的地方。 我的应用程序设计看起来像http://prntscr.com/jta0i5

地图片段代码

import static com.google.android.gms.maps.model.BitmapDescriptorFactory.*;

public class GmapFragment extends Fragment implements OnMapReadyCallback {

    private GoogleMap mMap;
    private static final int Location_Request = 500;


    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_gmaps, container, false);
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        MapFragment fragment = (MapFragment) getChildFragmentManager().findFragmentById(R.id.map);
        fragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {

        mMap = googleMap;
        mMap.getUiSettings().setZoomControlsEnabled(true);



         LatLng pindora = new LatLng(33.6498,73.0686);
        googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(pindora, 13));

        googleMap.addMarker(new MarkerOptions().title("Hello Google Maps!").position(pindora));



    }



}
