Question

所以我试图创建一个显示几个数据表的简单JavaFX程序。我有我的模型视图控制器，从我可以告诉一切看起来很清楚。运行应用程序显示没有问题，除了表中没有数据显示。 4个表被初始化，我可以点击它们，这样就可以清楚地设置它们，只是没有数据被放入其中。这是我的代码。

package releaseData;

import java.io.IOException;
import java.util.Observable;

import releaseData.model.ReleaseData;
import releaseData.view.ShowReleaseDataController;
import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;

public class MainApp extends Application {
	private Stage primaryStage;
	//must match the the type of pane in .fxml file
	private AnchorPane rootLayout;
	
	//set up a list 
	private ObservableList<ReleaseData> releaseData = FXCollections.observableArrayList();

	//Constructor
	public MainApp()
	{
		releaseData.add(new ReleaseData("Borderlands", "2K", "11/24/2010", "4/5"));
		releaseData.add(new ReleaseData("Half-Life 2", "Valve", "9/9/2002", "5/5"));
		releaseData.add(new ReleaseData("Far Cry 3", "Activision", "12/1/2012", "5/5"));
		releaseData.add(new ReleaseData("Goat Simulator", "Coffe-Stain", "8/1/2014", "3/5"));
	}
	/**
	@return
	*/
	public ObservableList<ReleaseData> getReleaseData()
	{
		return releaseData;
	}
	
	@Override
	public void start(Stage primaryStage)
	{
		this.primaryStage = primaryStage;
		this.primaryStage.setTitle("Game Data");
		initRootLayout();
	}
	
	public void initRootLayout() 
	{
		try {
			//Load fxml layout
			FXMLLoader loader = new FXMLLoader();
			loader.setLocation(MainApp.class.getResource("view/releaseDataOverview.fxml"));
			rootLayout = (AnchorPane) loader.load();
			
			//Give the controller access
			ShowReleaseDataController controller = loader.getController();
			controller.setMainApp(this);
			
			//Show scene containing the root layout
			Scene scene = new Scene(rootLayout);
			primaryStage.setScene(scene);
			primaryStage.show();
			
		}catch (IOException e) {e.printStackTrace(); }
	}
	
	public Stage getPrimaryStage()
	{
		return primaryStage;
	}
	
	public static void main(String[] args) {
		launch(args);
	}
}

package releaseData.model;

import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;

public class ReleaseData {
	
	private final StringProperty name;
	private final StringProperty publisher;
	private final StringProperty date;
	private final StringProperty rating;
	
	//Constructors
	public ReleaseData() { this(null, null, null, null); }
	
	public ReleaseData(String name, String publisher, String date, String rating){
		this.name = new SimpleStringProperty(name);
		this.publisher = new SimpleStringProperty(publisher);
		this.date = new SimpleStringProperty(date);
		this.rating = new SimpleStringProperty(rating);
	}
	
	//Sets, gets, properties
	public String getName() { return name.get(); }
	public void setName(String name) {this.name.set(name); }
	public StringProperty nameProperty() { return name; }
	
	public String getPublisher() {return publisher.get(); }
	public void setPublisher(String publisher) {this.publisher.set(publisher); }
	public StringProperty publisherProperty() {return publisher; }
	
	public String getDate() { return date.get(); }
	public void setDate(String date) {this.date.set(date); }
	public StringProperty dateProperty() { return date; }
	
	public String getRating() { return rating.get(); }
	public void setRating(String rating) { this.rating.set(rating); }
	public StringProperty ratingProperty() {return rating; }
	
	}

package releaseData.view;

import releaseData.MainApp;
import releaseData.model.ReleaseData;
import javafx.fxml.FXML;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;

public class ShowReleaseDataController {
	
	@FXML
	private TableView<ReleaseData> releaseDataTable;
	@FXML
	private TableColumn<ReleaseData, String> nameColumn;
	@FXML
	private TableColumn<ReleaseData, String> publisherColumn;
	@FXML 
	private TableColumn<ReleaseData, String> dateColumn;
	@FXML
	private TableColumn<ReleaseData, String> ratingColumn;
	
	private MainApp mainApp;
	
	public ShowReleaseDataController() {}
	
	
	@FXML
	private void initializer()
	{
		nameColumn.setCellValueFactory(cellData -> cellData.getValue().nameProperty());
		publisherColumn.setCellValueFactory(cellData -> cellData.getValue().publisherProperty());
		dateColumn.setCellValueFactory(cellData -> cellData.getValue().dateProperty());
		ratingColumn.setCellValueFactory(cellData -> cellData.getValue().ratingProperty());
	}
	
	public void setMainApp(MainApp mainApp)
	{
		this.mainApp=mainApp;
		releaseDataTable.setItems(mainApp.getReleaseData());
	}

}

我已经完成了我能想到的一切以找到问题。如果有人能指出我正确的方向，我将非常感激！

Answer 1

初始化方法应为

public void initialize() {...}

不是initializer()

JavaFX不填充tableColumn中的数据
