public class PinYinKit {
    /**

     */
    public static String getPingYin(String chineseStr) throws BadHanyuPinyinOutputFormatCombination {
        String zhongWenPinYin = "";
        char[] chars = chineseStr.toCharArray();

        for (int i = 0; i < chars.length; i++) {
            String[] pinYin = PinyinHelper.toHanyuPinyinStringArray(chars[i], getDefaultOutputFormat());
            if (pinYin != null)
                zhongWenPinYin += pinYin[0];
            else
                zhongWenPinYin += chars[i];
        }
        return zhongWenPinYin;
    }

    private static HanyuPinyinOutputFormat getDefaultOutputFormat() {
        HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
        format.setCaseType(HanyuPinyinCaseType.UPPERCASE);
        format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
        format.setVCharType(HanyuPinyinVCharType.WITH_U_AND_COLON);
        return format;
    }
}

在java中，如果要对集合对象或数组对象进行排序，需要实现Comparator接口以达到我们想要的目标。

package com.zhishucaipei.ksb.utils;

import com.zhishucaipei.ksb.bean.LinkManInfoVO;

import java.util.Comparator;


public class PinyinComparator implements Comparator<LinkManInfoVO> {

    public int compare(LinkManInfoVO o1, LinkManInfoVO o2) {
        if (o1.getSortLetters().equals("@") || o2.getSortLetters().equals("#"))
            return -1;
        else if (o1.getSortLetters().equals("#") || o2.getSortLetters().equals("@"))
            return 1;
        else
            return o1.getSortLetters().compareTo(o2.getSortLetters());
    }

}

实际使用的方式：

RequestParams params = new RequestParams(UrlConstants.getLinkManAll);
params.addBodyParameter("accessToken", user.getData().getAccessToken());
x.http().post(params, new Callback.CommonCallback<String>() {

    @Override
    public void onSuccess(String result) {
        try {
            JSONObject object = new JSONObject(result);
            Gson gson = new Gson();
            LinkManBean linkManBean = gson.fromJson(object.toString(), LinkManBean.class);
            LinkManInfoData = linkManBean.getData();
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onError(Throwable ex, boolean isOnCallback) {

    }

    @Override
    public void onCancelled(CancelledException cex) {

    }

    @Override
    public void onFinished() {
        // sort by a-z
        BaseApplication.setLinkManInfoList(LinkManInfoData);
        try {
            sortModelList = filledData(LinkManInfoData);
        } catch (BadHanyuPinyinOutputFormatCombination badHanyuPinyinOutputFormatCombination) {
            badHanyuPinyinOutputFormatCombination.printStackTrace();
        }
        Collections.sort(sortModelList, comparator);
        adapter = new SortAdapter(getContext(), sortModelList);
        sortListView.setAdapter(adapter);
    }
});
