This is an example of how you can customize a Map.
Through the B4XCanvas functions it is possible to create the map with photos, text, etc.
The classes used are MapScale + GoogleMapsExtra (https://www.b4x.com/android/forum/threads/class-googlemapsextra.56871/)

The following code is an example for B4i but can also be extended to B4A and B4J.

You are show me a BXi Sample, I know that this works on iOS, the problem is in BXa

This will show your form inside the tipically infowindow. :(

Andy suggestion??
Thanks

Nicolas as write #1 Post "can also be extended to B4A and B4J".
Here a little, dirty and fast example in B4A with Infowindow

You have this effect:

Library GoogleMaps , GoogleMapsExtras, JavaObject, xui view, RuntimePermission, ( if you want maps without Poi )

B4X:
Sub Process_Globals
    Private rp As RuntimePermissions
End Sub

Sub Globals
    Private gmap As GoogleMap
    Private MapFragment1 As MapFragment
    Dim xui As XUI
    Dim InfoWindowPanel As Panel
    Dim gextra As GoogleMapsExtras
    Dim MapPanel As Panel
    Private Label1 As Label
    Private ImageView1 As ImageView
End Sub


Sub InfoWindowAdapter1_GetInfoContents(Marker1 As Marker) As View

    '   the default InfoContent will be used if this event Sub is not defined or if it returns Null
    Log("InfoWindowAdapter1_GetInfoContents")
    
    Dim splitta() As String = Regex.Split("\|", Marker1.Title)
    
    Label1.Width = 120dip
    Label1.Text = splitta(0)
    
    Dim img As B4XBitmap = xui.LoadBitmapResize(File.DirAssets, splitta(1)&".jpg", 60dip, 60dip, True)
    ImageView1.Bitmap = img 
  
    Return InfoWindowPanel
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("1")
    
    If MapFragment1.IsGooglePlayServicesAvailable = False Then
        ToastMessageShow("Google Play services not available.", True)
    Else
        MapFragment1.Initialize("MapFragment1", MapPanel)
    End If
    
    
    Wait For 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
    
        '***For Photo & Text
        Dim GoogleMapsExtras1 As GoogleMapsExtras
        Dim InfoWindowAdapter1 As InfoWindowAdapter
              
        InfoWindowAdapter1.Initialize("InfoWindowAdapter1")
        GoogleMapsExtras1.SetInfoWindowAdapter(gmap, InfoWindowAdapter1)
      
                
        InfoWindowPanel.Initialize("InfoWindowPanel")
        InfoWindowPanel.LoadLayout("lay_info")

        'a hack(ish) way to set InfoWindowPanel width and height!
        MapPanel.AddView(InfoWindowPanel, 0, 0, 200dip, 60dip)
        InfoWindowPanel.RemoveView
    
        'Click  Photo & Text
        Dim icl As OnInfoWindowClickListener
        icl.Initialize("InfoWindowClick")
        gextra.SetOnInfoWindowClickListener(gmap, icl)
        '***End Photo & Text
    
            
    'Type Maps
    gmap.MapType = gmap.MAP_TYPE_NORMAL
    
    'Get lat e lon 
    Do While gmap.MyLocation.IsInitialized = False

Thanks Marco,

But even in your example, the typical infowindow is visible.

What I require is that this infowindow is not visible and that the panel looks like flying, by itself.

In other words, the traditional infowindow looks transparent.

Thanks.

Yes, I got to the same links, I have already reviewed all of them, but I have not been able to implement it in "B4A"
