ListView似乎已经有了一个滚动条。我希望滚动条始终可见。原因是因为我在它上面放了一个标题,在滚动条和标题之间的角落里放了一个按钮。如何让ListView滚动条始终显示?

您可以将其放入适当大小的ScrollPane并将ScrollPane的vbar策略设置为ALWAYS:
@Override
public void start(Stage primaryStage) throws Exception {
ScrollPane pane = new ScrollPane();
ListView<String> list = new ListView<String>();
ObservableList<String> items = FXCollections.observableArrayList(
"Single", "Double", "Suite", "Family App");
list.setItems(items);
pane.prefWidthProperty().bind(list.widthProperty());
pane.prefHeightProperty().bind(list.heightProperty());
pane.setContent(list);
pane.setVbarPolicy(ScrollPane.ScrollBarPolicy.ALWAYS);
Group group = new Group();
group.getChildren().add(pane);
Scene scene = new Scene(group, 500, 500);
primaryStage.setScene(scene);
primaryStage.show();
}
