Jestem nowością w Androidzie i całkowicie związałem moją aplikację, ale chcę teraz ją zmienić.

Gdy ktoś wysyła sms, chcę wyświetlić okno dialogowe potwierdzenia wysyłania smsów z prośbą o wysłanie lub nie. I muszę stworzyć wspólną klasę, dla której napisałem kod źródłowy i działa dobrze, ale jeśli użytkownik nie kliknie Tak lub Anuluj, okno dialogowe gaśnie, ale chciałbym, aby nadal wyświetlało się, dopóki użytkownik nie kliknie Tak lub Przycisk Anuluj.

Jak można to rozwiązać?
