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
