Maps API v2 with different marker actions

Question

I\'m trying to port my application to the new Google Maps API v2, but i\'m having trouble when interacting with markers.

My context: I have a map showing buses and

Answer 1

I have run into this problem as well. My solution was:

private Map markerMap = new HashMap<>();
private GoogleMap mMap;

private void doMarkers(){
    MarkerOptions opt = new MarkerOptions();
    //Fill out opt from MyModel
    Marker marker = mMap.addMarker(opt);
    markerMap.put(marker, myModel);
}

and then in the OnMarkerClickListener callback, pull your model out of the HashMap using the clicked marker. There is also a method Marker.getId() which for some reason returns a string. I don't understand why you can't specify an int id when you make the marker, or why you can't access the marker object before you add it to the map.

UPDATE: After almost 4 years Google have added a method Marker.setTag(Object tag) to associate arbitrary data with a marker.
