Zmienne się nie aktualizują czasami

Question

Witam jestem początkującym programistą w androidzie z javą i mam problem z zmiennymi .

Problem polega z Zmiennymi Wyb1,Wyb2 oraz Wyb3 do którym jest przypisane wypisanie zmiennej numberasString 

problem z moim kodzie polega iż czasami ponowne wykonanie Do() Zmienne te nie wypisują zaktualizowanych liczb

przypisanych po nich po wykonaniu obliczeń
