Bean对象：

public class NameBean {private String name;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getNameFirstChar() {return getFirstChar(name);}// 获得字符串的首字母 首字符 转汉语拼音public String getFirstChar(String value) {// 首字符char firstChar = value.charAt(0);// 首字母分类String first = null;// 是否是非汉字String[] print = PinyinHelper.toHanyuPinyinStringArray(firstChar);if (print == null) {// 将小写字母改成大写if ((firstChar >= 97 && firstChar <= 122)) {firstChar -= 32;}if (firstChar >= 65 && firstChar <= 90) {first = String.valueOf((char) firstChar);} else {// 认为首字符为数字或者特殊字符first = "#";}} else {// 如果是中文 分类大写字母first = String.valueOf((char) (print[0].charAt(0) - 32));}if (first == null) {first = "?";}return first;}}

实现比较的接口：

public class MyComparator implements Comparator<NameBean> {String ostr1;String ostr2;@Overridepublic int compare(NameBean bean1, NameBean bean2) {ostr1 = bean1.getNameFirstChar();ostr2 = bean2.getNameFirstChar();for (int i = 0; i < ostr1.length() && i < ostr2.length(); i++) {int codePoint1 = ostr1.charAt(i);int codePoint2 = ostr2.charAt(i);if (Character.isSupplementaryCodePoint(codePoint1)|| Character.isSupplementaryCodePoint(codePoint2)) {i++;}if (codePoint1 != codePoint2) {// 拼音字符if (Character.isSupplementaryCodePoint(codePoint1)|| Character.isSupplementaryCodePoint(codePoint2)) {return codePoint1 - codePoint2;}String pinyin1 = pinyin((char) codePoint1);String pinyin2 = pinyin((char) codePoint2);if (pinyin1 != null && pinyin2 != null) { // 两个字符都是汉字if (!pinyin1.equals(pinyin2)) {return pinyin1.compareTo(pinyin2);}} else {return codePoint1 - codePoint2;}}}return ostr1.length() - ostr2.length();}// 获得汉字拼音的首字符private String pinyin(char c) {String[] pinyins = PinyinHelper.toHanyuPinyinStringArray(c);if (pinyins == null) {return null;}return pinyins[0];}}

测试：

public class TestMain {public static void main(String[] args) {String[] str = { "计算机", "网络", "回收站", "Fire", "驱动精灵", "百度", "白色", "无恐","lxz", "A酱", "芙兰", "鱼鱼", "妹妹", "你好", "林小姐", "联盟", "L","xdsfsdggsdsf", "星星", "靴刀誓死", "Java", "倒塌", "黑人", "a妹", "aYa","Admin", "ali", "阿san", };List<NameBean> arrList = new ArrayList<NameBean>();for (String s : str) {NameBean bean = new NameBean();bean.setName(s);arrList.add(bean);}MyComparator compare = new MyComparator();Collections.sort(arrList, compare);for (NameBean b : arrList) {System.out.println(b.getNameFirstChar() + ";" + b.getName());}}}
