在javafx中从多文本字段检索数据

Question

我正在开发一个应用程序，在这个应用程序中，我应该从我在javaFX控制器中动态创建的文本字段中检索数据，然后用户决定文本字段的数量。因为在第一个视图中我只有一个textfield，所以我很容易地检索它，没有任何问题，但我只是不知道如何在从控制器动态创建文本字段时进行检索。

public void handleButtonActionNext(ActionEvent event) throws IOException{

        String t = textField.getText();
        IntegerStringConverter a = new IntegerStringConverter();
        this.i = a.fromString(t);

        Node node = (Node) event.getSource();
        Stage stage = (Stage) node.getScene().getWindow();
        Scene scene = stage.getScene();
        FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("ProcessusTimeExec.fxml"));
        Parent root = (Parent) fxmlLoader.load();
        scene.setRoot(root); 

        gridPane = (GridPane) FXMLLoader.load(getClass().getResource("ProcessusTimeExec.fxml"));
        Scene secondScene = new Scene(gridPane);
        gridPane.setPadding(new Insets(10, 10, 10, 10));

        this.listTextField = new ArrayList<>();

        for(int n=1; n<=i;n++){
                this.label = new Label("execution Time "+n);

                GridPane.setConstraints(label, 0, n+2);
                GridPane.setConstraints(textField, 1, n+2);
                gridPane.getChildren().add(textField);
                gridPane.getChildren().add(label);
            }

            stage.setScene(secondScene);
    }

public void handleButtonActionAlgo(ActionEvent event) throws IOException{

        Node node = (Node) event.getSource();
        Stage stage = (Stage) node.getScene().getWindow();
        Scene scene = stage.getScene();
        FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("Algo.fxml"));

        Parent root = (Parent) fxmlLoader.load();
        scene.setRoot(root);

        // retrieve the data from the textFields      
    }

类似于：

       TextField textField[] = new TextField[...]; 

      for(int n=1; n<=i;n++) {
            textField[n] = new TextField("input "+n);
            gridPane.getChildren().add(textField[n]);
        }

您可以通过使用.gettext()打印它们来进行测试

    for(int n=1; n<=i;n++) {System.out.println(textField[n].getText());}
