Attention: ne peut pas sérialiser 1.0

Question

Je suis nouveau sur android. Je crée une application de calculatrice qui utilise le service Web. Le service Web est SOAP. donc j'inclus un fichier Ksoap2.jar avec des dépendances. Je prends l'entrée du texte d'édition comme dans le type de données double et le passe au service Web. Cet appel de service Web prend également les paramètres comme doublon et ajout de fonction d'appel du serveur qui a fait l'addition et le résultat de retour.

Mon code de service Web appelant bouton égal android est:

private void onEqualsButtonClick() {   
    secondNumber = Double.parseDouble(editTextInput.getText().toString()); 
    //secondNumber = Integer.parseInt(editTextInput.getText().toString()); 
    editTextInput.setText(""); 
    if(flag==1){    
     //Initialize soap request + add parameters 
     SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);  

     //Use this to add parameters 
     request.addProperty("number1",firstNumber); 
     request.addProperty("number2",secondNumber); 

     //Declare the version of the SOAP request 
     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 

     envelope.setOutputSoapObject(request); 
     try { 
       HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
       androidHttpTransport.debug = true; 
       //this is the actual part that will call the 
       androidHttpTransport.call(SOAP_ACTION, envelope); 
       // Get the SoapResult from the envelope body. 
       SoapObject result = (SoapObject)envelope.bodyIn; 
       if(result != null){ 
        //Get the first property and change the label text 
        editTextInput.setText(""+result.getProperty(0).toString()); 
       } else{ 
        Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show(); 
       } 
     } catch (Exception e) { 
       e.printStackTrace(); 
     }

Quels changements dois-je faire dans le code. Veuillez me suggérer dès que possible ...

Existe-t-il une autre approche API?

Answer 1

Oui, je résous ce problème. J'ai utilisé la classe Marshal pour résoudre ce problème. Le code de la classe de maréchal est la suivante:

import org.ksoap2.serialization.Marshal; 
import org.ksoap2.serialization.PropertyInfo; 
import org.ksoap2.serialization.SoapSerializationEnvelope; 
import org.xmlpull.v1.XmlPullParser; 
import org.xmlpull.v1.XmlPullParserException; 
import org.xmlpull.v1.XmlSerializer; 

public class MarshalDouble implements Marshal { 
    public Object readInstance(XmlPullParser parser, String namespace, String name, 
          PropertyInfo expected) throws IOException, XmlPullParserException { 
     return Double.parseDouble(parser.nextText()); 
    } 


    public void register(SoapSerializationEnvelope cm) { 
     cm.addMapping(cm.xsd, "double", Double.class, this); 
    } 


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

Et de cette classe implimentation est la suivante:

//Marshal class. 
MarshalDouble marshaldDouble = new MarshalDouble(); 
marshaldDouble.register(envelope); 

Espérons que cela vous aidera beaucoup à tous.
