更新在本地MS SQL SQL Server在本地更新SQLite數據庫表

Question

我想用服務器中的MS SQL數據庫表更新我的設備中的本地SQLite數據庫表（主）。我在這裏使用SOAP服務。如果在服務器中插入任何新值，則單擊按鈕時，它必須同步並更新表中的新值。我想知道如何去做，下面是我用來調用Web服務的方法。

這裏MANUFACTURERID和MANUFACTURERDESC是我想更新的兩列。

我用下面的鏈接作爲參考，並且有一個類TaskAsync.java使用。我想知道我必須在該課程中寫什麼來調用Web服務。作爲java的新手請幫助我如何做這個同步。 Thanx提前

認沽按照doInbackground在你的異步任務的代碼（）

public boolean getData() 
    { 
     try 
     { 
      SoapObject soReturn ; 
      String [] ParameterName = new String[2]; 
      String [] ParameterValue = new String[2]; 

      ParameterName[0] = "MANUFACTURERID"; 
      ParameterValue[0] = manmasid; 

      ParameterName[1] = "MANUFACTURERDESC"; 
      ParameterValue[1] = manmas; 

       try 
       { 
        objWSConfig.SetURL(URL, WebService); 
        objWSConfig.SetSOAPAction(SoapAction, MethodName); 
        objWSConfig.SetWebService(WebService); 
        objWSConfig.SetMethod(MethodName); 

        ws_Method = objWSConfig.getMethod(); 
        ws_Namespace = objWSConfig.getNamespace(); 
        ws_URL = objWSConfig.getURL(); 
        ws_SOAPAction = objWSConfig.getSOAPAction(); 

        SoapObject request = new SoapObject(ws_Namespace,ws_Method); 

        for(ArryIndex = 0 ; ArryIndex < ParameterName.length ; ArryIndex ++) 
        { 
         PropertyInfo ParaObj = new PropertyInfo(); 
         ParaObj.type = PropertyInfo.OBJECT_CLASS; 
         ParaObj.namespace = ws_Namespace; 
         ParaObj.setName(ParameterName[ArryIndex].toString()); 
         ParaObj.setValue(ParameterValue[ArryIndex].toString()); 
         request.addProperty(ParaObj);  
        } 

        System.setProperty("http.keepAlive", "false"); 

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
        envelope.setOutputSoapObject(request); 
        envelope.dotNet = true; 
        //envelope.encodingStyle = SoapSerializationEnvelope.XSD; 
        envelope.setAddAdornments(true); 

        HttpTransportSE androidHttpTransport = new HttpTransportSE(ws_URL); 
        androidHttpTransport.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>"); 

        androidHttpTransport.call(ws_SOAPAction, envelope); 
        androidHttpTransport.debug = true; 

      if(soReturn != null) 
      { 
       boolean isResult = Boolean.parseBoolean(soReturn.getProperty 
         (WebServiceMethods.Method_Name + "Result").toString()); 

       if(isResult) 
       { 
        String ObjRetu = (String)soReturn.getProperty("ObjData_Retu");   
        Document doc = (Document) objCommon.XMLfromString(ObjRetu); 

        NodeList nodes = doc.getElementsByTagName("Table1"); 
        int TotalNodes = nodes.getLength(); 

        for (int iNode = 0; iNode < TotalNodes ; iNode++) 
        { 
         Element e = (Element) nodes.item(iNode); 

         String MANUFACTURERID = objCommon.getValueFromXML(e, "MANUFACTURERID"); 
         String MANUFACTURERDESC = objCommon.getValueFromXML(e, "MANUFACTURERDESC"); 

         ContentValues values = new ContentValues(); 
         values.put(MANUFACTURERDESC , MANUFACTURERID); 
         values.put(MANUFACTURERDESC, MANUFACTURERDESC); 

         objDBTable.insert(values); 

        } 

        objDBTable.close(); 

        return true; 
       } 
      } 
      else 
      { 
       return false; 
      } 
     }catch (Exception e) 
     { 
      Log.e("Error : ", "Error While Getting Data");
