Android Question Dynamic content in InfoWindowAdapter - how to?

[ThePuiu]

I want that when the user clicks on an existing marker, download some information from the server and display it in InfoWindowAdapter. I don't know how to fill in InfoWindowAdapter with the data returned from the server...
I use the code:

Sub MapFragment1_Ready
    gmap = MapFragment1.GetMap
    rp.CheckAndRequest(rp.PERMISSION_ACCESS_FINE_LOCATION)
    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
    If Result Then
        gmap.MyLocationEnabled = True
    Else
        Log("No permission!")
        Return
    End If
    
    Dim extra As GoogleMapsExtras
    Dim iwa As InfoWindowAdapter
    iwa.Initialize("iwa")
    extra.SetInfoWindowAdapter(MapFragment1.GetMap,iwa)
      
    MapPanel.Initialize("")
    Activity.AddView(MapPanel, 0, 0, 300dip, 300dip)
    MapPanel.LoadLayout("itemMarkerHarta")

    MapPanel.RemoveView
End Sub
......
Sub iwa_GetInfoContents(Marker1 As Marker) As View
    GetInfoMarker(Marker1.Snippet)  
    
    LabelInfo1.Text = ?????

    Return MapPanel
End Sub
......
Sub GetInfoMarker(aidiMarker As String)
    Dim jobDownload As HttpJob
    jobDownload.Initialize("jobLoadInfo", Me)
    ProgressDialogShow2("Operatie in progres...", False)
    
    ................................. reading data from server .....................................................

    ProgressDialogHide
    jobDownload.Release()

End Sub

You must download the data before the GetInfoContents event is raised.

in which event should I call the download function for the selected marker?
iwa_GetInfoContents(Marker1 As Marker) As View it is called only in Release mode and I cannot understand the flow of the application...

You cannot make a http request in GetInfoContents as it expects the view immediately.

You will need to download the data before it is requested by Google Maps.

I understand that the data must be available before the InfoWindowAdapter is displayed, but in my case there is a large number of markers and the information to be displayed for each of them changes from minute to minute ...

You can handle the Marker click event, download the data and then show the info window.
