发送SOAP请求时出现问题

Question

我正在使用以下代码发送SOAP请求。

 String str = new StringBuilder("POST /WrenchTelLink/WrenchENTService.asmx HTTP/1.1\n")
              .append("Host: 59.160.183.14\n")
              .append("Content-Type: text/xml; charset=utf-8\n")
              .append("Content-Length: LLLLLL\n")
              .append("SOAPAction: \"http://WrenchGlobal/GetToDoList\"\n ")
              .append("<?xml version=\"1.0\" encoding=\"utf-8\"?>")
              .append("<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/\">\n")
              .append("<soap:Body>\n")
              .append("<GetToDoList xmlns=\"http://WrenchGlobal/\">\n")
              .append("<viPeriod>IIIIII</viPeriod>\n")
              .append("<vsUserID>SSSSSS</vsUserID>\n")
              .append("</GetToDoList>\n")
              .append("</soap:Body>\n")
              .append("</soap:Envelope>\n").toString();
 String temp = str.replaceAll("LLLLLL",Integer.toString(str.length()))
   .replaceAll("SSSSSS",ph).replaceAll("IIIIII",Integer.toString(period));
  HttpClient httpclient = new DefaultHttpClient();
  HttpPost httppost = new HttpPost(url);

  try
   {
      StringEntity se = new StringEntity(temp,HTTP.UTF_8);

      se.setContentType("text/xml");  
      httppost.setHeader("Content-Type","application/soap+xml;charset=UTF-8");

      httppost.setEntity(se);  
      BasicHttpResponse httpResponse = (BasicHttpResponse)httpclient.execute(httppost);

      if(httpResponse.getStatusLine().toString()!="") 
         Toast.makeText(TelLinkActivity.this, httpResponse.getStatusLine().toString()
                    , Toast.LENGTH_SHORT).show();
      else
          Toast.makeText(TelLinkActivity.this,"Failed", Toast.LENGTH_SHORT).show();

     }
    catch(ClientProtocolException e)
    {
      e.printStackTrace();
    }
    catch(IOException e)
    {
      e.printStackTrace();  
    }    

它没有显示任何TOAST消息。我没有得到我应该从中理解的东西。它根本不起作用。谁能告诉我代码是否有问题......？

通过runOnUiThread显示ui线程中的Toast，例如

runOnUiThread(new Runnable() {
    public void run() {
      Toast.makeText(TelLinkActivity.this,"Failed", Toast.LENGTH_SHORT).show();
    }
});
