Question

基本上我有2个TableView元素。一个是团队，另一个是人。这些tableView中的每一个都有自己的FXML文件，并在控制器中创建。例如，这里是TeamViewController.java：

public class TeamsViewController implements Initializable{

    // Service layer for accessing datastore
    private ServiceLayer serviceLayer = new ServiceLayer();

    @FXML private TableView<Team> tableView;
    private TableColumn<Team, Integer> idCol;

    @Override
    public void initialize(URL location, ResourceBundle resources) {

    tableView.getColumns().addAll(
            this.createIdCol(),
            this.createTeamNameCol(),
            this.createButtonColumn()); // Click to show Team members

    tableView.getItems().setAll(serviceLayer.getAllTeams());

}
// ......... bunch of methods to create the columns, etc.

这里是FXML文件：

<AnchorPane prefHeight="342.0000999999975" prefWidth="568.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="main.ui.TeamsViewController">
  <children>
    <TableView fx:id="tableView" maxHeight="-1.0" maxWidth="-1.0" prefHeight="282.0" prefWidth="568.0" />
  </children>
</AnchorPane>

现在，当我以这种方式将它们分别添加到我的应用程序的主场景时，两个表都正常工作：

public static void main(String[] args) {
    launch(args);
}
@Override
public void start(Stage primaryStage) {
    try {

        // This shows the Team table
        AnchorPane root = (AnchorPane) FXMLLoader.load(getClass().getResource("teamViewController.fxml"));
        Scene scene = new Scene(root,800,400);
        scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
        primaryStage.setScene(scene);
        primaryStage.show();


        //This will show the People table
        AnchorPane people = (AnchorPane) FXMLLoader.load(getClass().getResource("peopleViewController.fxml"));
        scene.setRoot(people);
        primaryStage.setScene(scene);
        primaryStage.show();
    } catch(Exception e) {
        log.severe(e.getMessage());
        e.printStackTrace();
    }
}

Teams Table的最后一列有一个按钮。所以，我被困的地方是：当我单击Team表中的“Detail”按钮时，如何显示团队成员表（People）？提前感谢任何提示！

当您在两个tableviews中使用FXML时，您需要在“详细信息”按钮的单击事件中切换这些fxml。

您还需要更改应用程序文件以更改fxmls。

您可以使用此代码

 public void start(Stage primaryStage) {

    try {
        stage = primaryStage;

        gotohome();

        primaryStage.show();
    } catch (Exception ex) {
        Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
    }
}

public void gotohome() {
    try {
        FXMLController home = (FXMLController) replaceSceneContent("Homepage.fxml");
        home.setApp(this);
    } catch (Exception ex) {
        Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
    }
}

public void gotoproductwise() {
    try {
        SampleController product_wise = (SampleController) replaceSceneContent("/product_wise/product_wise.fxml");
        product_wise.setApp(this);
    } catch (Exception ex) {
        Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
    }
}


private Initializable replaceSceneContent(String fxml) throws Exception {
    FXMLLoader loader = new FXMLLoader();
    InputStream in = Main.class.getResourceAsStream(fxml);
    loader.setBuilderFactory(new JavaFXBuilderFactory());
    loader.setLocation(Main.class.getResource(fxml));
    AnchorPane page;
    try {
        page = (AnchorPane) loader.load(in);
    } finally {
        in.close();
    }

    // Store the stage width and height in case the user has resized the window
    double stageWidth = stage.getWidth();
    if (!Double.isNaN(stageWidth)) {
        stageWidth -= (stage.getWidth() - stage.getScene().getWidth());
    }

    double stageHeight = stage.getHeight();
    if (!Double.isNaN(stageHeight)) {
        stageHeight -= (stage.getHeight() - stage.getScene().getHeight());
    }

    Scene scene = new Scene(page);
    if (!Double.isNaN(stageWidth)) {
        page.setPrefWidth(stageWidth);
    }
    if (!Double.isNaN(stageHeight)) {
        page.setPrefHeight(stageHeight);
    }

   // stage.setOpacity(1);
    stage.setScene(scene);
    stage.sizeToScene();
    return (Initializable) loader.getController();
}

所以你必须将主应用程序类的对象发送到控制器，然后你可以调用切换方法。

将此代码添加到Controller类

 private Main application; 
public void setApp(Main application) {
this.application=application;
}

Javafx基于来自其他TableView的事件加载TableView
