Android 汉语转拼音
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。

}
private void addToken(
final StringBuilder sb, final ArrayList<Token> tokens, final int tokenType) {
String str = sb.toString();
tokens.add(new Token(tokenType, str, str));
sb.setLength(0);
}
}
使用方法：
转换汉字：我爱我中华China
package com.maidou.utils;
import android.app.Activity;
/**
*
******************************************************
* @author LK
******************************************************
*/
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String hanzi = "我爱我中华China";
Log.i("info", "汉字：" + hanzi);
String pin = getPinYin(hanzi);
Log.i("info", "拼音：" + pin);
}
/**
* 汉字转换拼音，字母原样返回，都转换为小写
*
* @param input
* @return
*/
public static String getPinYin(String input) {
ArrayList<HanziToPinyin.Token> tokens = HanziToPinyin.getInstance().get(input);
StringBuilder sb = new StringBuilder();
if (tokens != null && tokens.size() > 0) {
for (HanziToPinyin.Token token : tokens) {
if (token.type == HanziToPinyin.Token.PINYIN) {
sb.append(token.target);
} else {
sb.append(token.source);
}
}
}
return sb.toString().toLowerCase();
}
}
输出结果：
// 输出结果： // 汉字：我爱我中华China // 拼音：woaiwozhonghuachina
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。
