Android Question Dynamically resize a label

[KDHeard]

Hi all - I am attempting to resize a label in Activity_Create through a loop with a timer and am up a creak without a paddle but with lots of noobness.... for some reason I cannot get the timer to work. Has anyone tried something similar? The overall idea is to create the feel that the label is appearing out of nothing.

My code is below.

Sub Process_Globals
      Dim Timer1 As Timer
    Dim ButtonWidth As Int
End Sub
 
Sub Globals
    Dim Label1 As Label   
End Sub
 
Sub Activity_Create(FirstTime As Boolean)
   
    Activity.LoadLayout("FiveWhyMain")
   
    Dim UnitWidth As Int
    Dim GapWidth As Int
   
    UnitWidth = GetDeviceLayoutValues.Width / 6
    GapWidth = UnitWidth / 6
   
    'Scale up buttons
        Timer1.Initialize("Timer1",1000)
        Timer1.Enabled = False
        Timer1.Interval = 1000
       
    Do While ButtonWidth < UnitWidth
        Timer1.Enabled = True
        Timer1_Tick
        Timer1.Enabled = False
    Loop   
 
      If ButtonWidth < UnitWidth Then
        Return
    End If
   
End Sub
 
Sub Timer1_Tick
 
    ButtonWidth = ButtonWidth + 1
    Label1.Width = ButtonWidth
   
End Sub

Why not use the Animation library for that?

It will be simpler and smoother.

Hi Erel - thanks for your suggestion. I will definitely explore the module. Being a noob (and totally enjoying it) B4A is providing quite a steep learning curve.

Thanks

If you were to use such code, I think that it should look like this:

    ...
    'Scale up buttons
        Timer1.Initialize("Timer1",1000)
        Timer1.Enabled = True
        ' Timer1.Interval = 1000 -- Not needed; you set it in Initialize.
        ' Note: 1000 = 1 second, which is a pretty slow step time for this.
End Sub

Sub Timer1_Tick
    If Label1.Width < UnitWidth Then
        Label1.Width = Label1.Width + 1 ' 1 is a pretty small step. Might try 10 or more.
    Else
        Timer1.Enabled = False
    End If
End Sub
