Java中如何将中文转换为英文String
_夜渐凉

收藏 5 在JAVA 编程中我们经常免不了需要对中文排序，而往往我们排序的依据就是中文的首字母，当然无论依据什么排序，我们都需要将中文转换成为String
首先，我们要调用一个库 pinyin4j-2.5.0.jar
下载地址：//sourceforge.net/projects/pinyin4j/
下载解压，里面有个pinyin4j-2.5.0.jar，使用这个库即可。
其次，使用这个库，使用的方法很简单，需要注意以下几点：
// UPPERCASE：大写 (ZHONG)
// LOWERCASE：小写 (zhong)
format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
// WITHOUT_TONE：无音标 (zhong)
// WITH_TONE_NUMBER：1-4数字表示英标 (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); 更加直接的说，将中文转换成为String 主要是使用下面的这个接口：
PinyinHelper.toHanyuPinyinStringArray(input[i], format);
这个接口有个容错判断 如果input 如果传入的不是汉字，就不能转换成拼音，
那么直接返回null，所以需要用正则表达式判断是否是中文 Character.toString(input[i]).matches("[\\u4E00-\\u9FA5]+")
更加具体的内容请看下面的完整代码
public static String getPinYin(String inputString) {
HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
format.setVCharType(HanyuPinyinVCharType.WITH_V);
char[] input = inputString.trim().toCharArray();
String output = "";
try {
for (int i = 0; i < input.length; i++) {
if (Character.toString(input[i]).matches("[\\u4E00-\\u9FA5]+")) { //判断字符是否是中文
//toHanyuPinyinStringArray 如果传入的不是汉字，就不能转换成拼音，那么直接返回null
//由于中文有很多是多音字，所以这些字会有多个String，在这里我们默认的选择第一个作为pinyin
String[] temp = PinyinHelper.toHanyuPinyinStringArray(input[i], format);
output += temp[0];
} else {
output += Character.toString(input[i]);
}
}
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
// Log.v(TAG, "BadHanyuPinyinOutputFormatCombination");
}
return output;
}
/**
* 取出拼音中第一个字母,一般第一个字母的使用时比较常见的
* @param chines
* @return
*/
public static String converterToFirstSpell(String chines) {
String pinyinName = "";
char[] nameChar = chines.toCharArray();
HanyuPinyinOutputFormat defaulFormat = new HanyuPinyinOutputFormat();
defaulFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
defaulFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
defaulFormat.setVCharType(HanyuPinyinVCharType.WITH_V);
for (int i = 0; i < nameChar.length; i++) {
if (nameChar[i] > 128) {
try {
pinyinName += PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaulFormat)[0].charAt(0);
} catch (BadHanyuPinyinOutputFormatCombination ex) {
ex.printStackTrace();
}
} else {
pinyinName += nameChar[i];
}
}
return pinyinName;
}
