javafx基于使用fxml布局的tableview数据绑定用法

来个简单明了的

fxml的tableview数据绑定和java代码方式的数据绑定很像，不同的在于要有一到映射

首先看个目录

1.界面文件Sample.fxml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 
 3 <?import java.lang.*?>
 4 <?import java.util.*?>
 5 <?import javafx.scene.control.*?>
 6 <?import javafx.scene.layout.*?>
 7 <?import javafx.scene.paint.*?>
 8 
 9 <AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" 
10             xmlns:fx="http://javafx.com/fxml" xmlns="http://javafx.com/javafx/2.2"
11             fx:controller="test.SampleController" 
12 >
13   <children>
14     <TableView layoutX="132.0" layoutY="33.0" prefHeight="107.0" prefWidth="310.0" fx:id="tview">
15       <columns>
16         <TableColumn maxWidth="5000.0" minWidth="10.0" prefWidth="137.0" text="用户名" fx:id="colUsername"/>
17         <TableColumn maxWidth="5000.0" minWidth="10.0" prefWidth="143.0" text="密码" fx:id="colPassword"/>
18       </columns>
19     </TableView>
20   </children>
21 </AnchorPane>

2.SampleController代码

 1 package test;
 2 
 3 import java.net.URL;
 4 import java.util.ResourceBundle;
 5 import javafx.collections.FXCollections;
 6 import javafx.collections.ObservableList;
 7 import javafx.fxml.FXML;
 8 import javafx.fxml.Initializable;
 9 import javafx.scene.control.TableColumn;
10 import javafx.scene.control.TableView;
11 import javafx.scene.control.cell.PropertyValueFactory;
12 
13 
14 public class SampleController implements Initializable {
15     
16     @FXML private TableView tview;
17     @FXML private TableColumn colUsername;
18     @FXML private TableColumn colPassword;
19    
20     
21     public void showList(){
22         ObservableList<User> list = FXCollections.observableArrayList();
23         User user = new User();//构建值对象
24          user.setUsername("小六");
25          user.setPassword("123");
26                  
27         colUsername.setCellValueFactory(new PropertyValueFactory("username"));//映射          
28         colPassword.setCellValueFactory(new PropertyValueFactory("password"));          
29         
30          list.add(user);        //list添加值对象
31          tview.setItems(list); //tableview添加list
32        }
33    
34     
35     @Override
36     public void initialize(URL url, ResourceBundle rb) {
37         showList();
38     }    
39 }

View Code

3.User.java代码

package test;
public class User {
    private String username;
    private String password;

    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

View Code

4.Test.java

package test;

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

public class Test extends Application {
    
    @Override
    public void start(Stage stage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));
        Scene scene = new Scene(root);
        stage.setScene(scene);
        stage.show();
    }

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