本文介绍了一种使用Java实现的将中文字符转换为拼音的方法。通过解析提供的代码片段，可以看到该方法不仅能够处理完整的拼音转换，还能生成拼音的首字母缩写，并确保了较高的准确性。此外，还提供了一个验证内部表格正确性的函数。
亲测有效，代码如下：
//获取的方法类
public class getPinyin {
/**
* 将中文转换成拼音 ，获取拼音，返回拼音加汉子首字母
*
* @param name
* @return
*/
public static String getNameLookupKeys(String name)
{
// TODO : Reduce the object allocation.
HashMap<String, String> keys = new HashMap<String, String>();
ArrayList<Token> tokens = HanziToPinyin.getInstance().get(name);
final int tokenCount = tokens.size();
final StringBuilder keyPinyin = new StringBuilder();
final StringBuilder keyInitial = new StringBuilder();
// There is no space among the Chinese Characters, the variant name
// lookup key wouldn't work for Chinese. The keyOrignal is used to
// build the lookup keys for itself.
final StringBuilder keyOrignal = new StringBuilder();
for (int i = tokenCount - 1; i >= 0; i--)
{
final Token token = tokens.get(i);
if (Token.PINYIN == token.type)
{
keyPinyin.insert(0, token.target);//token.target单个汉字的全拼
keyInitial.insert(0, token.target.charAt(0));//token.target取第一个也就是首拼
} else if (Token.LATIN == token.type)
{
// Avoid adding space at the end of String.
if (keyPinyin.length() > 0)
{
keyPinyin.insert(0, ' ');
}
if (keyOrignal.length() > 0)
{
keyOrignal.insert(0, ' ');
}
keyPinyin.insert(0, token.source);
keyInitial.insert(0, token.source.charAt(0));
}
//LogTag.i("test", "keyOrignal:"+token.source);//token.source单个汉字，
//LogTag.i("test", "keyPinyin:"+keyPinyin.toString());
//LogTag.i("test", "keyInitial:"+keyInitial.toString());
keyOrignal.insert(0, token.source);
keys.put("orignal", keyOrignal.toString());
keys.put("pinyin", keyPinyin.toString());
keys.put("initial", keyInitial.toString());
}
if (keys != null)
{
String pinyin = keys.get("pinyin");//全拼
String initial = keys.get("initial");//缩写
//LogTag.i("test", "Pinyin:"+pinyin.toString());
//LogTag.i("test", "initial:"+initial.toString());
return (pinyin + initial).toUpperCase();//这里比较巧妙 全拼+缩写 like 语句也就全能匹配了
}
return "";
}
/**
* 获取纯拼音
* @param name
* @return
*/
public static String getPinyin(String name){
ArrayList<Token> tokens = HanziToPinyin.getInstance().get(name);
StringBuilder sb = new StringBuilder();
if (tokens != null && tokens.size() > 0) {
for (Token token : tokens) {
if (Token.PINYIN == token.type) {
//Log.i("getPinyin", "Token.PINYIN:"+token.target);

} else {
//Log.i("getPinyin", "!Token.PINYIN:"+token.source);

}
}
}
//Log.i("getPinyin", "中文:"+name+";eng:"+sb.toString().toLowerCase());
return sb.toString().toLowerCase();
}
