排序列表时，Android的忽略大小写

问题描述

我有一个列表命名的路我正在整理我的琴弦用下面的code

I have a List named path I'm currently sorting my strings with the following code

  java.util.Collections.sort(path);

这是工作的罚款它梳理我的名单但它把第一个字母的情况下，不同的是它排序列表大写字母，然后经过这么排序列表小写字母，如果我有以下的猫狗鸟斑马它会排序它像

That is working fine it sorts my list however it treats the cases of the first letter differently that is it sorts the list with upper-case letters and then sorts the list with lower-case letters after so if I had the following cat dog Bird Zebra it would sort it like

Bird
Zebra
dog
cat

让我怎么忽略的情况下，这样的狗和猫会来的Zebra之前，但伯德之后？感谢您的帮助

so how do I ignore case so that dog and cat would come before Zebra but after Bird?Thank you for any help

推荐答案

创建一个自定义比较器类：

Create a custom comparator class:

import java.util.Comparator;

class IgnoreCaseComparator implements Comparator<String> {
  public int compare(String strA, String strB) {
    return strA.compareToIgnoreCase(strB);
  }
}

然后在你的排序：

Then on your sort:

IgnoreCaseComparator icc = new IgnoreCaseComparator();

java.util.Collections.sort(path,icc);
