这实际上是重复的，但是我找不到上一个问题。
您应该使用单元格工厂并在单元格上设置上下文菜单。然后，可以确保仅在非空单元格上设置上下文菜单。（这也使您有机会拥有特定于项目的上下文菜单。）
这是一个简单的例子：
import javafx.application.Application;import javafx.beans.binding.Bindings;import javafx.scene.Scene;import javafx.scene.control.ContextMenu;import javafx.scene.control.ListCell;import javafx.scene.control.ListView;import javafx.scene.control.MenuItem;import javafx.scene.layout.BorderPane;import javafx.stage.Stage;public class ListViewContextMenuExample extends Application { @Override public void start(Stage primaryStage) { ListView<String> listView = new ListView<>(); listView.getItems().addAll("One", "Two", "Three"); listView.setCellFactory(lv -> { ListCell<String> cell = new ListCell<>(); ContextMenu contextMenu = new ContextMenu(); MenuItem editItem = new MenuItem(); editItem.textProperty().bind(Bindings.format("Edit "%s"", cell.itemProperty())); editItem.setonAction(event -> { String item = cell.getItem(); // pre to edit item... }); MenuItem deleteItem = new MenuItem(); deleteItem.textProperty().bind(Bindings.format("Delete "%s"", cell.itemProperty())); deleteItem.setonAction(event -> listView.getItems().remove(cell.getItem())); contextMenu.getItems().addAll(editItem, deleteItem); cell.textProperty().bind(cell.itemProperty()); cell.emptyProperty().addListener((obs, wasEmpty, isNowEmpty) -> { if (isNowEmpty) { cell.setContextMenu(null); } else { cell.setContextMenu(contextMenu); } }); return cell ; }); BorderPane root = new BorderPane(listView); primaryStage.setScene(new Scene(root, 250, 400)); primaryStage.show(); } public static void main(String[] args) { launch(args); }}
