我想在javafx中为我的图像添加计时器,例如,首先显示我的第一张图像约3秒,然后显示我的第二张图像约5秒钟,之后没有显示任何内容。对此有什么看法?

使用Timeline
更新ImageView
的imageProperty
:
import javafx.animation.KeyFrame;
import javafx.animation.KeyValue;
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 ImageDisplayTest extends Application {
@Override
public void start(Stage primaryStage) {
Image image1 = new Image("...") ;
Image image2 = new Image("...") ;
ImageView imageView = new ImageView();
Timeline timeline = new Timeline(
new KeyFrame(Duration.ZERO, new KeyValue(imageView.imageProperty(), image1)),
new KeyFrame(Duration.seconds(3), new KeyValue(imageView.imageProperty(), image2)),
new KeyFrame(Duration.seconds(8), new KeyValue(imageView.imageProperty(), null))
);
timeline.play();
StackPane root = new StackPane();
root.getChildren().add(imageView);
primaryStage.setScene(new Scene(root, 800, 600));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
