谢邀，，，
将数据保存至SharedPreferences:
SharedPreferences preferences=getSharedPreferences("user",Context.MODE_PRIVATE);
Editor editor=preferences.edit();
String name="xixi";
String age="22";
editor.putString("name", name);
editor.putString("age", age);
editor.commit();
从SharedPreferences获取数据:
SharedPreferences preferences=getSharedPreferences("user", Context.MODE_PRIVATE);
String name=preferences.getString("name", "defaultname");
String age=preferences.getString("age", "0");
