Dim Bm1 As Bitmap = LoadBitmap(File.DirAssets,CurrLng.ToLowerCase & ".png")
Dim Bm2 As Bitmap = LoadBitmap(File.DirAssets,"caller_off.png")
Dados.Add(CreateListItem(Bm1,Bm2,"Pedido : " & NumPed & " - Pessoas : " & NumPax, DataPed & " - " & HoraPed,Dados.AsView.Width, 70dip), 70dip, "")

Sub CreateListItem(Imagem1 As Bitmap, Imagem2 As Bitmap ,Text1 As String, Text2 As String, Width As Int, Height As Int) As Panel
    Dim p As Panel
    p.Initialize("")
    p.SetLayout(0, 0, Width, Height)
    p.LoadLayout("CellItem")
    lbl1.Text = Text1
    lbl2.Text = Text2

    ImgView.Bitmap = Imagem1
    ImgView.Width = Height - 5
