Android Question why marker properties does not change ?

[marcick]

In this code, I see the changes in the log, but nothing happens on the map.
Also Marker1.remove or any other action on the marker has not effect
Where I'm wrong ?

Sub Mapfragment1_MarkerClick (Marker1 As Marker) As Boolean
      
    Log(Marker1.Snippet)
    Marker1.Snippet="new snippet"
    Log(Marker1.Snippet)
 ''   Marker1.remove 
   
   Return True
  
End Sub

Try Mapfragment1_MarkerClick (SelectedMarker As Marker) As Boolean

....
the MarkerClick event already contains the selected marker, you can call it "marker1", "selectedmarker", there is no difference
Am I wrong ?

I have tried your example. It works as it should...

Sub Activity_Create(FirstTime As Boolean)
   MapPanel.Initialize("")
   Activity.AddView(MapPanel, 0, 0, 100%x, 100%y)
   If mFragment.IsGooglePlayServicesAvailable = False Then
      ToastMessageShow("Google Play services not available.", True)
   Else
      mFragment.Initialize("Map", MapPanel)
   End If
End Sub

Sub Map_Ready
   Log("map ready")
   gmap = mFragment.GetMap
   If gmap.IsInitialized = False Then
        ToastMessageShow("Error initializing map.", True)
   Else 
        Dim MarkerOptions1 As MarkerOptions
        MarkerOptions1.Initialize

        Dim Marker1 As Marker
        Dim Marker2 As Marker
        Marker1= gmap.AddMarker( 64.47619, 18.3980,"pkt1") ',LoadBitmap(File.DirAssets, "icon1.png")) ' Ok so far
        Marker1.Snippet= "pkt1"
        MarkerOptions1.Position2(64.99619, 17.3980).Snippet("pkt2").Title("pkt2")
        Marker2=GoogleMapsExtras1.AddMarker(gmap, MarkerOptions1)    
 
        Dim cp As CameraPosition
        cp.Initialize(64, 18, gmap.CameraPosition.Zoom)
        gmap.AnimateCamera(cp)
   End If
End Sub
Sub Map_MarkerClick (SelectedMarker As Marker) As Boolean 'Return True to consume the click
    Log(SelectedMarker.Snippet)
    SelectedMarker.Snippet="new snippet"
    Log(SelectedMarker.Snippet)
    'Return True
End Sub

thanks, let me check where I'm wrong and I'll come back.

It works ...
After changing the snippet, there was another wrong part of code that restored the old snippet, so I didn't see the difference.
ANyway you can call it "SeelectedMarker" or "MyMarker" that it works.
Thanks Croid and Eurojam, bye
