Android Question GoogleMap library, loop throught markers

[marcick]

Hi,
is it possible to query the map and obtain a list of all markers that have been placed and know the title and coordinate of each one ?
Or, again, is it possible to know if a marker with a certain title exist on the map ?

Each time you add a marker, add it to a List. You will then be able to check their status.

I'm still confused on the correct approach to this library.
Suppose I have to place on the map 50 markers, each one has a different icon, position and a unique title.
Non I want to change something on the marker that has the title "bob".
Do I have to clear all the map and redraw all 50 markers, using the method of the list that you suggest ?
Do I have to create each marker with its own global variable ? (Dim Marker1, Marker2 .....Marker50 As Marker)

(Dim Marker1, Marker2 .....Marker50 As Marker)

It is never a good idea to create such variables.

You can use a Map to map between the marker "name" and the marker.

For example:

Sub AddMarker(Name As String, Text, ...)
  Dim m As Marker = gmap.AddMarker(...)
  MapOfMarkers.Put(Name, m) 'global variable
End Sub

Now you can get any marker you like.
