Android Question Wait progress bar

[luciano deri]

Is there something like this in B4A?
https://www.b4x.com/android/forum/threads/b4x-resumable-subs-sleep-wait-for.78601/page-2#post-499400
I need a panel with progress bar o progress dialog to show up during a any long elaborations.
I try to do this but i have difficult to show progress (Doevents, sleep(0), waith for?) and intercept the press on button to interrupt elaboration.
Thank you very much

Start with the code I posted in the other thread:

    ProgressDialogShow("Lettura tabella in corso")
    For i = 0 To dbcursor.RowCount - 1
        dbcursor.position = i
        If i Mod 500 = 0 Then Sleep(0)
        Do something ...
    Next
    ProgressDialogHide

Does it work for you?

 

[luciano deri]

No, is not right. Could you look this please?

It doesn't work because you have put it in the wrong place. The long loop is in StartIC_Click.

You need to add it there:

For i = 0 To 10000
   Log(i)
   NOISE.NoiseNext
   If NOISE.Interrotto Then
     Exit
   End If
   If i Mod 500 = 0 Then Sleep(0)
Next

With that said, your code looks wrong and more complex than it should be.

Why are you calling NoiseNext from the loop? It is called by the timer.

I've created a simple custom view that shows an animated gif.

Ok, we are almost there.
NoiseNext is call in cicle because noise is initialize without timer. It do so to sincronize gif rotation with to process flow.
When noise not work with the timer i can not stop process rightly.
See the attach.
How can integrate it with https://www.b4x.com/android/forum/threads/custom-view-gifviewer.82104/ ?
It can work faster?
Thank you very much
