Activity.AddView in Listview

[R1cky]

Hi!!
I'm a real beginner!!

I have i problem on my code.
-There is a service that wait sms with SMSinterceptor
-The Sub _MessageReceived in the Main read the number and if this match add this number to a listview.

All work, I can select form listview some item too, but when i change orientation the listview lost all text.
The only one difference with all examle si the position of .AddSingleLine(sometinig), mine is inside _MessageReceived sub.

Thank you very much!

Regards
Rick

'Activity module
Sub Process_Globals
   'These global variables will be declared once when the application starts.
   'These variables can be accessed from all modules.
   Dim notification1 As Notification
   Dim SI As SmsInterceptor

End Sub

Sub Globals
   'These global variables will be redeclared each time the activity is created.
   'These variables can only be accessed from this module.
   Dim Numero As Label
   Dim Testo As Label
   Dim Elencosms As ListView
End Sub

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("GUIsms")
   SI.Initialize("SI")
   Elencosms.Initialize("Elencosms")
   Activity.AddView(Elencosms, 0, 0, 100%x, 100%y)
   End Sub

Sub Activity_Resume
   
End Sub

Sub Activity_Pause (UserClosed As Boolean)
   
End Sub


Sub SI_MessageReceived (From As String, Body As String) As Boolean
'   ToastMessageShow(From, True)
   If From = "+0123456789" Then
   Numero.text = From
   Testo.text = Body
   End If
   Elencosms.AddSingleLine(Body)
   Return True
   End Sub
Sub Elencosms_ItemClick (Position As Int, Value As Object)
    Testo.text = Value
End Sub

You could save the "From" and "Body" to a file (or maybe a MySQL DB) before adding them to the ListView, and repopulate the ListView reading the info in Activity_Resume.

I think you should store any data received, in a file, from which you should restore once the activity_resume event is triggered by an orientation change.

note: just saw NJDude's reply, sorry I was writing at the same time

Thanks mc73 and NJDude for answer!
But why in simple listview code work without problem and no store data is needed?

   For i = 1 To 500
      ListView1.AddSingleLine("Item #" & i)
      ListView1.AddTwoLines("Item #" & i, "This is the second line.")
      ListView1.AddTwoLinesAndBitmap("Item #" & i, "This is the second line.", Bitmap1)

Because when the orientation changes, the activity is destroyed and re-created.
So the code in Activity_Create runs again.
