Hello, I'm currently having issue using Customlistview. I'm still studying how it works.
I'd like to add pictures thumbnails to a customlistview but I'am having error when adding them at line 28.
This is the log:

required: customlistview,B4XViewWrapper,Object
found: B4XViewWrapper,Object
reason: actual and formal argument lists differ in length

B4X:
#Region Project Attributes
    #MainFormWidth: 600
    #MainFormHeight: 600
#End Region

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private xui As XUI
    Private clv As CustomListView
    Private ImageView1 As ImageView
    Private Label1 As B4XView
    Private txt As String
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("MainPage")
    MainForm.Show
    Dim images As List
    images.Initialize
    
    For Each f As String In Array("1.png","2.png","3.png","4.png")
        images.Add(xui.LoadBitmapResize(File.DirAssets,f,100dip,100dip,True))
    Next
    txt="Image text"
    For i = 1 To 20
        clv.Add(CreateItem(images.Get(i Mod images.Size),txt),txt) 'PROBLEM HERE'
    Next
End Sub

private Sub CreateItem (img As B4XBitmap, txt1 As String) As B4XView
    Dim p As B4XView= xui.CreatePanel("")
    p.SetLayoutAnimated(0,0,0,100dip,120dip)
    p.LoadLayout("ItemLayout")
    ImageView1.SetImage(img)
    Label1.Text=txt1
    Return p
End Sub

For me it's ok !
The reason it is working for you is because you are only using the class module and you did not put a check for the xCustomlistview library. You have to use either one, but not both. Preferably, you want to use the library instead of the class module.
