android调用wenbservice 取值问题

webservice 返回了一个list，类型是自己定义的allUser，取值的时候取不到下面是取值的代码try
{
se.call(soapAction, envelope);
SoapObject response = (SoapObject)envelope.getResponse();
if(response!=null){
request = (SoapObject) envelope.getResult(); String nickname = request.getProperty("pnickname").toString();
list.add(0, nickname);
String name = request.getProperty("name").toString();
list.add(1,name);
String telephone =request.getProperty("ptel").toString();
list.add(2,telephone);
String carNum = request.getProperty("pplatenum").toString();
list.add(3,carNum);
String driverNum = request.getProperty("pjobnum").toString();
list.add(4,driverNum);
String company = request.getProperty("pcompany").toString();
list.add(5,company);
String credit =request.getProperty("pcredit").toString();
list.add(6,credit);
String picture =request.getProperty("pimage").toString();
list.add(7,picture);  
}
} catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
运行时不报错，接收的list是空，该怎么解决AndroidWeb服务
