添加的pinyin4j包，这边有他的下载地址http://pan.baidu.com/s/1mgnMdsc
public class Change {
private String[] pinyin = null; HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat(); public String getCharacterPinyin(char c) { try { pinyin = PinyinHelper.toHanyuPinyinStringArray(c, format); } catch (BadHanyuPinyinOutputFormatCombination e) { // TODO Auto-generated catch block e.printStackTrace(); } if (pinyin == null) { return null; } return pinyin[0]; } public String getStringPinYin(String str) { format.setCaseType(HanyuPinyinCaseType.LOWERCASE); format.setToneType(HanyuPinyinToneType.WITH_TONE_MARK); format.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE); StringBuilder sb = new StringBuilder(); String tempPinyin = null; for (int i = 0; i < str.length(); i++) { tempPinyin = getCharacterPinyin(str.charAt(i)); if (tempPinyin == null) { sb.append(str.charAt(i)); } else { sb.append(tempPinyin); } } return sb.toString(); } }
下面是基础知识，我转载的
使用pinyin4j - 小米米儿小的个人空间 - 开源中国社区
Pinyin4j就是为了解决类似这样的问题的。它是sourceforge.net上的一个开源项目，功能非常强大：
+ 支持同一汉字有多个发音
+ 还支持拼音的格式化输出，比如第几声之类的，
基本用法
通常情况下，只需要用到其中的PinyinHelper类中的静态方法toHanyuPinyinStringArray就可以了
| 1 2 3 4 | String[] pinyinArray =PinyinHelper.toHanyuPinyinStringArray('单'); for(inti = 0; i < pinyinArray.length; ++i){ System.out.println(pinyinArray[i]); } |
| 1 2 3 4 5 6 7 8 9 10 11 12 | HanyuPinyinOutputFormat format= newHanyuPinyinOutputFormat(); format.setToneType(HanyuPinyinToneType.WITH_TONE_MARK); format.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE); String[] pinyinArray = null; try{ pinyinArray = PinyinHelper.toHanyuPinyinStringArray('黄', format); }catch(BadHanyuPinyinOutputFormatCombination e){ e.printStackTrace(); } for(inti = 0; i < pinyinArray.length; ++i){ System.out.println(pinyinArray[i]); } |
