This is not possible. Sets are unordered collections.

blocks|key|216127|text|您可以用数字作为字符串的前缀，例如00application、01bluetooth、02data，按照您想要取出它们的顺序。将从getStringSet返回的Set<String>放入Array<Set>中并对其进行排序。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|216128|Set<String>+set+=+prefs.getStringSet(key,+new+HashSet<String>());

You can prefix your strings by numbers, for instance <code>00application</code>, <code>01bluetooth</code>, <code>02data</code>, in the order you want to get them out. Put the <code>Set&lt;String&gt;</code> returned from <code>getStringSet</code> in an <code>Array&lt;Set&gt;</code> and sort it.

<pre><code>Set&lt;String&gt; set = prefs.getStringSet(key, new HashSet&lt;String&gt;());
Array&lt;String&gt; a = set.toArray();
java.util.Arrays.sort(a);
</code></pre>

You can save a list of string as a single string with a delimiter.
For example this is your array:

<pre><code>["Italy", "France", "Spain", "Japan", "United States"]
</code></pre>

You can save it as:

<pre><code>"Italy;France;Spain;Japan;United States"
</code></pre>

In code:

<pre><code>SharedPreferences sharedPref = mContext.getSharedPreferences(PREF_KEY, Context.MODE_PRIVATE);
Editor editor = sharedPref.edit();

// countries is your List
String countriesString = TextUtils.join(";", countries);
editor.putString("countries", countriesString);
editor.apply();
</code></pre>

To retrieve your data:

<pre><code>final String countriesString = sharedPref.getString("countries", "");
List&lt;String&gt; countries = new ArrayList&lt;&gt;();
if (!countriesString.isEmpty()){
 countries = new ArrayList&lt;&gt;(Arrays.asList(countriesString.split(";")));
}
</code></pre>

This works for Kotlin, replace the | character with whatever character is guaranteed not to be within your Strings.

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

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

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

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

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 ?

android SharedPreferences putStringSet order/sort

Kotlin

我尝试保存/恢复一组字符串，除了一件事之外，所有操作都正常。当我创建我的字符串时，我把：Set<String> set = new HashSet<String>();for(int i=0; i<toggles.size();i++){ set.add(toggles.get(i).serialise()); ...
