一中文字转换成拼音的实现方式--基于HanziToPinyin.java类

记录一个文字转换拼音的实现方式，通过开源代码HanziToPinyin.java类实现，网上很通用的一种解决方案，记录一下，可以满足对翻译精度不高的工程要求，可以直接拷贝两个文件到工程中使用。

---------------------------------------------------------------------------------------------------------------------------------------------

先看一下两个工具类的代码：

PinYin.java中会去实例化HanziToPinyin.java类，并调用其中的get()方法，调用之后

汉字返回拼音，字母原样返回

package com.example.chy.hanzi2pinyin;import java.util.ArrayList;public class PinYin {//汉字返回拼音，字母原样返回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 (HanziToPinyin.Token.PINYIN == token.type) {sb.append(token.target);} else {sb.append(token.source);}}}return sb.toString().toLowerCase();//转换为小写
//      return sb.toString().toUpperCase();//转换为大写}
}

HanziToPinyin.java类代码如下：

import android.util.Log;

}

输入效果如图：

但是对于有些文字转化有错误：如 "你"会翻译成"qing"
