jak pozwolić, aby ten stan przycisku został zapisany i użyty we wszystkich moich działaniach przy użyciu współdzielonych preferencji, umieściłem kod współdzielonych preferencji, ale ten nie działa, więc czy jest coś, czego brakowało lub ten kod jest błędem

to jest nowy kod i cały kod klasy, proszę to sprawdzić, może coś wpłynie na kod
