android调用webservice接口获取信息 _webservice

幼敏悟过人，读书辄成诵。这篇文章主要讲述android调用webservice接口获取信息相关的知识，希望能为你提供帮助。
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：
