Android Webservices 返回多行多列数据(Dataset)
对于之前从事.net或者java开发人员,习惯了从后台获取网格数据(多行多列DataTable),但转行从事android开发,难免会不习惯
Android调用Webservice时,如果返回值是一个boolean或者string值时可以通过下面方式接收返回值:
SoapObject soapObject = (SoapObject) envelope.getResponse();
Re = soapObject.getProperty("twgp")
如果接收是一行值时也可以通过上面的方式去获取,但是如果返回的是多行多列或者一行多列的数据集时就比较麻烦了,上面的方法不管用,不然的话接收到的值永远是第一行的值,所以对于那种多行多列的返回值时,如下面的webservice:
//运价查询 @SuppressWarnings("unchecked") @Repository("priceDao") public class PriceDao extends BaseOraDao { public List getPrice(String fromPort, String toPort){ List foo; StringBuffer sb = new StringBuffer(); sb.append("select max(price20gp) as price20GP,max(price40gp) as price40gp,max(price40h) "); sb.append("as price40h from "); sb.append("(select * from nqprice_main n where n.feetype='水运费' and n.fromport='"); sb.append(fromPort).append("' "); sb.append("and n.toport='").append(toPort).append("' "); sb.append("and n.endday is null order by n.beginday desc) where rownum<=2"); foo = getNqoraJdbcTemplate().query(sb.toString(), new RowMapper() { public Object mapRow(ResultSet rs, int rowNum) throws SQLException { Price dm = new Price(); dm.setTwgp(String.valueOf(rs.getDouble("price20GP"))); dm.setFtgp(String.valueOf(rs.getDouble("price40gp"))); dm.setFtgp(String.valueOf(rs.getDouble("price40h"))); return dm; } }); return foo; } } } }
经过一天研究发现有一种办法获取:
//构造数据 ArrayList<String> list = null; //web service请求 ht.call(null, envelope); //得到返回结果 result = (SoapObject) envelope.bodyIn; for (int i = 0; i < result.getPropertyCount(); i++) { SoapObject soapChilds =(SoapObject)result.getProperty(i); list.add(soapChilds.getProperty("price20GP").toString()); } //这样list就包含了返回列price20GP的数据
