Stringで単純なメソッドを実行するためにSOAPリクエストが必要なWebサービスがあります。今、私はこのWebサービスを使用するためにAndroidでアプリを作成し、データをシリアル化して、SOAP経由でWebサービスに送信したいと考えています。

ここにいくつかのコードがあります：

public class SendedLocation implements Serializable {
    public String MESSAGE;

    public SendedLocation() {
    }

    public SendedLocation(int mId, float mLongitude, float mLatitude) {

        MESSAGE = String.valueOf(mId) + ";" + String.valueOf(mLongitude) + ";" +  String.valueOf(mLatitude);
    }

    public Object getProperty(int arg0) {

        switch (arg0) {
        case 0:
            return MESSAGE;
        }

        return null;
    }

    public int getPropertyCount() {
        return 1;
    }

    public void getPropertyInfo(int index, Hashtable arg1, PropertyInfo info) {
        switch (index) {
        case 0:
            info.type = PropertyInfo.STRING_CLASS;
            info.name = "MESSAGE";
            break;
        default:
            break;
        }
    }

    public void setProperty(int index, Object value) {
        switch (index) {
        case 0:
            MESSAGE = value.toString();
            break;
        default:
            break;
        }
    }

}

public void callWebService(int ID, float Longitude, float Latitude) {
    try {
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(
                URL);

        SendedLocation mSended = new SendedLocation(ID, Longitude, Latitude);

        PropertyInfo p1 = new PropertyInfo();
        p1.setName("mSended");
        p1.setValue(mSended);
        p1.setType(mSended.getClass());
        request.addProperty(p1);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);

        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);

        envelope.addMapping(NAMESPACE, "mSended", mSended.getClass());

        MarshalString marshalString = new MarshalString();

        marshalString.register(envelope);

        // Make the soap call.
        androidHttpTransport.call(SOAP_ACTION, envelope);

        Object results = (Object) envelope.getResponse();
        // to get the data String
        // resultData=result.getProperty(0).toString();
        String temp = results.toString();
        System.out.println(temp);
    } catch (Exception aE) {
        System.out.println(aE.toString());
    }
}
public class MarshalString implements Marshal 
{


    public Object readInstance(XmlPullParser parser, String namespace, String name, 
            PropertyInfo expected) throws IOException, XmlPullParserException {

        return String.valueOf(parser.nextText());
    }


    public void register(SoapSerializationEnvelope cm) {
         cm.addMapping(cm.xsd, "string", String.class, this);

    }


    public void writeInstance(XmlSerializer writer, Object obj) throws IOException {
           writer.text(obj.toString());
        }

}

そして、私は次のようにonCreate（）でこのcallWebService（）メソッドを呼び出しています：

callWebService(ID , (float)location.getLongitude() , (float)location.getLatitude());

次に、アプリを実行すると、gpsから修正が取得されますが、データの送信に関しては、Webサービスを実行すると次のようになります。

java.lang.RuntimeException: Cannot serialize...

誰かが私にそれを機能させるために何を追加すべきか説明できますか？マーシャルクラスを使う手がかりを試した後、私は本当にわかりません...

データの送信にSOAPEnvelopeを使用してみてください、SOAPEnvelopeの構文：

final String envelope = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"+
                      "<SOAP-ENV:Envelope SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\" " +
                      "xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" " +
                      "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" " +
                      "xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"" +
                      " xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\" " +
                      "xmlns:tns=\"urn:registerwsdl\">"+
                      "<SOAP-ENV:Body>"+
                      "<tns:register " +
                      "xmlns:tns=\"urn:registerwsdl\">"+
    "<your_feild_name xsi:type=\"xsd:string\">"+"your_value"+"</your_feild_name>"+



                      "</tns:register>"+

                               // "</SOAP-ENV:Body></SOAP-ENV:Envelope>",Name,Email,Password,Status,Type,Date];
                               "</SOAP-ENV:Body></SOAP-ENV:Envelope>";

次に、この関数でこのエンベロープを使用すると、SoapEnvelopeで複数の値を渡すことができます

String CallWebService(String url,
            String soapAction,
           String envelope)  {
          final DefaultHttpClient httpClient=new DefaultHttpClient();
          // request parameters

          HttpParams params = httpClient.getParams();
             HttpConnectionParams.setConnectionTimeout(params, 20000);
             HttpConnectionParams.setSoTimeout(params, 25000);
             // set parameter
          HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), true);

          // POST the envelope
          HttpPost httppost = new HttpPost(url);
          // add headers
             httppost.setHeader("soapaction", soapAction);
             httppost.setHeader("Content-Type", "text/xml; charset=utf-8");

             String responseString="";
             try {

              // the entity holds the request
           HttpEntity entity = new StringEntity(envelope);
           httppost.setEntity(entity);

           // Response handler

           ResponseHandler<String> rh=new ResponseHandler<String>() {
            // invoked when client receives response

               public String handleResponse(HttpResponse response)
              throws ClientProtocolException, IOException {

             // get response entity
             HttpEntity entity = response.getEntity();


             // read the response as byte array
                   StringBuffer out = new StringBuffer();
                   byte[] b = EntityUtils.toByteArray(entity);

                   // write the response byte array to a string buffer
                   out.append(new String(b, 0, b.length));

                   return out.toString();
            }
           };

           responseString=httpClient.execute(httppost, rh); 

          }
             catch (Exception e) {
              Log.v("exception", e.toString());
          }

             xml =  responseString.toString();
             // close the connection
             System.out.println("xml file ------"+xml);
          httpClient.getConnectionManager().shutdown();
          return responseString;
         }

最後に、任意のXMLパーサーを使用してXML出力を解析します。
