回答1:

MapView has a tapped event, as well as multiple Touches* events

mapView.Tapped += delegate(object sender, GMSCoordEventArgs e) {
  Console.WriteLine("tapped at " + e.Coordinate.Latitude + "," + e.Coordinate.Longitude);
};

GoogleMap : Marker click event with and without ClusterManager

For Xamarin.iOS , Google Map will use TappedMarker event. It might be used in three different ways.

First way of implementation:

You can directly use MapView Delegate event didTapMarker . It will work along with GMUClusterManager such as

    [Export("mapView:didTapMarker:")]
    public bool TappedMarker(MapView mapView, Marker marker)
    {
        var id = marker.Title;
        Console.WriteLine(id);

        return true;
    }

Second way of implementation:

For your GoogleMap, we can directly use TappedMarker method

    this.GMapView.TappedMarker = (map, marker) =>
    {
        var id = marker.Title;
        Console.WriteLine(id);

        return true;
    }

Third way of implementation:

For your GoogleMap , you can use your own custom method for TappedMarker event.

    this.GMapView.TappedMarker = markerClicked;

Definition of markerClicked is here

    bool markerClicked(MapView map, Marker marker)
    {
        var id = marker.Title;
        Console.WriteLine(id);

        return true;
    }
