iOS Question [B4X] how to get a xCustomListView from a container if it was generated dynamically

[Alexander Stolte]

I have a form with a xCustomListView, I now add this form to another xCustomListView as an item.
How can I access this dynamic added xCustomListView now?

This is not working:

As these conventions are rather new, they are not used by some popular custom views such as xCLV. You can set the base panel tag yourself in such cases. For example:

Activity.LoadLayout("1")
clv.AsView.Tag = clv
'now we can get the clv with:
Dim c As CustomListView = Activity.GetView(<clv index>).Tag

For i = 0 To 10 -1
Dim xpnl_vertical As B4XView = xui.CreatePanel("")
xpnl_vertical.SetLayoutAnimated(0,0,0,100dip,100dip)
xpnl_vertical.LoadLayout("frm_preview_item_1")
      
Dim xclv As CustomListView = xpnl_vertical.GetView(0).tag
xclv.AsView.Tag = xclv

xclv_global.Add(xpnl_vertical,"")
Next

Add a global CustomListView variable with the same name as the CLV from the layout file:

xpnl_vertical.LoadLayout("frm_preview_item_1")
MyCustomListView.AsView.Tag = MyCustomListView
