Question

I need to display an additional info for a marker when it’s clicked. I expected to find a way how to display a popup window (like a tooltip) with a short description on marker click, but failed.
I use MapMarker class for my markers because I need custom icons.
The MapMarker and MapStandardMarker classes do not have the functionality I need.

As I understand, I need something like Android MapView Balloons

I’ve solved the problem.
I use the popup dialog similar to the one implemented in “Meet Me For Dinner” sample application. All necessary info can be found here.

I met the problem with detecting a click on marker. For this I used MapDisplay.getObjectAt () method. But it looks like that method doesn’t take into account the marker’s anchor point. So, I had to use the following work-around for this:

    final MapObject mapObj = mapDisp.getObjectAt ( new Point (
    clickX + m_markerIconSize.getWidth (),
    clickY + m_markerIconSize.getHeight () )
);
if ( (mapObj != null) && (mapObj instanceof MapMarker) ) {
