java - 检索 WebService 数组 Java(Android)

Question

我必须检查用户是否输入了正确的代码才能检索这些信息。请帮忙！下面的代码是我的 SOAP 的样子：

<retrieveAudioInfoResponse xmlns="http://tempuri.org/">
          <retrieveInfoResult>
            <Info>
              <date>string</date>
              <name>string</name>
              <id>int</id>
              <description>string</description>
              <url>string</url>
            </Info>

这是我为我的班级从网络服务获取数据所做的：

private void retrieveInfo(String code){

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("code", code);


        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;     
        envelope.setOutputSoapObject(request);
        System.out.println(request);

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.debug = true;

        try {

               androidHttpTransport.call(SOAP_ACTION, envelope);
               SoapObject response = (SoapObject) envelope.getResponse();
               infoList = new String[response.getPropertyCount()];

               for(int i=0;i<response.getPropertyCount();i++){ 

               infoList[i] = response.getProperty(i).toString();
               Log.d("This is the response",infoList[i]);
      }      
} 
        catch (Exception e) {           
            e.printStackTrace();
        }       
    }

我的网络服务：

仅供参考，android.os.NetworkOnMainThreadException每当您在主 UI 线程上执行长时间运行的任务时都会发生。所以我确定您正在尝试直接retrieveInfo()在方法内部调用onCreate()。

最好的解决方案是doInBackground()在AsyncTask. 还有一件事，AsyncTask 在 android 中被称为Painless Threading，因为我们程序员一旦实现就不需要担心线程的管理。

您要做的是制作一个 XML 模式来进行比较。
您可以针对 XML 模式运行 SOAP 消息验证。
