  好吧，似乎你需要为 Screen 添加背景颜色而不是 ImageView

  这是一个工作代码和输出

  public class ImageViewBackgroundColor extends Application {
  
      @Override
      public void start(Stage stage) throws Exception {
          try {
              stage.setWidth(Screen.getPrimary().getBounds().getWidth());
              stage.setHeight(Screen.getPrimary().getBounds().getHeight());
              BorderPane borderPane = new BorderPane();
              ImageView imageView = new ImageView();
              Image image = new Image(getClass().getResource("huskar.jpg")
                      .toString());
              imageView.setImage(image);
              imageView.setStyle("-fx-background-color: BLACK");
              imageView.setFitHeight(stage.getHeight());
              imageView.setPreserveRatio(true);
              imageView.setSmooth(true);
              imageView.setCache(true);
              borderPane.setCenter(imageView);
              Scene scene = new Scene(borderPane, Color.BLACK);
              stage.setScene(scene);
              stage.show();
          } catch (Exception e) {
              e.printStackTrace();
          }
      }
  
      public static void main(String[] args) {
          launch(args);
      }
  }
  

  Output
