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。

主要从事网页设计、PC网站建设（电脑版网站建设）、wap网站建设（手机版网站建设）、响应式网站开发、程序开发、微网站、小程序设计等，凭借多年来在互联网的打拼，我们在互联网网站建设行业积累了丰富的网站制作、网站设计、网络营销经验，集策划、开发、设计、营销、管理等多方位专业化运作于一体，具备承接不同规模与类型的建设项目的能力。

1.在lib中放入ksoap2的jar包并导入

2.在xml 配置文件中加入：

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;

      money = money + num * price;

    return money;

}

8.调如何用ListAdapter类

ListAdapter adapter = new ListAdapter(this, list,spendMoney); 
lv_goodsList.setAdapter(adapter);
