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

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.paint.*?>

<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" 
            xmlns:fx="http://javafx.com/fxml" xmlns="http://javafx.com/javafx/2.2"
            fx:controller="test.SampleController" 
>
  <children>
    <TableView layoutX="132.0" layoutY="33.0" prefHeight="107.0" prefWidth="310.0" fx:id="tview">
      <columns>
        <TableColumn maxWidth="5000.0" minWidth="10.0" prefWidth="137.0" text="用户名" fx:id="colUsername"/>
        <TableColumn maxWidth="5000.0" minWidth="10.0" prefWidth="143.0" text="密码" fx:id="colPassword"/>
      </columns>
    </TableView>
  </children>
</AnchorPane>

2.SampleController代码

package test;

import java.net.URL;
import java.util.ResourceBundle;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;


public class SampleController implements Initializable {
    
    @FXML private TableView tview;
    @FXML private TableColumn colUsername;
    @FXML private TableColumn colPassword;
   
    
    public void showList(){
        ObservableList<User> list = FXCollections.observableArrayList();
        User user = new User();//构建值对象
         user.setUsername("小六");
         user.setPassword("123");
                 
        colUsername.setCellValueFactory(new PropertyValueFactory("username"));//映射          
        colPassword.setCellValueFactory(new PropertyValueFactory("password"));          
        
         list.add(user);        //list添加值对象
         tview.setItems(list); //tableview添加list
       }
   
    
    @Override
    public void initialize(URL url, ResourceBundle rb) {
        showList();
    }    
}

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;
    }
}

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);
    }
}

然后达到效果
