Jak rozwiązać błąd jak java.lang.Throwable: setStateLocked?

Question

Pracuję nad aplikacją. W tym używam listview. Kiedy klikam element listy, powinien przejść do następnej aktywności, np. ProfileActivity2.java. Działa to dobrze, ale w tym ProfilAktywistyka2 znajduje się przycisk na dole, a kiedy klikam ten przycisk, moja aplikacja ulega awarii i zatrzymuje się na stronie listy. I pokazuje błąd java.lang.Throwable: setStateLocked w pliku układu listy, np. SetContentView. Jak rozwiązać ten błąd?

Answer 1

context.startActivity(intent); 

Myślę, że błąd jest na tej linii wewnątrz btn.setOnClickListener bloku getview wystarczy użyć startActivity(intent);
