Sub Activity_Create(FirstTime As Boolean)
'Do not forget to load the layout file created with the visual designer. For example:
'Activity.LoadLayout("Layout1")

For i = 0 To 7
btn(i).Initialize("btn")
Activity.AddView(btn(i),5%x,15dip + i*75,80%x,60dip)

Fixed. Try this code:

For j = 0 To 7
        k = Rnd(0, 8)
        btn(j).TextColor = Colors.Blue
        btn(j).TextSize = 18
        btn(j).SetBackgroundImage(LoadBitmap(File.DirAssets,k & ".png"))
        btn(j).Text = k
    Next

@juniorteacher if this is the same problem as you previously posted where you want unique and random values then I suggest that you add each image and text to a list and randomly remove from the list and assign to each button as previously suggested. Trust me, it will be far simpler. Have a go and if you encounter problems I'll help.
