android SharedPreferences putStringSet 顺序/排序

android SharedPreferences putStringSet order/sort(android SharedPreferences putStringSet 顺序/排序)

问题描述

我尝试保存/恢复一组字符串，除一件事外，一切正常.当我创建我的字符串时，我放了:

I try to save/restore a set of string and all is working except one thing. When i create my strings i put :

Set<String> set = new HashSet<String>();
for(int i=0; i<toggles.size();i++){
   set.add(toggles.get(i).serialise());                 
}

顺序例如是蓝牙"应用程序"数据".当我回来的时候:

Order is for example "blutooth" "application" "data". When i get back set :

Set<String> set = prefs.getStringSet(key, new HashSet<String>());
for (String toggle : set){
    Toggle t = new Toggle();
    t.deserialize(toggle);
    toggles.add(t); 
}

我得到应用程序"蓝牙"数据"，它们是按名称排序的，我不想要这个.我想获得与我保存的相同的订单.任何人都可以帮助我吗?

I get "application" "bluetooth" "data" they are sort by name and i don't want this. I want to get same order i have save. Anyone can help me ?

推荐答案

这是不可能的.集合是无序的集合.

This is not possible. Sets are unordered collections.
