推荐答案
虽然@ fabian的解决方案很好,但在这种情况下,您可以使用 FadeTransition 。它改变了节点的不透明度,非常适合你的情况。
Although @fabian's solution is nice, in this case, you could use a FadeTransition. It alters the opacity of the node and is a good fit for your case.
FadeTransition fadeTransition = new FadeTransition(Duration.seconds(0.1), label);
fadeTransition.setFromValue(1.0);
fadeTransition.setToValue(0.0);
fadeTransition.setCycleCount(Animation.INDEFINITE);
MCVE
import javafx.animation.Animation;
import javafx.animation.FadeTransition;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import javafx.util.Duration;
public class LabelBlink extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
Label label = new Label("Blink");
FadeTransition fadeTransition = new FadeTransition(Duration.seconds(0.1), label);
fadeTransition.setFromValue(1.0);
fadeTransition.setToValue(0.0);
fadeTransition.setCycleCount(Animation.INDEFINITE);
fadeTransition.play();
Scene scene = new Scene(new StackPane(label));
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
Application.launch();
}
}
