pinyin4j的简单使用（中文字符和拼音之间的转换）

	private HanyuPinyinOutputFormat mOutputFormat = null;
		mOutputFormat = new HanyuPinyinOutputFormat();
		mOutputFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);//设置大小写
		mOutputFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);//设置音调格式
		

	public String parserWordsToPinyin(String words) {
		if (words == null || words.trim().length() == 0) {
			return "###";
		}
		String py = "", temp = "";
		String[] t = null;
		for (int i = 0; i < words.length(); i++) {
			char c = words.charAt(i);
			if (((int) c) <= 128) {    //ascii 码小于128的都是字符数字之类
				py += c;
			} else {
				try {
					t = PinyinHelper.toHanyuPinyinStringArray(c, mOutputFormat);
					if (t == null) {
						py += c;
					} else {
						temp = t[0];
//						py += temp + (i == words.length() -1 ? "" : "_");
						py += temp;
					}
				} catch (BadHanyuPinyinOutputFormatCombination e) {
					e.printStackTrace();
				}
			}
