私はクラスのTextViewのテキストを設定できません

Question

私はSOAPを使用しています、AsyncTaskクラスでは、私はドライバIDText、shipmentIDText、freightShipment textviewsのテキストを設定しようとしていますが、setText（）あなたは文字列ではないのTextViewとしてdriverIDTextを宣言し、だから、TextViewのために1つの以上のparamを作成し、onPostExecuteでのTextViewのデータをOnCreate関数からdriverIDText（のTextView）を送信し、設定

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_show_up); 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 


     TextView driverIDText = (TextView) findViewById(R.id.text_DriverID); 
     TextView shipmentIDText = (TextView) findViewById(R.id.text_ShipmentID); 
     TextView freightShipment = (TextView) findViewById(R.id.text_FreightShipment); 

new RetrieveFeedTask(driverIDText.getText.toString(), 
shipmentIDText.getText().toString(), 
freightShipment.getText().toString() 
).execute(); 

    } 

    class RetrieveFeedTask extends AsyncTask<String, String, Void> { 

     private String driverIDText, shipmentIDText, freightShipment; 

     RetrieveFeedTask(String driverIDText, String shipmentIDText, String freightShipment) { 
      this.driverIDText = driverIDText; 
      this.shipmentIDText = shipmentIDText; 
      this.freightShipment = freightShipment; 
     } 


     protected Void doInBackground(String... urls) { 


      SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

      request.addProperty("DriverID", driverIDText); 
      request.addProperty("ShipmentID", shipmentIDText); 
      request.addProperty("FreightShipment", freightShipment); 

      SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 

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

      try { 
       HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 

       androidHttpTransport.call(SOAP_ACTION, envelope); 

       SoapObject result = (SoapObject) envelope.bodyIn; 
       if (result != null) { 

        // HERE IS PROBLEM IN SETTEXT() 
        driverIDText.setText(result.getProperty(0).toString()); 


       } else { 
        Toast.makeText(getApplicationContext(), "Login Failed!", Toast.LENGTH_LONG).show(); 
       } 

      } catch (Exception e) { 
       e.printStackTrace(); 

      } 
      return null; 
     } 

    }

インサイドAsyncTask：

は、ここに私のコードです。

例：

class RetrieveFeedTask extends AsyncTask<String, String, String> { 

     private String driverIDText, shipmentIDText, freightShipment; 

     private TextView driverIDTextTv; 

     RetrieveFeedTask(String driverIDText, String shipmentIDText, String freightShipment, TextView textView) { 
      this.driverIDText = driverIDText; 
      this.shipmentIDText = shipmentIDText; 
      this.freightShipment = freightShipment; 
      driverIDTextTv = textView; 
     } 

     @Override 
     protected void onPostExecute(String text) { 
      super.onPostExecute(text); 

      driverIDTextTv.setText(text); 
     } 

     protected String doInBackground(String... urls) { 


      String localDriverId = ""; 

      SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

      request.addProperty("DriverID", driverIDText); 
      request.addProperty("ShipmentID", shipmentIDText); 
      request.addProperty("FreightShipment", freightShipment); 

      SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 

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

      try { 
       HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 

       androidHttpTransport.call(SOAP_ACTION, envelope); 

       SoapObject result = (SoapObject) envelope.bodyIn; 
       if (result != null) { 

        // HERE IS PROBLEM IN SETTEXT() 
//     driverIDText.setText(result.getProperty(0).toString()); 

        localDriverId = result.getProperty(0).toString(); 


       } else { 
        Toast.makeText(getApplicationContext(), "Login Failed!", Toast.LENGTH_LONG).show(); 
       } 

      } catch (Exception e) { 
       e.printStackTrace(); 

      } 
      return localDriverId; 
     } 

    } 

、あなたはこのようにAsyncTaskを呼び出すことができ、このラインで

new RetrieveFeedTask(driverIDText.getText.toString(), 
       shipmentIDText.getText().toString(), 
       freightShipment.getText().toString(), driverIDText 
     ).execute();
