there is a boring task,boss let me check multiple strings.xml files to findthe differences compare to res/values/strings.xml. Jesus christ! It's 33 kinds of languages in android. I do not want work like a idiot. so,I wrote a program to solve that stupid task.

here is my code.

import java.io.IOException;
import java.nio.charset.Charset;
import java.nio.file.FileVisitResult;
import java.nio.file.FileVisitor;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.attribute.BasicFileAttributes;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**
 * 思路: 
 * 		给定一个res路径,遍历读取以values-开头的目录存到集合中
 * 读取目录下的strings.xml文件,将数据转为键值对HashMap<String,String> source---("XXX","<string name="XXX">ZZZZ</string>");
 * 遍历values/strings.xml默认文件,逐行读取String readLine,同时声明一个List<String> tem; 
 * 		如果该行为<string name="XXX">ZZZZ</string>则提取键XXX,如果匹配到source则tem.add(source.get(key));
 * 		如果该行没有key(注释)或者XML文件头,或者没有匹配的则直接tem.add(readLine);
 * 
 * 注意事项:
 * 		不能在安卓项目中使用! 需要新建一个Java project运行,导入的包全为java.nio.* 下的子类
 * 		如果报错则添加JRE Library
