Question

我对使用Java的PHP-SOAP-Webservice的SOAP请求有问题（使用Android SDK）我有一个SOAP-Helper类。此类连接到SOAP-Service并从服务器获取所有原始数据。在本课程中，我实现了以下方法：

@SuppressWarnings("unchecked")
public static Vector<SoapObject> getLayers(){
    try {
        final String SOAP_ACTION = "http://www.XYZ.ch/YYY/webservice.php/getLayers";
        final String METHOD_NAME = "getLayers";

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        soapEnvelope.dotNet = true;
        soapEnvelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.call(SOAP_ACTION, soapEnvelope);

        Vector<SoapObject> result = (Vector<SoapObject>)soapEnvelope.getResponse();

        return result;

    } catch (Exception e) {
        return null;
    }
}

然后我有一个从helper-class获取数据的类。这是图层的类。

public void getLayers(){
    Vector<SoapObject> vectorLayers = SOAPHelper.getLayers();
    ArrayList<HashMap<String, Object>> myList = new ArrayList<HashMap<String, Object>>();

    for(int i=0; i<vectorLayers.size(); i++){                               
        HashMap<String, Object> layers = new HashMap<String, Object>();
        layers.put("layerId", vectorLayers.get(i).getProperty(0));
        layers.put("layerName", vectorLayers.get(i).getProperty(1));
        myList.add(layers);
    }
}

现在我有这个演员错误：

05-02 13:11:56.866: ERROR/AndroidRuntime(988): Caused by: java.lang.ClassCastException: java.util.Vector

使用调试器，我可以看到Vector中的所有数据。矢量不是空的。所有数据都是正确的。

有什么想法吗？

谢谢抢劫

Answer 1

soapEnvelope.getResponse()返回的对象很可能不是Vector。尝试使用Collection<SoapObject>。

SOAP-Request with Vector，Cast-Error
