android 本地存储数据

 String PREFS_NAME = "lmn.com"; String ItemUser = "username"; String ItemPass = "password"; String ItemCheck = "check";

 

一 存储

   SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);    SharedPreferences.Editor editor = settings.edit();    editor.putBoolean(ItemCheck, checkBox.isChecked());    editor.putString(ItemUser, username);    editor.putString(ItemPass, password);    editor.commit();

二 读取

 SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);  boolean silent = settings.getBoolean(ItemCheck, false);  String username = settings.getString(ItemUser, "");  String password = settings.getString(ItemPass, "");
