android调用webservice接口获取信息

我的有一篇博客上讲了如何基于cxf搭建webservice，service层的接口会被部署到tomcat上，这一篇我就讲一下如何在安卓中调用这些接口传递参数。

1.在lib中放入ksoap2的jar包并导入

2.在xml 配置文件中加入：

<!-- 访问网络的权限 --> 
  <uses-permission android:name="android.permission.internet" /> 

3.接下来就要通过代码调用借口了

string wsdl_uri = "http://localhost:8080/webservice4/getnewidport?wsdl";//wsdl 的uri
string namespace = "http://services.he.tsd/";//namespace
string methodname = "getnew";//要调用的方法名称
// 创建httptransportse对象
httptransportse ht = new httptransportse(wsdl_uri);
ht.debug = true;
// 使用soap1.1协议创建envelop对象
soapserializationenvelope envelope = new soapserializationenvelope(soapenvelope.ver11);// 实例化soapobject对象
soapobject object = new soapobject(namespace, methodname);
// 设置参数
object.addproperty("arg0", "hhh");
// 将soapobject对象设置为soapserializationenvelope对象的传出soap消息
envelope.bodyout = object;//由于是发送请求，所以是设置bodyout
envelope.dotnet =false;
envelope.setoutputsoapobject(object);
try{
 // 调用webservice
 ht.call(null, envelope);
 system.out.println("回传的值 ："+envelope.getresponse());
}
catch (exception e) {
 e.printstacktrace();
 string msg=e.getmessage();
 system.out.println(msg);
}

4.若webservice接收不到android传来的值：

  （1）参数名不对

  （2）.net的webservice要将envelope.dotnet =true，否则envelope.dotnet =false

5.由于是部署到tomcat上的，为了同处于一个网段，要手机和电脑连一个wifi。 ipv4查找用window+r，接着cmd，最后ipconfig 即可查到。 

6.要关闭windows防火墙

7.当时我还遇到了一个问题，就是当传递的信息复杂时，比如传递list型的一个自定义的类，会出现问题，当时我是重写了listadapter类，如下所示：

package com.adapter;

8.调如何用listadapter类

listadapter adapter = new listadapter(this, list,spendmoney); 
lv_goodslist.setadapter(adapter);
