汉字排序

  public class CollatorComparator implements Comparator {
				
				Collator collator = Collator.getInstance(java.util.Locale.CHINA);
				public int compare(Object element1, Object element2) {

					CollationKey key1 = collator.getCollationKey(((InvitePeopleConnect) element1).getPeopleName());
					CollationKey key2 = collator.getCollationKey(((InvitePeopleConnect) element2).getPeopleName());
					
					
					return key1.compareTo(key2);
				}
			}

 Collections.sort(ConPeopleList, new CollatorComparator()); 调用

 

private ArrayList<InvitePeopleConnect> ConPeopleList=new ArrayList<InvitePeopleConnect>();

 

这里只是简单的不使用外部jar的，排序的结果是先数字 然后字母  然后中文  字母喝中文分别按照字母排序

 

如果调用pinyin4j。jar

  public class CollatorComparator implements Comparator {
				//Collator collator = Collator.getInstance(java.util.Locale.CHINA);
				Collator collator = Collator.getInstance(java.util.Locale.CHINA);
				public int compare(Object element1, Object element2) {

					//CollationKey key1 = collator.getCollationKey(((InvitePeopleConnect) element1).getPeopleName());
					//CollationKey key2 = collator.getCollationKey(((InvitePeopleConnect) element2).getPeopleName());
					
					CollationKey key1 = collator.getCollationKey(getAllFirstLetter(((InvitePeopleConnect) element1).getPeopleName()));
					CollationKey key2 = collator.getCollationKey(getAllFirstLetter(((InvitePeopleConnect) element2).getPeopleName()));
					return key1.compareTo(key2);
				}
			}
		  
		    public String getAllFirstLetter(String str) { 
		        String convert = ""; 
		        for (int j = 0; j < str.length(); j++) { 
		            char word = str.charAt(j); 
		            String[] pinyinArray = PinyinHelper.toHanyuPinyinStringArray(word); 
		            if (pinyinArray != null) { 
		                convert += pinyinArray[0].charAt(0); 
		            }else { 
		                convert += word; 
		            } 
		        } 
		        return convert; 
		    }
