pomoc oko Adressbook

Imam problem sa upisivnjem podataka u ListView

kada pokrenem program izbaci mi sledecu gresku (Object reference not set to an instance of an object.)

a sta je najveca fora kada sam upisao jedno ime u imeniku u upise u XMLu ali nece u Listview

ako neko hoc mogu da mu posaljem izvrsni code pa da isproba da resi muku

Inace sam pocetnik tako da bi mi mnogo pomogli.

Greska koju dobijas znaci da imas neku
promjenljivu koja je null jer vjerovatno nisi
instancirao objekat sa new.
Posalji ovdje dio koda na koji sumnjas pa da pogledamo
