How to access edittext again?

Hi Klaus,
After I use this below:-
Dim obj1 As Reflector
obj1.Target = EditText1
obj1.RunMethod2("setFocusable", "False", "java.lang.boolean")
I need access EditText1 again,I tried to add this code in procedure EditText1_Focus(HasFocus as Boolean) :-
Dim obj1 As Reflector
obj1.Target = EditText1
obj1.RunMethod2("setFocusable", "True", "java.lang.boolean")
I can't Access ??
