学习笔记之——封装关于字符串中的中文转拼音、获得汉语拼音首字母工具类

         由于项目需求，用到字符串汉字转拼音的功能，此处贴上已经封装好的工具类代码，可以直接使用的

public class PinyinUtils {
/**
 * 获得汉语拼音首字母
 * 
 * @return
 */
public static String getAlpha(String chines) {
String pinyinName = "";
char[] nameChar = chines.toCharArray();
HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
defaultFormat.setCaseType(HanyuPinyinCaseType.UPPERCASE);
defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
for (int i = 0; i < nameChar.length; i++) {
if (nameChar[i] > 128) {
try {
pinyinName += PinyinHelper.toHanyuPinyinStringArray(
nameChar[i], defaultFormat)[0].charAt(0);
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
} else {
pinyinName += nameChar[i];
}
}
return pinyinName;
}

/**
 * 将字符串中的中文转化为拼音,其他字符不变
 * 
 * @param inputString
 * @return
 */
public static String getPingYin(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 (java.lang.Character.toString(input[i]).matches(
"[\\u4E00-\\u9FA5]+")) {
String[] temp = PinyinHelper.toHanyuPinyinStringArray(
input[i], format);
output += temp[0];
} else
output += java.lang.Character.toString(input[i]);
}
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
return output;
}

/**
 * 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 = "";
