Pinyin4j是一个流行的Java库，支持中文字符和拼音之间的转换。拼音输出格式可以定制。
代码实现如下：
1.带声调的方法
/**
* 汉字转换位汉语拼音，英文字符不变 带声调的方法
* @param chines 汉字
* @return 拼音
*/
public static String converterToSpellWithTONE(String chines) {
String pinyinName = "";
char[] nameChar = chines.toCharArray();
HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
defaultFormat.setToneType(HanyuPinyinToneType.WITH_TONE_NUMBER);
defaultFormat.setVCharType(HanyuPinyinVCharType.WITH_V);
for (int i = 0; i < nameChar.length; i++) {
if (nameChar[i] > 128) {
try {
if (PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaultFormat) != null
&& PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaultFormat).length > 0) {
pinyinName += PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaultFormat)[0];
}
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
} else {
pinyinName += nameChar[i];
}
}
return pinyinName;
}
2.不带声调的方法
/**
* 汉字转换位汉语拼音，英文字符不变
* @param chines 汉字
* @return 拼音
*/
public static String converterToSpell(String chines) {
String pinyinName = "";
char[] nameChar = chines.toCharArray();
HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
defaultFormat.setVCharType(HanyuPinyinVCharType.WITH_V);
for (int i = 0; i < nameChar.length; i++) {
if (nameChar[i] > 128) {
try {
if (PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaultFormat) != null
&& PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaultFormat).length > 0) {
pinyinName += PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaultFormat)[0];
}
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
} else {
pinyinName += nameChar[i];
}
}
return pinyinName;
}
3.
/**
* 汉字转换位汉语拼音首字母，英文字符不变
* @param chines 汉字
* @return 拼音
*/
public static String converterToFirstSpell(String chines) {
String pinyinName = "";
char[] nameChar = chines.toCharArray();
HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
defaultFormat.setVCharType(HanyuPinyinVCharType.WITH_V);
for (int i = 0; i < nameChar.length; i++) {
if (nameChar[i] > 128) {
try {
if (PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaultFormat) != null
&& PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaultFormat).length > 0) {
pinyinName += PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaultFormat)[0].charAt(0);
}
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
} else {
pinyinName += nameChar[i];
}
}
return pinyinName;
}
