android调用webservice接口获取信息

这篇文章主要为大家详细介绍了android调用webservice接口获取信息,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

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;

      money = money + num * price;

    return money;
  }
}

8.调如何用ListAdapter类

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