Map show current location

I used the code below:

private GoogleMap.OnMyLocationChangeListener myLocationChangeListener = new GoogleMap.OnMyLocationChangeListener() {
    @Override
    public void onMyLocationChange(Location location) {
        LatLng loc = new LatLng(location.getLatitude(), location.getLongitude());
        mMarker = mMap.addMarker(new MarkerOptions().position(loc));
        if(mMap != null){
            mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 16.0f));
        }
    }
};

Then set on your map:

mMap.setOnMyLocationChangeListener(myLocationChangeListener);

Dude, try this here:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.the_map)).getMap();

    mMap.setMyLocationEnabled(true);

    myPosition = getMyLocation();

    markerClicked = true;
    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(myPosition, 18));

}

private LatLng pegaMyLocation(){
    try{
        // Getting LocationManager object from System Service LOCATION_SERVICE
        LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

        // Creating a criteria object to retrieve provider
        Criteria criteria = new Criteria();

        // Getting the name of the best provider
        String provider = locationManager.getBestProvider(criteria, true);
        // Getting Current Location
        Location location = locationManager.getLastKnownLocation(provider);

        if(location!=null){
            // Getting latitude of the current location
            double latitude = location.getLatitude();

            // Getting longitude of the current location
            double longitude = location.getLongitude();

            LatLng my = new LatLng(latitude, longitude);

            return my;
        }
    }catch(Exception e){
        Log.e("Erro", "(pegaMyLocation) : "+e);
    }


    return null;
}

This is how I do it

private FusedLocationProviderClient mFusedLocationProvider;
MapView mMapView;
GoogleMap googleMap;

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

    mMapView = (MapView) rootView.findViewById(R.id.mapView);
    mMapView.onCreate(savedInstanceState);

    mMapView.onResume(); // needed to get the map to display immediately

    mFusedLocationProvider = LocationServices.getFusedLocationProviderClient(getActivity());

    try {
        MapsInitializer.initialize(getActivity().getApplicationContext());
    } catch (Exception e) {
        e.printStackTrace();
    }

    mMapView.getMapAsync(new OnMapReadyCallback() {
        @Override
        public void onMapReady(GoogleMap mMap) {
            googleMap = mMap;

            googleMap.setBuildingsEnabled(false);
            if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
                return;
            } else {
                googleMap.setMyLocationEnabled(true);

                mFusedLocationProvider.getLastLocation()
                        .addOnSuccessListener(getActivity(), new OnSuccessListener<Location>() {
                            @Override
                            public void onSuccess(Location location) {
                                // Got last known location. In some rare situations this can be null.
                                if (location != null) {
                                    googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 13));

                                    CameraPosition cameraPosition = new CameraPosition.Builder()
                                            .target(new LatLng(location.getLatitude(), location.getLongitude()))      // Sets the center of the map to location user
                                            .zoom(14)                   // Sets the zoom
                                            .build();                   // Creates a CameraPosition from the builder
                                    googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

                                }
                            }
                        });

            }

        }
    });

    return rootView;
}

This code also shows how I map the map, if necessary
