Android使用SharedPreferences存储XML文件的实现方法

@Override
public void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  //初始化DBManager
  mgr = new ProductDBManager(getActivity());
  //实例化
  SharedPreferences sp = getActivity().getSharedPreferences("SP", 0);
  //存储数据
  Editor sharedata = sp.edit();
  sharedata.putString("name","she缓存数据");
  sharedata.commit();
  //读取数据,如果数据为空，则返回第二个参数的默认数据;
  String str = sp.getString("name", "none");
}
