中文姓名排序

在android中，我们经常要用到HashMap，经常用list存放HashMap，我们对List中的元素进行排序的时候，就要用到构造器了，下面具体用列子说说：

假如在main方法中有：

 public List<HashMap<String, Object>> listitem;       listitem.add(new HashMap("name","one"));       listitem.add(new HashMap("name","张三"));       listitem.add(new HashMap("name","李四"));       listitem.add(new HashMap("name","王五"));       listitem.add(new HashMap("name","two"));             Comparent comparent = new Comparent();       Collections.sort(listitem, comparent);

?

其中在Comparent.java文件中定义方法如下：

import java.text.Collator;import java.util.Comparator;import java.util.HashMap;import java.util.Locale;public class Comparent implements  Comparator<Object> { @SuppressWarnings("unchecked") @Override public int compare(Object arg0, Object arg1) {  HashMap<String, Object> name1 = (HashMap<String, Object>)arg0;  HashMap<String, Object> name2 = (HashMap<String, Object>)arg1;  Collator ca = Collator.getInstance(Locale.CHINA);  int flags = 0;  if (ca.compare((String) name1.get("name"), (String)name2.get("name")) < 0) {   flags = -1;  }  else if(ca.compare((String) name1.get("name"), (String)name2.get("name")) > 0) {   flags = 1;  }  else {   flags = 0;  }  return flags; }}
