KSoap2 Android Receive Array of Objects

Question

I am trying to use a .NET webservice in my application where the service returns an array of objects as a response.

This is the format of the response from the web-service.

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetPickersResponse xmlns="http://tempuri.org/">
  <GetPickersResult>
    <Picker>
      <Id>int</Id>
      <StartTime>dateTime</StartTime>
      <EndTime>dateTime</EndTime>
      <PickerCount>int</PickerCount>
    </Picker>
    <Picker>
      <Id>int</Id>
      <StartTime>dateTime</StartTime>
      <EndTime>dateTime</EndTime>
      <PickerCount>int</PickerCount>
    </Picker>
  </GetPickersResult>
</GetPickersResponse>
</soap:Body>
</soap:Envelope>

This is my Java code to get the response from the web-service.

SoapObject request = new SoapObject(NAMESPACE, METHOD_GET_CONTROL);
SoapSerializationEnvelope envelope = 
        new SoapSerializationEnvelope(SoapEnvelope.VER11); 
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);


HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

 try {
             androidHttpTransport.call(SOAP_ACTION_GET_CONTROL, envelope);
            ..........=envelope.getResponse(); //To get the data. }

My question, with what do I replace the "........" in my source code to receive the array of objects as a response from the service ? I need to receive multiple objects and then use their individual data members.

Please help. I am new to Web-services and Ksoap.

@SachinD : I did! Used a modified version of your code and it worked. Thanks a tonne. — Swayam

to get Multiple response just add few lines into your code instead of the ..........=envelope.getResponse();

SoapObject obj1 = (SoapObject) envelope.getResponse();

SoapObject obj2 =(SoapObject) obj1.getProperty(0);


for(int i=0; i<obj2.getPropertyCount(); i++)
{
   SoapObject obj3 =(SoapObject) obj2.getProperty(i);
   int id= Integer.parseInt(obj3.getProperty(0).toString());
   String start_date = obj3.getProperty(1).toString();
   String end_date = obj3.getProperty(2).toString();
   int id= Integer.parseInt(obj3.getProperty(3).toString());
}

If you still have any Problem you can write me.

shouldn't it be: SoapObject obj3 =(SoapObject) obj2.getProperty(i); otherwise for each loop you pick position 0 from the second object instead of looping though its content

I always get Vector as response type, so my solution is:

        HttpTransportSE conn = new HttpTransportSE(url);
        try{
            conn.call(soapAction, envelope); //send request
            Vector<SoapObject> result= (Vector<SoapObject>)envelope.getResponse();

            int length = result.size();
            for(int i=0;i<length; ++i){
                SoapObject so = result.get(i);
                Log.d(TAG,so.getPropertyAsString(3));
            }
        } catch(Exception e){
            e.printStackTrace();
        }

I actually already solved it using a modified version of Sachin D's solution, but nevertheless, thank you for your help. And +1 for the use of Vector. Thanks! :)

}

hear i am passing two parameter and getting list of no. as well this code can use for accessing and displaying String.

this is method

String NAMESPACE = "Your NameSpace" ;

//"http://vladozver.org/";

String METHOD_NAME = "get";//"GetStringList"; //

String SOAP_ACTION = "Your SoapAction";

//"http://vladozver.org/GetSumOfTwoInts";

String URL = "Your Soap Url";

public void involk(String na,String WebMethodName)throws IllegalStateException {

    SoapObject request=new SoapObject(NAMESPACE,WebMethodName);

    PropertyInfo sayHellopi=new PropertyInfo();

    sayHellopi.setName("get");
    sayHellopi.setValue(na);
    sayHellopi.setType(String.class);

    request.addProperty(sayHellopi);

    SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.setOutputSoapObject(request);

    AndroidHttpTransport transp = new AndroidHttpTransport(URL);

    try {
        transp.call(SOAP_ACTION,envelope);
        //ArrayList primitive= (ArrayList) envelope.bodyIn;
        SoapObject primitive= (SoapObject) envelope.bodyIn;

                    if(""!=id1 ){

                        System.out.println("Count " + obj2.getPropertyCount());
                        arraylist.add(""+id1);
                        System.out.println("Array ::::::::::::: " + arraylist);

                    }
                }*/
                  //resText= envelope.bodyIn;

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

            arraylist.add((String) primitive.getProperty(i));

            System.out.println("ForLoop--------------"+primitive.getProperty(i));


            // System.out.println("is result null????????????"+arrayList.listIterator());

        }
        // ListIterator it = arraylist.listIterator();

        //while(it.hasNext())
        // {

        // list.setAdapter(arrayadapter);

    }catch (Exception e){
        System.out.println("Error Value" + e);
        //resText="Error Occur";
        e.printStackTrace();
    }
    //list.setAdapter(arrayadapter);
  //return "";
}

using asynctask

private class AsyncCall extends AsyncTask {

    protected void onPreExecute(){

        super.onPreExecute();

        // pg.setVisibility(View.VISIBLE);
        dialog=new ProgressDialog(MainActivity.this);
        dialog.setIndeterminate(false);
        dialog.setMessage("Loding...");
        dialog.setCancelable(false);
        dialog.show();
    }
    protected Void doInBackground(Void... parms){
      involk(editText,"get");
       // return null;
       // return null;
        return null;
    }

    protected void onPostExecute(Void result){
        super.onPreExecute();
        // tv.setText(displayText);
        if(arraylist.size()!=0){
            dialog.dismiss();
        arrayadapter = new ArrayAdapter<String>( MainActivity.this,
                android.R.layout.simple_list_item_activated_1, arraylist );
            list.setAdapter(arrayadapter);
        }else{
            dialog.dismiss();
            getError();
        }
        // pg.setVisibility(View.INVISIBLE);
    }
}

Button Click event

btn.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view) {

            if(no1.getText().length()!=0&&no1.getText().length()!=0){

                editText=no1.getText().toString();
                AsyncCall task=new AsyncCall();
                task.execute();
            }
        }
    });

I Hope This is will help you friend :)
