Android 汉语转拼音

11年前
有很多时候我们需要将汉字转换为拼音，例如手机中的联系人排序、在12306买车票时输入SZ\shenzhen就会提示深圳。
Android提供了汉字转拼音的类HanziToPinyin.java，据说这个类是在联系人app下的。具体目录是packages/providers/ContactsProvider /src/com/android/providers/contacts的HanziToPinyin.java文件。
不过俺是新手没有找到这个类，不过网上有不少大神都把源码贴出来了，我也借鉴一下。

也有人说使用 Java开源类库pinyin4j。不过貌似不能解决多音字。
自我感觉还是使用Android官方的好点，不过都可以解决问题，随自己选择了。
如果是使用联系人排序，在转换成拼音之后，截取首字母进行比较排序。
