OnInfoWindowClickListener 实现

Question

我一直在尝试使用 OnInfoWindowClickListener，因此当用户点击我的标记的信息窗口时，它会将他们带到我命名为 PageActivity 的另一个活动。但是，我在网上找到的所有实现似乎都不起作用，而且谷歌地图 api 文档中提供的布局似乎也不起作用。 此外，线 mMap.setOnInfoWindowClickListener(new OnInfoWindowClickListener() { 在代码的底部，出现红色，尤其是 new OnInfoWindowClickListener()

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap;

@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;
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
        mMap.setMyLocationEnabled(true);
    }
    // Add a marker in Sydney and move the camera

    //mMap.addMarker(new MarkerOptions().position(new LatLng(0,0)).title("Lets try this").snippet("gotcha"));
    //LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    //Location myLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    //mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    //double user_latitude = myLocation.getLatitude();
    //double user_longitude = myLocation.getLongitude();
    //LatLng user_coord = new LatLng(user_latitude, user_longitude);

    //mMap.animateCamera(CameraUpdateFactory.zoomTo(14));
    //mMap.addMarker(new MarkerOptions().position(new LatLng(user_latitude,user_longitude)).title("You are here"));
    LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    String provider = locationManager.getBestProvider(criteria, true);
    Location location = locationManager.getLastKnownLocation(provider);

    if (location != null) {

        LatLng target = new LatLng(location.getLatitude(), location.getLongitude());
        CameraPosition position = this.mMap.getCameraPosition();

        CameraPosition.Builder builder = new CameraPosition.Builder();
        builder.zoom(15);
        builder.target(target);

        this.mMap.animateCamera(CameraUpdateFactory.newCameraPosition(builder.build()));
        //Marker our_marker = mMap.addMarker(new MarkerOptions().position(new LatLng(location.getLatitude(), location.getLongitude())).title("Local Bathroom").snippet("Tap for Rating").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));

                startActivity(intent);
            } });

如果您的代码与发布的代码完全相同，则您有一个额外的括号，这就是mMap.setOnInfoWindowClickListener 是红色的原因

尝试在mMap.setOnInfoWindowClickListener 行之前删除{，监听器应该可以工作
