Hi there.

I would like to know if it is possible to have a progressbar on my app (tablet based) where it will incremente smoothly for 5 seconds for example.

This app refresh data each 5 seconds and I would like to give a feedback to the user.

I have already a timer that ticks every 5 seconds for the update.

Any ideas?

Thank you

B4X: 
Sub SetProgressSmoothly(PB As ProgressBar, Target As Int, Duration As Int)
   Dim n As Long = DateTime.Now
   Dim start As Int = PB.Progress
   Do While DateTime.Now < n + Duration
     PB.Progress = start + (Target - start) * (DateTime.Now - n) / Duration
     Sleep(10)
   Loop
   PB.Progress = Target
End Sub

Usage example:
B4X: 
Sub Activity_Click
   SetProgressSmoothly(ProgressBar1, 100, 5000)
End Sub
