推荐这篇日记的豆列（转）汉字转拼音HanziToPinyin
来源：博客园

Android系统本身自带有有将汉字转化为英文拼音的类和方法。具体的类就是HanziToPinyin.java。Android系统自身实现的通讯录中就使用了HanziToPinyin.java对中文通讯录做分组整理。通过HanziToPinyin.java可以将汉字转化为拼音输出，在一些应用中非常必须，比如联系人的分组，假设一个人通讯录中存有若干姓张（ZHANG）的联系人，那么所有姓张的联系人按理都应该分组在“Z”组下。又比如微信、QQ等等此类社交类APP，凡是涉及到联系人、好友分组排序的应用场景，则均需要将汉字转化为拼音然后依据首字母排序归类。HanziToPinyin.java不是一个公开的类，只是谷歌官方内部在实现Android通讯录中私有使用的一个类，我们不能够直接像使用普通Android SDK API一样使用，但这没关系，我们完全可以将这个类文件拷贝出来，放到我们自己的项目中，直接使用。HanziToPinyin.java的代码文件，谷歌官方的通讯录APP下：
packages/providers/ContactsProvider /src/com/android/providers/contacts/HanziToPinyin.java
网上也有这个HanziToPinyin.java类文件的项目地址。但是，直接使用这个 类不能正常工作，错误原因是：
"There is no Chinese collator, HanziToPinyin is disabled"
发生这一错误的代码块是在HanziToPinyin.java的方法：public static HanziToPinyin getInstance();具体原因是这个方法在一些非原生定制的Android系统中，对中文Locale的定义规则不同，导致原代码文件中的locale[i].equals(Locale.CHINA)返回false，不能识别，致使以后的代码全部失去功效。
对此问题的修复（解决方案）
我改进了判断条件，增加一些代码：final Locale chinaAddition = new Locale("zh");将此chinaAddition作为辅助条件也加入到条件判断中，
1 if ( locale[i].equals(Locale.CHINA) ||
locale[i].equals(chinaAddition) ){
2 …
3 }
下面是我改进后的getInstance()方法全部代码：
1 public static HanziToPinyin getInstance() {
2
synchronized (HanziToPinyin.class) {
3
if (sInstance != null) {
4
return sI
5
// Check if zh_CN collation data is available
7
final Locale locale[] = Collator.getAvailableLocales();
8
9
// 增加的代码，增强。
10
final Locale chinaAddition = new Locale("zh");
11
12
for (int i = 0; i & locale. i++) {
13
if (locale[i].equals(Locale.CHINA)
14
|| locale[i].equals(chinaAddition)) {
15
// Do self validation just once.
16
if (DEBUG) {
17
Log.d(TAG, "Self validation. Result: "
18
+ doSelfValidation());
19
sInstance = new HanziToPinyin(true);
21
return sI
22
Log.w(TAG,
25
"There is no Chinese collator, HanziToPinyin is disabled");
26
sInstance = new HanziToPinyin(false);
27
return sI
28
}
经由改进增强，HanziToPinyin.java的全部源代码如下（代码可以复制到自己的项目中直接使用）：

HanziToPinyin.java
写一个MainActivity.java测试汉字转化为汉语拼音输出的效果：
1 package zhangphil.
2
3 import java.util.ArrayL
4
5 import zhangphil.hanyupinyin.HanziToPinyin.T
6 import android.app.A
7 import android.os.B
8
9 public class MainActivity extends Activity {
10
11
@Override
12
protected void onCreate(Bundle savedInstanceState) {
13
super.onCreate(savedInstanceState);
14
15
String s = "安卓";
16
System.out.println("汉字转拼音输出: " + getPinYin(s));
17
}
18
19
// 输入汉字返回拼音的通用方法函数。
20
public static String getPinYin(String hanzi) {
21
ArrayList&Token& tokens = HanziToPinyin.getInstance().get(hanzi);
22
StringBuilder sb = new StringBuilder();
23
if (tokens != null && tokens.size() & 0) {
24
for (Token token : tokens) {
25
if (Token.PINYIN == token.type) {
26
sb.append(token.target);
27
} else {
28
sb.append(token.source);
29
}
32
33
return sb.toString().toUpperCase();
34
}
35 }
结果输出如图：
