Android Question GMAPS click problem

[FrankBerra]

Hi all

I am using google maps in my app. everything works correctly until i open the map again.

Here the code i use to open the map when i click on a button:

Sub Impostazioni_Button_VisualizzaZoneInvisibilita_Click

    FinestreVisualizzate.InsertAt(0,"Impostazioni_ZoneInvisibilita")
    ScrollViewPannelloCentrale.Panel.RemoveAllViews '
    ScrollViewPannelloCentrale.ScrollToNow(0)
    ScrollViewPannelloCentrale.Panel.LoadLayout("Impostazioni_ZoneInvisibilita")
    ScrollViewPannelloCentrale.Panel.Height = 100%y-100dip
   


               
   If Impostazioni_ZoneInvisibilita_Mappe.IsInitialized Then
       Impostazioni_ZoneInvisibilita_Mappe.Color=Colors.White
       If mFragment_Invisibilita.IsGooglePlayServicesAvailable = False Then
          ToastMessageShow("Google Play services not available.", True)
       Else
          mFragment_Invisibilita.Initialize("MapInvisibilita", Impostazioni_ZoneInvisibilita_Mappe) 
       End If
  
   End If
           
End Sub

And this is the remaining code for let it working:

Sub MapInvisibilita_Ready
   'Log("map ready")
   gmap_Invisibilita = mFragment_Invisibilita.GetMap
   If gmap_Invisibilita.IsInitialized = False Then
      ToastMessageShow("Error initializing map.", True)
   Else
     

       gmap_Invisibilita.AddMarker(Latitudine_Invisibilita, Longitudine_Invisibilita, "")
     Dim cp As CameraPosition
      cp.Initialize(Latitudine_Invisibilita, Longitudine_Invisibilita, 15)
      gmap_Invisibilita.MoveCamera(cp)
     gmap_Invisibilita.MyLocationEnabled=False
     'gmap.AnimateCamera(cp)
     
     
   End If
End Sub


Sub MapInvisibilita_Click(Point As LatLng)
    PuntoInvisibilita = Point 
    Impostazioni_ZoneInvisibilita_SeekBarRaggio.Enabled = True '
    ToastMessageShow("Point: " & Point.Latitude & ", " & Point.Longitude,False)
    gmap_Invisibilita.Clear
    Dim Acc As Float = 200
            Dim GoogleMapsExtras1 As GoogleMapsExtras 'https://www.b4x.com/android/forum/threads/google-maps-android-v2-tutorial.24415/page-3
            Dim circle As CircleOptions
            circle.Initialize
            circle.Center2(Point.Latitude, Point.Longitude)
            circle.Radius(Acc)
            circle.StrokeWidth(2)
            circle.StrokeColor(Colors.ARGB(255,15,157,88))
            circle.FillColor(Colors.ARGB(50,15,157,88))
            GoogleMapsExtras1.AddCircle(gmap_Invisibilita,circle) 
End Sub

Well if i click on the button for opening the maps everything is working correctly and the circle is added on maps when i tap on maps.
If i click again on the button, the maps displays correctly and i can zoom-in/out but the sub MapInvisibilita_Click is not raised anymore if i tap on the map.

So why happening that?
The situation is back to normal if i close and then open the app. But of course repeating the steps above the problem occours again

Any suggestions?
Thanks in advance!

Assuming that you are using GoogleMaps v2 then you need to add the map with the designer. Add it to a panel and hide or show the panel when needed.
