這裏是我shouldve包括FXML文件。我把它縮小到了真正只顯示按鈕聲明的地方，因爲問題來自哪裏。

 <Button fx:id="calculate" layoutX="976.0" layoutY="23.0" mnemonicParsing="false" onAction="#calculateTotal" text="Calculate" />

要了解按鈕實際上是射擊，你應該簡單地把一個的System.out.println（」你只是按下按鈕「）;在頂部的calculateTotal處理程序中。如果您在按下按鈕後看到此代碼，則知道該按鈕正在觸發，並且您的問題存在於其他位置。要嘗試查看代碼是否拋出了未捕獲的錯誤，請將所有代碼放在try塊中，然後在catch框中使用Exception ex並打印ex.toString（）; – Sedrick

您沒有爲動作定義EventHandler，試試這個代碼片段：

calculateTotal.setOnAction(new EventHandler<ActionEvent>() { 
     @Override 
     public void handle(ActionEvent event) { 
      // row1 
      int sal1 = Integer.parseInt(sale1.getText()); 
      int taxx1 = Integer.parseInt(tax1.getText()); 
      int frei1 = Integer.parseInt(freight1.getText()); 
      int lab1 = Integer.parseInt(labor1.getText()); 
      int cos1 = Integer.parseInt(cost1.getText()); 
      int result1 = sal1 + taxx1 + frei1 + lab1 + cos1; 
      profit1.setText(profit1.getText() + result1); 
      ...... 
     } 
    });

我只是試過這個，但在最後一個支架即時通訊中得到一個錯誤，說「到達解析文件結束」。任何想法爲什麼？ – bills

好吧，我忘了文件末尾的括號。我修復了這個錯誤。但是當我添加事件句柄時，如果按下按鈕 – bills

爲calculate（）方法添加@FXML註釋，則不會發生任何事情，如果它不工作將該代碼片段複製到initialize（）方法中。 –
