介绍
GitHub上的一个封装：
https://github.com/belerweb/pinyin4j
pinyin4J 是一个可以将汉字转换成拼音的lib，非常实用，其
提供的 PinyinHelper 这个静态类对外提供拼音转换的服务，主要用到以下两个方法：
static public String[] toHanyuPinyinStringArray(char ch) //将char(必须为汉字单字)转化为拼音，如果ch为非汉字，返回null
static public String[] toHanyuPinyinStringArray(char ch,HanyuPinyinOutputFormat outputFormat) //可以设置输出的格式
1
static public String[] toHanyuPinyinStringArray(char ch) //将char(必须为汉字单字)转化为拼音，如果ch为非汉字，返回null
2
static public String[] toHanyuPinyinStringArray(char ch,HanyuPinyinOutputFormat outputFormat) //可以设置输出的格式
测试
将字符转为拼音数组
char c='乾';
System.out.println(Arrays.toString(PinyinHelper.toHanyuPinyinStringArray(c)));//[qian2, gan1]
System.out.println(Arrays.toString(PinyinHelper.toGwoyeuRomatzyhStringArray(c)));//[chyan, gan]
System.out.println(Arrays.toString(PinyinHelper.toMPS2PinyinStringArray(c)));//[chian2, gan1]
System.out.println(Arrays.toString(PinyinHelper.toTongyongPinyinStringArray(c)));//[cian2, gan1]
System.out.println(Arrays.toString(PinyinHelper.toWadeGilesPinyinStringArray(c)));//[ch`ien2, kan1]
System.out.println(Arrays.toString(PinyinHelper.toYalePinyinStringArray(c)));//[chyan2, gan1]x
1
char c='乾';
2
System.out.println(Arrays.toString(PinyinHelper.toHanyuPinyinStringArray(c)));//[qian2, gan1]
3
System.out.println(Arrays.toString(PinyinHelper.toGwoyeuRomatzyhStringArray(c)));//[chyan, gan]
4
System.out.println(Arrays.toString(PinyinHelper.toMPS2PinyinStringArray(c)));//[chian2, gan1]
5
System.out.println(Arrays.toString(PinyinHelper.toTongyongPinyinStringArray(c)));//[cian2, gan1]
6
System.out.println(Arrays.toString(PinyinHelper.toWadeGilesPinyinStringArray(c)));//[ch`ien2, kan1]
7
System.out.println(Arrays.toString(PinyinHelper.toYalePinyinStringArray(c)));//[chyan2, gan1]
对于 乾 和 重 的拼音转换，以上方法分别得到的结果是：
汉语拼音：[qian2, gan1]，[zhong4, chong2]
国语罗马字：[chyan, gan]，[jonq, chorng]
注音符号拼音：[chian2, gan1]，[jung4, chung2]
通用拼音：[cian2, gan1]，[jhong4, chong2]
威妥玛拼音：[ch`ien2, kan1]，[chung4, ch`ung2]
耶魯拼音：[chyan2, gan1]，[jung4, chung2]x
1
汉语拼音：[qian2, gan1]，[zhong4, chong2]
2
国语罗马字：[chyan, gan]，[jonq, chorng]
3
注音符号拼音：[chian2, gan1]，[jung4, chung2]
4
通用拼音：[cian2, gan1]，[jhong4, chong2]
5
威妥玛拼音：[ch`ien2, kan1]，[chung4, ch`ung2]
6
耶魯拼音：[chyan2, gan1]，[jung4, chung2]
拼音输出格式设置
HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
System.out.println(Arrays.toString(PinyinHelper.toHanyuPinyinStringArray(c, format)));x
1
HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
2
System.out.println(Arrays.toString(PinyinHelper.toHanyuPinyinStringArray(c, format)));
设置大小写，默认 LOWERCASE
format.setCaseType(HanyuPinyinCaseType.UPPERCASE);//大小写，默认 LOWERCASE
1
format.setCaseType(HanyuPinyinCaseType.UPPERCASE);//大小写，默认 LOWERCASE
设置音调的样式：数字WITH_TONE_NUMBER，声调符WITH_TONE_MARK，无声调。默认 WITH_TONE_NUMBER
format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);//音调的样式，默认 WITH_TONE_NUMBER
//[QIAN2, GAN1]，[QIÁN, GĀN]，[QIAN, GAN]x
1
format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);//音调的样式，默认 WITH_TONE_NUMBER
2
//[QIAN2, GAN1]，[QIÁN, GĀN]，[QIAN, GAN]
符合 V 的输出格式，使用U且带冒号WITH_U_AND_COLON，
使用U且上面带雨点WITH_U_UNICODE，
使用V符合WITH_V，默认 WITH_U_AND_COLON
format.setVCharType(HanyuPinyinVCharType.WITH_V);//符合 V 的输出格式，默认 WITH_U_AND_COLON
//[LU:, LU]，[LÜ, LU]，[LV, LU]x
1
format.setVCharType(HanyuPinyinVCharType.WITH_V);//符合 V 的输出格式，默认 WITH_U_AND_COLON
2
//[LU:, LU]，[LÜ, LU]，[LV, LU]
