字符串不能轉換爲org.ksoap2.serialization.SoapPrimitive

Question

我有webservice，返回字符串值「1」或「-1」，但字符串中的數字。

我有錯誤的使用不能從字符串轉換爲org.ksoap2.serialization.SoapPrimitive Asunc任務

全AsuncTask類代碼：

public class LoginAsync extends AsyncTask<Void, Void, String> { 

Activity mActivity; 
Context context; 

ProgressDialog progressDialog; 

public LoginAsync(Activity activity, ProgressDialog progressDialog, 
     Context context) { 
    super(); 
    this.progressDialog = progressDialog; 
    this.mActivity = activity; 
    this.context = context; 
} 

@Override 
protected String doInBackground(Void... voids) { 
    SoapPrimitive resultRequestSOAP = null; 

    try { 
     final String NAMESPACE = "http://ws.sams.com"; 
     final String URL = "http://sams-app.com:8080/webService/services/LoginActvityWs?WSDL"; // usint 
                           // // 
                           // // 
                           // // 
                           // localhost 
     final String METHOD_NAME = "login"; 
     final String SOAP_ACTION = "http://ws.sams.com/login"; 

     SharedPreferences prefs = PreferenceManager 
       .getDefaultSharedPreferences(context); 
     String user = prefs.getString("login1", "0"); 
     String pass = prefs.getString("password1", "0"); 
     // Calling Login Method 
     SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

     // First Reques for USER NAME . 
     PropertyInfo pi = new PropertyInfo(); 
     pi.setName("username"); 
     pi.setValue(user); 
     pi.setType(String.class); 
     request.addProperty(pi); 

     // Second Reques for USER NAME . 
     PropertyInfo pi2 = new PropertyInfo(); 
     pi2.setName("password"); 
     pi2.setValue(pass); 
     pi2.setType(String.class); 
     request.addProperty(pi2); 

     // Getting Request Result , Will get TID . 
     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
       SoapEnvelope.VER11); 

     envelope.setOutputSoapObject(request); 

     HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 

     androidHttpTransport.call(SOAP_ACTION, envelope); 
     resultRequestSOAP = (SoapPrimitive) envelope.getResponse(); 

     return String.valueOf(resultRequestSOAP); 

    } 

    catch (SocketTimeoutException e) { 
     return "error"; 

    } 

    catch (ConnectTimeoutException e) { 
     return "error"; 

    } 

    catch (XmlPullParserException e) { 

     return "error"; 

    } catch (IOException e) { 

     return "error"; 
    } 

    catch (NullPointerException e) { 

     return "error"; 

    } 

} 

@Override 
protected void onPostExecute(String result) { 

    // If any error oceeared duaring get TID 
    if (result.equalsIgnoreCase("error")) { 
     final AlertDialog.Builder alertDialog = new AlertDialog.Builder(
       mActivity); 

     alertDialog.setTitle("يوجد مشكلة بالاتصال او السيرفر");

         LoginAsync asynTask = new LoginAsync(mActivity, 
           progressDialog, mActivity 
             .getApplicationContext()); 
         asynTask.execute(); 
        } 
       }); 

     // No Button Action 
     alertDialog.setNegativeButton("لا", 
       new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) {

        } 
       }); 

     alertDialog.show(); 

    } 
    // IF pass or user Filed . 
    else if (Integer.parseInt(result.toString()) == -1) { 

     final AlertDialog.Builder alertDialog = new AlertDialog.Builder(

         Toast.makeText(mActivity.getApplicationContext(), 
           "thank you for using SAMS app", 
           Toast.LENGTH_LONG).show(); 
         mActivity.finish(); 
        } 
       }); 

     alertDialog.show(); 

    } 

    else if (Integer.parseInt(result.toString()) == 0) { 

     SharedPreferences prefs = PreferenceManager 
       .getDefaultSharedPreferences(context); 
     prefs.edit().putInt("TID", Integer.parseInt(result.toString()))

     asynTask.execute(); 

    } 

    // For correct Login ! 
    else { 
     progressDialog.dismiss(); 
     if (Integer.parseInt(result.toString()) >= 1) {

Answer 1

這發生在我身上一次，我從SoapPrimitive更改爲Object，然後投它，它的工作。所以試試吧。這可能並不相關，但是如果您正在使用dotnet編寫Web服務，請確保使用envelop.dotnet = true;在您的信封中指定該服務。

Answer 2

我遇到了同樣的問題，就像Jacky Nguyen說的那樣解決問題。
這裏是例子，希望它有幫助！

替換
// SoapPrimitive resultRequestSOAP = null;
by
Object resultRequestSOAP = null;

和替換

// resultRequestSOAP =（SoapPrimitive）envelope.getResponse（）;
by
resultRequestSOAP =（Object）envelope.getResponse（）;

Answer 3

SoapPrimitive response = (SoapPrimitive) envelope.getResponse(); 
    string result = response.toString();
