使用本地化对字符串列表进行排序 [英] Sort List of Strings with Localization

问题描述

我想根据用户区域设置在字符串列表下方进行排序

I want to sort below List of strings as per user locale

List<String> words = Arrays.asList(
      "Äbc", "äbc", "Àbc", "àbc", "Abc", "abc", "ABC"
    );

对于不同的用户语言环境，排序输出应该根据语言环境不同.

For different user locale sort output should be different as per there locale.

如何根据用户区域设置对上面的列表进行排序?

How to sort above list as per user locale ?

我试过了

Collections.sort(words , String.CASE_INSENSITIVE_ORDER);

但这不适用于本地化，那么如何将 locale 参数传递给 Collections.sort() 或者还有其他有效的方法吗?

But this is not working for localization, so how to pass locale parameter to Collections.sort() or is there any other efficient way ?

推荐答案

您可以将排序与自定义比较器一起使用.请参阅整理器界面

You can use a sort with a custom Comparator. See the Collator interface

Collator coll = Collator.getInstance(locale);
coll.setStrength(Collator.PRIMARY);
Collections.sort(words, coll);

collat​​or 是一个比较器，可以直接传递给 Collections.sort(...) 方法.

The collator is a comparator and can be passed directly to the Collections.sort(...) method.
