Android 共享首选项不适用于int变量
我试图使用共享首选项来存储整数值，但当应用程序处于关闭或旋转状态时，它会再次启动为零。 我想保存该变量值，即使我的应用程序被终止或关闭 我想保存名为alhamdulilahweek的变量，这是我的代码Android 共享首选项不适用于int变量,android,sharedpreferences,Android,Sharedpreferences,我试图使用共享首选项来存储整数值，但当应用程序处于关闭或旋转状态时，它会再次启动为零。 我想保存该变量值，即使我的应用程序被终止或关闭 我想保存名为alhamdulilahweek的变量，这是我的代码 public class FragTasbeeh extends Fragment { public static final String[] items={"Alhamdulilah","SubhanAllah","AllahuAkbar"}; ImageView ivI
