I am displaying a few location on map using RichMapField,  MapLocation, and MapDataModel (BlackBerry JDE 6.0.0).

How I can capture click or touch on location pin/marker to go to the detail screen?

How can I display user's current location using different pin (to distinguish from other markers)?

Is that possible, or should I use different approach?

Thanks,

Boogy

Welcome to forums. Have you tried searching on forums? I remember there were some discussions on what you are trying to achieve including some example code.

I did try searching, but no luck.

If anybody knows where is the good answer, please post a link!

Thanks,

i think you can reference this link http://supportforums.blackberry.com/t5/Java-Development/How-to-display-multi-cursors-on-the-google-m...

There is API´s to have different marker.. But you can try extending the RichMapField and add your own marker.. But I think it might be complex if you have many pointers (when you want to show each with different representation)

To capture the touch on location , may be you can try to make use of the API 

convertWorldToField() , which converts the coordinates to Pixels to place it on the screen...

(Note : I have not tried it.. Just this will be the first one I will experiment with when hearing your requirements..)

Thanks sheeluwiki,

I believe your answer leading in good direction, but a few more questions:

what RichMapField's property to use to set icon used for marker?

Should I overwrite touch event, do you have any sample code for that?

Thanks!

RichMapField extends MapField..

May be you can override the paint() method for the customerized marker purpose.. The below code snippet can be used for reference.. But I am not sure if this is the correct method to be overriden..

 protected void paint(Graphics graphics) {
        super.paint(graphics);
                if(myLocation != null) {

                       Coordinates co = mapField.getCoordinates();
                       co.setLatitude(Double.parseDouble(myLocation.getLat()));
                       co.setLongitude(Double.parseDouble(myLocation.getLng()));
                
                        XYPoint point = new XYPoint();
                        mapField.convertWorldToField(co, point);
                
                       Bitmap bitmap = Bitmap.getBitmapResource(myLocation.getImageName());
                       graphics.drawBitmap(point.x, point.y, bitmap.getWidth(), bitmap.getHeight(), bitmap, 0, 0);

              }

  }

Please also look into below URLs for API reference..

I think you have to override the touchevent() of the Mapfield to capture your touch events..

using RichMapField and MapLocation, on the map is showed automatically a baloon with the info of location added. I need to know when the user click on this ballon or touch. How can I catch this event ?
