Java 适应Oracle'；的通讯簿教程，包括单元格编辑,java,oracle,javafx-2,Java,Oracle,Javafx 2,我是个新手，非常想知道如何在使用FXML时使列单元格可编辑。具体来说，我一直遵循Oracle提供的两个工作示例。第一个（）允许编辑。第二个示例（）在教程的底部建议可以对其进行编辑，但没有说明如何实现这一点我已经阅读了相关问题的答案，但它们超出了我目前的知识水平有人能告诉我如何用尽可能简单的方法来做吗为了节省您查找教程的时间，以下是我直接从Oracle复制的文件：提前谢谢首先是FXMLTableView.java /* * To change this license header

我是个新手，非常想知道如何在使用FXML时使列单元格可编辑。具体来说，我一直遵循Oracle提供的两个工作示例。第一个（）允许编辑。第二个示例（）在教程的底部建议可以对其进行编辑，但没有说明如何实现这一点

我已经阅读了相关问题的答案，但它们超出了我目前的知识水平

有人能告诉我如何用尽可能简单的方法来做吗

为了节省您查找教程的时间，以下是我直接从Oracle复制的文件：

提前谢谢

首先是FXMLTableView.java

/*

 * and open the template in the editor.
 */
package fxmltableview;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;


public class FXMLTableView extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
       primaryStage.setTitle("FXML TableView Example");
       Pane myPane = (Pane)FXMLLoader.load(getClass().getResource
    ("fxml_tableview.fxml"));
       Scene myScene = new Scene(myPane);
       primaryStage.setScene(myScene);
       primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

第二个是控制器：

package fxmltableview;

import javafx.collections.ObservableList;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.TableView;
import javafx.scene.control.TextField;


public class FXMLTableViewController {

    @FXML private TableView<Person> tableView;
    @FXML private TextField firstNameField;
    @FXML private TextField lastNameField;
    @FXML private TextField emailField;



    @FXML
    protected void addPerson(ActionEvent event) {
        ObservableList<Person> data = tableView.getItems();
        data.add(new Person(firstNameField.getText(),
            lastNameField.getText(),
            emailField.getText()
        ));

        firstNameField.setText("");
        lastNameField.setText("");
        emailField.setText("");   
    }
}

最后一个文件是.fxml文件：
