一通由支付宝道歉事件引发的有关隐衷难点的构思

android调用webservice接口获取新闻

本身的有一篇博客上讲了怎么着基于CXF搭建webservice,service层的接口会被安插到tomcat上,这一篇我就讲一下什么样在安卓中调用那些接口传递参数。

1.在lib中放入ksoap2的jar包并导入

 

366net必赢亚洲手机版,2.在xml 配置文件中参预:

<!-- 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收到不到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.出于是陈设到tomcat上的,为了同处于一个网段,要手机和计算机连一个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.随即本人还境遇了一个难题,就是当传递的新闻复杂时,比如传递list型的一个自定义的类,会冒出难点,当时自家是重写了List艾达pter类,如下所示:

8.调怎么样用ListAdapter类

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