Android 按照字母排序汉字,可用于通讯录_安卓 compare 怎么实现同字母汉字在前字母在后

比较类,资源类

public class CompareData implements Comparable<CompareData> {
 
    private String str;
 
    public CompareData(String str) {
        this.str = str;
    }
 
    @Override
    public int compareTo(CompareData o) {
 
        char strFirstChar = getStrFirstChar(str);
        char strFirstCharO = getStrFirstChar(o.str);
        if (strFirstChar < strFirstCharO) {
            return -1;
        }
        if (strFirstChar > strFirstCharO) {
            return 1;
        }
        return 0;
    }
 
    private char getStrFirstChar(String str) {
        String pinyinFirstLetter = PinyinUtils.getPinyinFirstLetter(str);
        char c = pinyinFirstLetter.charAt(0);
        return c;
    }
 
    public String getStr() {
        return str;
    }
 
    public void setStr(String str) {
        this.str = str;
    }
}

AndroidUtilCode 的 pinyinutil

        List<CompareData> listDatas = new ArrayList<CompareData>() {{
            add(new CompareData("张三"));
            add(new CompareData("李四"));
            add(new CompareData("王麻子"));
            add(new CompareData("鬼脚七"));
            add(new CompareData("黄飞鸿"));
            add(new CompareData("小白兔"));
            add(new CompareData("白又白"));
            add(new CompareData("臭傻吊"));
        }};
 
        Collections.sort(listDatas);
 
 
        for (int i = 0; i < listDatas.size(); i++) {
            CompareData compareData = listDatas.get(i);
            System.out.println(compareData.getStr() + "");
        }

效果:

拼音带音标的尝试:

    compile 'com.github.open-android:pinyin4j:2.5.0'

 //-------------------指定格式转换----------------------------
        HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
 
        // UPPERCASE：大写  (ZHONG)
        // LOWERCASE：小写  (zhong)
        format.setCaseType(HanyuPinyinCaseType.LOWERCASE);//输出小写
 
        // WITHOUT_TONE：无音标  (zhong)
        // WITH_TONE_NUMBER：1-4数字表示音标  (zhong4)
        // WITH_TONE_MARK：直接用音标符（必须WITH_U_UNICODE否则异常）  (zhòng)
        format.setToneType(HanyuPinyinToneType.WITH_TONE_MARK);
 
        // WITH_V：用v表示ü  (nv)
        // WITH_U_AND_COLON：用"u:"表示ü  (nu:)
        // WITH_U_UNICODE：直接用ü (nü)
        format.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE);
 
        String[] hao = new String[0];
        try {
            hao = PinyinHelper.toHanyuPinyinStringArray('你', format);
        } catch (BadHanyuPinyinOutputFormatCombination badHanyuPinyinOutputFormatCombination) {
            badHanyuPinyinOutputFormatCombination.printStackTrace();
        }
 
        for (String s : hao) {
            System.out.println(s);
        }

如果是多音字那么就会有俩个,

可以结合我上面的比较类直接实现多功能
