Android Question No Images shown in customlistview

[ViMeAv ICT]

I use the following code but get no images in the customlistview.
What am I doing wrong?

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Layout1")   
    For i = 0 To 10
        MainList.Add(MainItem,"Main Group")
    Next
End Sub

Sub MainItem As B4XView
    Dim p As B4XView = xui.CreatePanel("Panel")
    p.SetLayoutAnimated(0,0,0,MainList.AsView.Width,MainList.AsView.Height/4)
    Dim bmp As B4XBitmap = xui.LoadBitmapResize(File.DirAssets, "1.jpg", MainList.AsView.Width,MainList.AsView.Height/4, False)
    p.SetBitmap(bmp)
    ''p.Color = Rnd(0xff000000, 0xffffffff)
    Return p
End Sub

you have to use p.LoadLayout("layout")

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    
    Private MainList As CustomListView
    Private Label1 As Label
    Private ImageView1 As ImageView
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Layout")
    For i = 0 To 10
        MainList.Add(MainItem("legend",i), "")
    Next
End Sub

Sub MainItem(txt As String, n As Int) As B4XView
    Dim p As B4XView = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0, 0,MainList.AsView.Width,MainList.AsView.Height/4)
    p.LoadLayout("img")
    Label1.Text = txt&" - "&n
    ImageView1.Bitmap = xui.LoadBitmap(File.DirAssets,"1.jpg")
    Return p
End Sub

Ok, I had seen this before. You need an extra layout. Thanks!
But I have another question, concerning the layout.
How can I arrange the customlist the way it shows 4 pictures at a time, completely filled the customlist.
(even by using pictures with different sizes)
See picture please.
