Android开发实现读取excel数据并保存为xml的方法

本文实例讲述了Android开发实现读取excel数据并保存为xml的方法。分享给大家供大家参考，具体如下：

前阵子，公司请外面人翻译了一些android中values中的一些strings，然而保存的都是excel格式，如果单纯的将excel中的数据粘贴到指定的xml中的话，工作量非常的大，于是，自己写了个简单的demo，将excel中的数据读取并保存为xml对应的数据，下面的demo和图片展示：

1、数据保存在BeanValue中,包括key和value，方便后续数据读取

package cn.excel.parser;
public class BeanValue {
  private String key;
  private String Value;
  public BeanValue() {
  }
  public String getKey() {
    return key;
  }
  public void setKey(String key) {
    this.key = key;
  }
  public String getValue() {
    return Value;
  }
  public void setValue(String value) {
    Value = value;
  }
}

2、数据解析，包括测试，直接在main方法中进行

package cn.excel.parser;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;

    writeXmlFile(mapList, namelists);

提示：

1、需要引入的包：excel（jxl.jar）xml(dom4j-1.6.1.jar),excel解析poi-3.11-20141221.jar也可以；

2、读取excel会出现乱码问题，可通过WorkbookSettings进行编码格式转换；

3、以上demo针对本人读取的excel表格测试是可以的，具体需要根据你excel中的内容做相应变更即可，

但大体解析流程是一样的！
