java中的连接游戏选择卡

Question

我很难让它正常工作。当用户点击一张卡片时，它应该显示一张图片。这是游戏中与点击动作有关的部分：

ArrayList<CardFace> aFaces = mod.getCards();
    for (int i = 0; i < ConcentrationModel.BOARD_SIZE ; i++) {
        for (int j = 0; j < ConcentrationModel.BOARD_SIZE ; j++) {
            int index = (i * ConcentrationModel.BOARD_SIZE) + j;
            Card fc = (Card)aFaces.get(index);
            Button pic = new Button("",new ImageView(fc.getImage()));
            grid.add(pic, i, j);
            pic.setScaleX(1);
            pic.setScaleY(1);
            pic.setOnAction(event -> System.out.println("Image clicked!!!"));
        }
    }

方法pic.setOnAction（event->..）是应该执行操作的地方。我应该采取什么方法？

您可以创建一个包含ImageView的新Stage来显示您的图片：

public class App extends Application {
    private Stage     imageStage;
    private ImageView imageView;
    @Override
    public void start(Stage primaryStage) throws IOException {
        imageView = new ImageView();
        imageStage = new Stage();
        imageStage.setScene(new Scene(new StackPane(imageView)));
        Button btn = createButton(yourImage);
        VBox root = new VBox(btn);
        Scene scene = new Scene(root, 800, 800);
        primaryStage.setScene(scene);
        primaryStage.show();
    }
    private Button createButton(Image image) {
        Button button = new Button("", new ImageView(image));
        button.setOnAction(e -> {
            imageView.setImage(image);
            imageStage.show();
        });
        return button;
    }
    public static void main(String[] args) {
        launch(args);
    }
}
