向量上的Ksoap响应解析错误
向量上的Ksoap响应解析错误
提问于 2013-10-12 00:44:09
我有一个soap webservice和一个用于调用服务的android应用程序。应用程序总是可以工作的，但在上一次网络服务更新之后，出现了一些问题。webservice的更新只是为了删除一些未使用的服务。其他代码未被修改。我的安卓应用程序使用AsyncTask调用服务并返回结果：
public class DownloadDataTask extends AsyncTask<Void, Void, Vector<SoapObject>> {
private static String METHOD_NAME = "getData";
private static String SOAP_ACTION = "http://example.com/getData";
private static String URL = "http://arduino-data-server.appspot.com/dataserver";
private static String NAMESPACE = "http://example.com/";
@SuppressWarnings("unchecked")
@Override
protected Vector<SoapObject> doInBackground(Void... arg0) {
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
Vector<SoapObject> result = (Vector<SoapObject>) envelope.getResponse();
return result;
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}
return null;
}但是我得到了后续的错误：

怎么了？

原因很清楚：
Caused by: java.lang.ClassCastException: org.ksoap2.serialization.SoapObject
cannot be cast to java.util.Vector在此行中，您不能将结果SoapObject转换为Vector值：
Vector<SoapObject> result = (Vector<SoapObject>) envelope.getResponse();试试这个：
SoapObject result = (SoapObject) envelope.getResponse();页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
