Android解析Excel文档完整示例

MainActivity如下:

package cc.testexcel;

import java.io.File;

import jxl.Cell;

import jxl.CellType;

import jxl.DateCell;

import jxl.NumberCell;

import jxl.Sheet;

import jxl.Workbook;

import android.os.Bundle;

import android.os.Environment;

import android.app.Activity;

/**

 * Demo描述:

 * 利用jxl.jar解析Excel文档

 * 

 * 注意事项:

 * 1 在读取每个单元格cell的时候,要留意其类型(CellType)

 *   这样就可以对不同类型区别对待

 * 2 测试用Excel文档备份于assets文件夹下

 * 

 * 参考资料:

 * Thank you very much
