public class PinyinTool {
  
  public static void main(String[] args) throws BadHanyuPinyinOutputFormatCombination {
    //设置拼音输出格式
    HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
    //小写字母
    format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
    //标注声调,必须有下面v的设置,不然会抛出异常,不设置的话拼音输出为 “我：wo3”
    format.setToneType(HanyuPinyinToneType.WITH_TONE_MARK);
    //使用v
    format.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE);

    String chinese = "我还是拼音字符串";
    int lenght = chinese.length();
    for (int i = 0; i < lenght; ++i) {
      //判断是否为汉字
      if (java.lang.Character.toString(chinese.charAt(i)).matches("[\\u4E00-\\u9FA5]+")) {
        //转为字符串，多音字有多个
        String[] s = PinyinHelper.toHanyuPinyinStringArray(chinese.charAt(i), format);
        //多音字逐个输出
        for (String ss : s) System.out.print(ss + " ");
        System.out.println();
      }
    }
  }
