Android系統本身自帶有有將漢字轉化為英文拼音的類和方法。具體的類就是HanziToPinyin.java。Android系統自身實現的通訊錄中就使用了HanziToPinyin.java對中文通訊錄做分組整理。通過HanziToPinyin.java可以將漢字轉化為拼音輸出，在一些應用中非常必須，比如聯系人的分組，假設一個人通訊錄中存有若干姓張（ZHANG）的聯系人，那麼所有姓張的聯系人按理都應該分組在“Z”組下。又比如微信、QQ等等此類社交類APP，凡是涉及到聯系人、好友分組排序的應用場景，則均需要將漢字轉化為拼音然後依據首字母排序歸類。
HanziToPinyin.java不是一個公開的類，只是谷歌官方內部在實現Android通訊錄中私有使用的一個類，我們不能夠直接像使用普通Android SDK API一樣使用，但這沒關系，我們完全可以將這個類文件拷貝出來，放到我們自己的項目中，直接使用。
HanziToPinyin.java的代碼文件，谷歌官方的通訊錄APP下：

packages/providers/ContactsProvider /src/com/android/providers/contacts/HanziToPinyin.java

網上也有這個HanziToPinyin.java類文件的項目地址。但是，直接使用這個 類不能正常工作，錯誤原因是：

"There is no Chinese collator, HanziToPinyin is disabled"

發生這一錯誤的代碼塊是在HanziToPinyin.java的方法：
public static HanziToPinyin getInstance();
具體原因是這個方法在一些非原生定制的Android系統中，對中文Locale的定義規則不同，導致原代碼文件中的locale[i].equals(Locale.CHINA)返回false，不能識別，致使以後的代碼全部失去功效。

對此問題的修復（解決方案）

我改進了判斷條件，增加一些代碼：
final Locale chinaAddition = new Locale("zh");
將此chinaAddition作為輔助條件也加入到條件判斷中，

1 if ( locale[i].equals(Locale.CHINA) ||  locale[i].equals(chinaAddition) ){
2 …
3 }

下面是我改進後的getInstance()方法全部代碼：

 1 public static HanziToPinyin getInstance() {
 2         synchronized (HanziToPinyin.class) {
 3             if (sInstance != null) {
 4                 return sInstance;
 5             }
 6             // Check if zh_CN collation data is available
 7             final Locale locale[] = Collator.getAvailableLocales();
 8 
 9             // 增加的代碼，增強。
10             final Locale chinaAddition = new Locale("zh");
11 
12             for (int i = 0; i < locale.length; 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                     }
20                     sInstance = new HanziToPinyin(true);
21                     return sInstance;
22                 }
23             }
24             Log.w(TAG,
25                     "There is no Chinese collator, HanziToPinyin is disabled");
26             sInstance = new HanziToPinyin(false);
27             return sInstance;
28         }
29     }

經由改進增強，HanziToPinyin.java的全部源代碼如下（代碼可以復制到自己的項目中直接使用）：

寫一個MainActivity.java測試漢字轉化為漢語拼音輸出的效果：

 1 package zhangphil.hanyupinyin;
 2 
 3 import java.util.ArrayList;
 4 
 5 import zhangphil.hanyupinyin.HanziToPinyin.Token;
 6 import android.app.Activity;
 7 import android.os.Bundle;
 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("漢字轉拼音輸出: " + getPinYin(s));
17     }
18 
19     // 輸入漢字返回拼音的通用方法函數。
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                 }
30             }
31         }
32 
33         return sb.toString().toUpperCase();
34     }
35 }

結果輸出如圖：
