本文介绍如何使用Java POI库为Excel工作表设置数据有效性及下拉列表选择，包括具体步骤和代码示例。

手工设置:

excel菜单栏上--数据--有效性--允许--序列,

excel菜单栏上--数据--有效性--输入信息.

程序现实:

首先,http://poi.apache.org/官方下载POI3.2 jar包.

import org.apache.poi.hssf.usermodel.HSSFWorkbook; import org.apache.poi.hssf.usermodel.HSSFSheet; import org.apache.poi.hssf.usermodel.HSSFDataValidation; import org.apache.poi.hssf.usermodel.DVConstraint; import org.apache.poi.hssf.usermodel.HSSFFormulaEvaluator; import org.apache.poi.hssf.util.CellRangeAddressList; import java.io.IOException; import java.io.FileOutputStream; public class PoiTest1{ public static void main(String [] args) throws IOException { HSSFWorkbook wb=new HSSFWorkbook();//excel文件对象 HSSFSheet sheetlist=wb.createSheet("sheetlist");//工作表对象 HSSFSheet sheetview=wb.createSheet("sheetview"); FileOutputStream out=new FileOutputStream("success.xls"); //得到验证对象 HSSFDataValidation data_validation_list = PoiTest1.setDataValidationList((short)1,(short)1,(short)2,(short)2); HSSFDataValidation data_validation_view = PoiTest1.setDataValidationView((short)1,(short)1,(short)2,(short)2); //设置提示内容,标题,内容 data_validation_view.createPromptBox("mm","www.tangxiangcun.com"); //工作表添加验证数据 sheetlist.addValidationData(data_validation_list); sheetview.addValidationData(data_validation_view); wb.write(out); out.close(); } public static HSSFDataValidation setDataValidationList(short firstRow,short firstCol,short endRow, short endCol){ //设置下拉列表的内容 String[] textlist={"列表1","列表2","列表3","列表4","列表5"}; //加载下拉列表内容 DVConstraint constraint=DVConstraint.createExplicitListConstraint(textlist); //设置数据有效性加载在哪个单元格上。 //四个参数分别是：起始行、终止行、起始列、终止列 CellRangeAddressList regions=new CellRangeAddressList(firstRow,firstCol,endRow,endCol); //数据有效性对象 HSSFDataValidation data_validation_list = new HSSFDataValidation(regions, constraint); return data_validation_list; } public static HSSFDataValidation setDataValidationView(short firstRow,short firstCol,short endRow, short endCol){ //构造constraint对象 DVConstraint constraint=DVConstraint.createCustomFormulaConstraint("B1"); //四个参数分别是：起始行、终止行、起始列、终止列 CellRangeAddressList regions=new CellRangeAddressList(firstRow,firstCol,endRow,endCol); //数据有效性对象 HSSFDataValidation data_validation_view = new HSSFDataValidation(regions, constraint); return data_validation_view; } }
