Android parse Object KSOAP

问题

I'd like to know how do I parse the output of SOAP. My current code is the following:

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);

    Object response = (Object) envelope.getResponse();   

    Log.e("Output:", response.toString());

}catch (Exception e){
    Log.e("Error:", e.getCause().toString());
}

The output of the response is this:

[{"category_id":767,"parent_id":663,"name":"Walk"}, {"category_id":768,"parent_id":767,"name":"Google"}, {"category_id":764,"parent_id":697,"name":"Yellow"}]

So, how do I get these values separately?

I just want to let you know that If I change this line:

Object response = (Object) envelope.getResponse();   

To this:

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

I get the following error:

Thanks.

From your comments you need to parse the json array.

 JSONArray jr = new JSONArray("jsonstring");
 for(int i =0 ; i< jr.length();i++)
 {
 JSONObject jb =(JSONObject) jr.get(i);  
 String categoryid = jb.getString("category_id");
 String parent_id = jb.getString("parent_id");
 String name = jb.getString("name");
 }

Solved thanks to @Raghunandan. Also, it retrieves the right encoding, which is awesome, since that json_encode put special characters on strings.

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);

    SoapObject rep = (SoapObject) envelope.bodyIn;

    JSONArray jr = new JSONArray(rep.getPropertyAsString(0));
    for(int i =0 ; i< jr.length();i++)
     {
         JSONObject jb =(JSONObject) jr.get(i);  

         String name = jb.getString("name");
         Log.e("value:", name);
     }

}catch (Exception e){
    Log.e("Error:", e.toString());
}
