Did you create it in the designer or in code? The FocusChanged event must match the event name property. This is mostly automatic in the designer but not in code.
When you add views in the code you must declare then in Globals as you did. Dim edtPilot1 As EditText
Then you must initialize it as suggested by margret. edtPilot1.Initialize("edtPilot1")
And you must add it to the Activity or a Panel. Activity.AddView(edtPilot1, 10dip, 10dip, 150dip, 50dip)
AddView(View, Left, Top, Width, Height)
If the EditText view already has the focus and you touch it the event is not fired.
