Not so simple but possible. Create the second layout off screen, take a snapshot and then draw it with this animation effect.

Thanks

but, how can I draw it by animation?

You need to implement it yourself. I would have done it with BitmapCreator and a loop with a call to Sleep.

Test it in Release...

I have tested it(not worked), And this is my code :

Sub drawWithAnimatoin
  
    Dim bc As BitmapCreator
    Dim brush As BCBrush
  
    bc.Initialize(100%x, 100%y)
    Dim bmp As B4XBitmap = Root.Snapshot
    brush = bc.CreateBrushFromBitmap(bmp)
    Root.Color = Colors.White
  
    For i=0 To Panel1.Height
      
        bc.DrawCircle2(200dip, 200dip, DipToCurrent(i), brush, True, 10dip)
      
        Panel1.SetBackgroundImage(bc.Bitmap)
      
        Sleep(0)
    Next
  
  
End Sub
