it's my code as below

Private Sub Application_Start (Nav As NavigationController)
    NavControl = Nav
    Page1.Initialize("Page1")
    Page1.RootPanel.LoadLayout("Main")
    NavControl.NavigationBarVisible=False
    NavControl.ToolBarVisible=False
    NavControl.ShowPage(Page1)
    mylist.Initialize
    stepno=1
   
   
End Sub

Private Sub CreateItem(ShowText As String,FileName As String) As Panel
    Dim p As Panel
    p.Initialize("")
    p.Width = 100%x
    p.Height = tv.RowHeight
    p.LoadLayout("1")
    Label1.Text=ShowText
    ImageView1.Bitmap=LoadBitmap(File.DirAssets,FileName)
    ImageView1.Tag=ShowText
    Return p
End Sub

Sub New_Click
    Dim i As Int
    If mylist.Size=0 Then
        mylist.Add("B" & stepno)
    Else
        mylist.Add("B" & stepno)
    End If
    show
    tv.ReloadAll
    tv.SizeToFit
End Sub
Sub show()
    tv.Initialize("tv", False)
    Panel1.AddView(tv, 0, 0, 100%x, 100%y)
    tv.RowHeight = 50 'must set RowHeight before adding custom views.
    For i=0 To mylist.Size-1
        Dim tc As TableCell = tv.AddSingleLine("")
        tc.ShowSelection = False
        Dim a As Int=i+1
        tc.CustomView = CreateItem("B" & a,"safari.png")
        stepno=stepno+1
    Next
   
End Sub

but I don't know why there are just show one single data of first I inserted?

I recommend you to use xCustomListView instead. It will be simpler and more flexible.

If mylist.Size=0 Then
mylist.Add("B" & stepno)
Else
mylist.Add("B" & stepno)
End If

What is the purpose of this code?

You are adding items to mylist instead of tv.

mylist is used be extended to another purpose,


but I do additems in to tv

Sub show()
    tv.Initialize("tv", False)
    Panel1.AddView(tv, 0, 0, 100%x, 100%y)
    tv.RowHeight = 50 'must set RowHeight before adding custom views.
    For i=0 To mylist.Size-1
        Dim tc As TableCell = tv.AddSingleLine("")
        tc.ShowSelection = False
        Dim a As Int=i+1
        tc.CustomView = CreateItem("B" & a,"safari.png")
        stepno=stepno+1
    Next
  
End Sub

but I don't know why there are just show one single data of first I inserted?


btw,is there any sample project with xCustomListView?

You shouldn't initialize and add the TableView each time. Add it once as a custom view with the designer (make sure to use iUI8 library and NOT iTableView).

Example based on the old CustomListView: https://www.b4x.com/android/forum/threads/class-customlistview.46560/#content
It should be trivial to change it to work with xCustomListView.
