如何在JavaFX中让gif动画在特定时间内可见？

import javafx.animation.KeyFrame;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import javafx.util.Duration;

public class GifAnimationExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        // 创建一个ImageView来显示gif动画
        ImageView gifImageView = new ImageView(new Image("path/to/your/gif/file.gif"));

        // 创建一个Timeline来控制gif动画的可见性
        Timeline timeline = new Timeline(
                new KeyFrame(Duration.ZERO, e -> gifImageView.setVisible(true)),
                new KeyFrame(Duration.seconds(5), e -> gifImageView.setVisible(false))
        );
        timeline.setCycleCount(Timeline.INDEFINITE); // 设置循环次数，这里设置为无限循环
        timeline.play(); // 启动Timeline

        StackPane root = new StackPane(gifImageView);
        Scene scene = new Scene(root, 400, 300);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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