Android Question TextChanged on TextFieldAdvanced

[mayahandayani]

hallo I used this to fill phone number :

[B4X] [XUI] AS TextFieldAdvanced - Title, Information, Counter, Password, Button, Prefix, Suffix, Icons, Multiline

With this view you can quickly and easily add good looking text fields, with title and or bottom text. Additionally you can make the TextField a button, so that you can open menus, but still keep the design of the text fields. The view speeds up development because you don't have to worry about...

On _TextChanged, I want to know the new & old text. Is that possible? If yes, how to do that?

Thanks

Sub EditText1_TextChanged (Old As String, New As String)
    If ContieneCaratteriNonConsentiti(New) Then
        EditText1.Text = Old ' 🔁 Ripristina il testo precedente
        ToastMessageShow("Carattere non valido!", False)
    End If
End Sub

' Funzione di esempio che controlla simboli vietati
Sub ContieneCaratteriNonConsentiti(testo As String) As Boolean
    Dim pattern As String = "[^a-zA-Z0-9 ]" ' Solo lettere, numeri e spazi
    Dim m As Matcher
    m = Regex.Matcher(pattern, testo)
    Return m.Find
End Sub
