排序列表与语言环境

Question

我想排序ArrayList<Object>。 （字母排序）

我使用下列代码进行排序：

Collections.sort(arr_items, new Comparator<Helper>() { 


     @Override 
     public int compare(Helper one, Helper two) { 
      // TODO Auto-generated method stub 

      return one.getTitle().compareTo(two.getTitle()); 
     } 

    }); 

现在如果我想设置一个 Locale它我该怎么办

？

Locale arrabic= new Locale("ar"); 
    Collator arrabicCollator = Collator.getInstance(arrabic); 

Answer 1

你Comparator需要使用Collator这样的：

Locale arrabic= new Locale("ar"); 
final Collator arrabicCollator = Collator.getInstance(arrabic); 
Collections.sort(arr_items, new Comparator<Helper>() { 

    @Override 
    public int compare(Helper one, Helper two) { 
     return arrabicCollator.compare(one.getTitle(), two.getTitle()); 
    } 

}); 

的排序。
