B4J Question Gmap Market Position Change

[tufanv]

Hello,

I am getting the lat,lon from my database for 100 cars. At first load, I add the markers for these 100 cars, and all cars have an unique id. Later, every 1 minute I load the lat,lon of each car again from the database and I need to change the marker position of each car for their new position. My problem here is, I can't match the newly recieved data to old created markers. For example with first load I add the marker for car : abcd and with second load when i get the new lat lon , I need to change the marker of abcd with marker.position but I don't know how can I change the correct marker which is created at first load for abcd.

Whıch way is the best to achieve this ?

Thanks

1. Create a Map
2. Add a Marker at begin and put the marker into the map using their unique id as key as the marker as Value. do this for all 100 Cars.
3. Reload the positions.
4. Iterate through all cars, get the marker from the map. Set the new position to the marker.

Thanks ! I tried list but as I cant read the title ( it is for setting only not getting) I couldnt do it. You are right map can solve this. Thanks
