活动地图绑定不工作，它不让我导入类-无法解决符号'活动地图绑定'

Question

我正在尝试让谷歌地图在我的应用程序中工作，当我通过android studio关闭谷歌地图时，它会以红色的ActivityMaps绑定显示，然后它就不能正常工作了？我已经把成瘾和类似的东西，但它不起作用

public class TrovamicoActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap;
private ActivityMapsBinding binding;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    binding = ActivityMapsBinding.inflate(getLayoutInflater());
    setContentView(binding.getRoot());

    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(-34, 151);
    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
