我有36個按鈕（我在這個問題中只顯示2）在活動Pim。每個按鈕在我的共享首選項中分配/保存一個密鑰，這些密鑰在活動S1m中加載，但問題是它從不加載我的密鑰。共享偏好不會加載在Android

我的按鈕做工精細，因爲總是顯示爲它們分配吐司。
在P1m中，每次創建按鈕時都會創建SharedPreferences即時變量。在onCreate（）期間只創建SharedPreferences和Editor變量一次，並在onClick（）方法中使用它們來分配鍵值對。 – adhithiyan
@adhithiyan它沒有工作 – MaggotSauceYumYum
你會驚訝我在我的其他活動（P15，S15）使用相同的代碼，它工作正常，我只是複製粘貼代碼在他們所有。其工作正常p15，p20，p30，但不適用於p1m，p2m，p3m，p5m和p7m – MaggotSauceYumYum
