So, I am creating an App, where I am adding multiple Geo-Fencing. But, as my current location is moving but the map is not moving, so the current location is going outside the map view. To summarize, the current location dot is not in the center of the map while it's moving. So, what changes I need to make. Kindly, reply.
Here is my Hotspot.class (Java)
package com.example.testaid;
public class Hotspot extends AppCompatActivity implements OnMapReadyCallback, GeoQueryEventListener {
private GoogleMap mMap;
private FusedLocationProviderClient mFusedLocationProviderClient;
private PlacesClient placesClient;
private List<AutocompletePrediction> predictionList;
private DatabaseReference myLocationRef;
private GeoFire geoFire;
private List<LatLng> dangerousArea;
private Location mLastKnownLocation;
private LocationCallback locationCallback;
private MaterialSearchBar materialSearchBar;
private View mapView;
private final float DEFAULT_ZOOM = 18;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hotspot);
Window w = getWindow();
w.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//Maps
materialSearchBar = findViewById(R.id.searchBar);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
settingGeoFire();
initArea();
mapView = mapFragment.getView();
mFusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(Hotspot.this);
Places.initialize(Hotspot.this, "Your API key");
placesClient = Places.createClient(this);
AutocompleteSessionToken token = AutocompleteSessionToken.newInstance();
//Bottom Navigation Bar
BottomNavigationView bottomNavigationView = findViewById(R.id.bottom_nav);
bottomNavigationView.setSelectedItemId(R.id.hotspot);
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.home:
