沒有錯誤，但沒有執行後嘗試catch語句

Question

我想顯示數據使用Web服務。該代碼沒有給出錯誤，但按鈕點擊執行發生最多隻能嘗試的一部分，沒有什麼超出了是執行

try { 
       Toast.makeText(getApplicationContext(), "You r in try", Toast.LENGTH_LONG).show(); 
       HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
       //this is the actual part that will call the webservice 
       androidHttpTransport.call(SOAP_ACTION1, envelope);     
       // Get the SoapResult from the envelope body. 
       SoapObject result = (SoapObject)envelope.bodyIn; 
       //from here nothing executes but gives no error 
       ****if(result != null**) 
       { 
        Toast.makeText(getApplicationContext(), "You r in if", Toast.LENGTH_LONG).show(); 
         //Get the first property and change the label text 
         tv1.setText(result.getProperty(0).toString());  
       } 
       else 
       { 
         Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show(); 
       } 
      } catch (Exception e) { 
       e.printStackTrace(); 
      }       
     } 
    });

你調用拋出異常的幾種方法。

「跳過」代碼表示拋出了異常。

在catch塊中放置麪包以確認。
