方法裏的類找不到遇到的2個錯誤

今天在一個類裏寫一個方法，定義一個String token="";之後的回調函數裏面找不到這個token，報錯：Cannot refer to a non-final variable vote inside an inner class defined in a different method。好吧，我加上final定義一個final String token="";報錯：The final local variable vote cannot be assigned, since it is defined in an enclosing type 查了下，看到有人碰到過，鏈接https://stackoverflow.com/questions/21485590/the-final-local-variable-cannot-be-assigned-since-it-is-defined-in-an-enclosing 怎麼解決掉呢？簡單，final String[] strToken = { "" }; 拿的時候，用strToken[0]就好。
