• 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
