Set the button to invisible at designtime

B4X:

Sub EditText1_TextChanged (Old As String, New As String)
    If New.Trim <> "" Then
        Button1.Visible = True
    Else
        Button1.Visible = False
    End If
   
End Sub

It works great thanks
Now I have to combine
so that the entry in activity 1
caused the activation button on the activity of 2

This will also work:

B4X:

Sub EditText1_TextChanged (Old As String, New As String)
        Button1.Visible = New.Trim <> "" 
End Sub
