java - 制造商在谷歌地图上调用相同的 Activity

Question

我在应用 Google map 上的创客来调用 Activity 时遇到了一些问题。我可以成功创建点，甚至可以通过单击它们来调用 Activity ，但问题是，无论我做什么，它们总是调用相同的 Activity 。有人可以帮助我吗？

已经尝试移动变量，已经尝试移动 celula01 变量以查看是否建立连接，但这些都没有给出任何返回。

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap, mCel;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // 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;
    mCel = googleMap;

    LatLng celula04 = new LatLng(-23.174601, -45.839513);
    mCel.addMarker(new MarkerOptions().position(celula04).title("Célula da Maria"));
    mCel.moveCamera(CameraUpdateFactory.newLatLng(celula04));
    mCel.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener(){
        @Override
        public boolean onMarkerClick(Marker marker) {
            Intent intent = new Intent(MapsActivity.this, Celula02.class);
            startActivity(intent);
            return false;
        }
    });

    LatLng celula01 = new LatLng(-23.173300, -45.821273);
    mMap.addMarker(new MarkerOptions().position(celula01).title("Célula do Rafael"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(celula01));
    mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener(){
        @Override
        public boolean onMarkerClick(Marker marker) {
            Intent intent = new Intent(MapsActivity.this, Celula01.class);
            startActivity(intent);
            return false;
        }
    });

    }
}

谢谢。
