Make these 'double' not 'Float'. The former are primitive types, the
latter are objects.

Add 'final' in front of the parameter named 'newmarker' in your
method. I hope that's enough to get you started.

multiple markers from database
Hi there
It's about maps and markers.
So I have a table with some location (restaurants) and their coordinates.
I'm adding marker to the map like this:
MarkerOptions mo = MarkerOptions.newInstance();
mo.setClickable(true);
mo.setTitle(result[j][1] + ", " +
result[j][0]);
Float lt = new
Float(result[j][2].toString());
Float ln = new
Float(result[j][3].toString());
Marker newmarker = new
Marker(LatLng.newInstance(lt, ln), mo);
mapWidget.addOverlay(newmarker);
newmarker.addMarkerClickHandler(new
MarkerClickHandler() {
So I have a click handler on all of those guys but when clicked I need
somehow distinguish between them.
I think that getting the coordinates of clicked marker would be a good
Idea as it's unique so I can query database an produce report for that
particular location.
But I have no idea how to start.
When I try this:
newmarker.getLatLng();
I get following error:
Cannot refer to a non-final variable newmarker inside an inner class
defined in a different method
Anyone knows how to do that ?

Peter
