你好我有一个必须显示产品的列表视图，但当我点击一个项目时，fxml文件中定义的节点文本消失了，（我们可以看到链接的轮廓，但文本消失了）。有什么问题吗？
结果：
CellProduct.java
import javafx.fxml.FXMLLoader;
import javafx.scene.control.ListCell;
import javafx.scene.layout.HBox;
public class CellProduct extends ListCell<Product> {
private HBox cellView;
private ProductCellController productCellController;
public CellProduct() {
super();
FXMLLoader PRODUCT_CELL_FXML_LOADER = LoaderFile.getFXMLLoader("ProductCellView");
cellView = (HBox) LoaderFile.loadView(PRODUCT_CELL_FXML_LOADER);
productCellController = PRODUCT_CELL_FXML_LOADER.getController();
System.out.println(productCellController);
}
@Override
protected void updateItem(Product product, boolean empty) {
super.updateItem(product, empty);
if (product == null || empty) {
setGraphic(null);
} else {
String urlImage = product.getUrlImage();
double price = product.getPrice();
String name = product.getName();
String shortDescription = product.getShortDescription();
String rating = String.valueOf(product.getRating());
String numberOpinion = String.valueOf(product.getNumberOpinion());
StateProduct state = product.getState();
productCellController.init(urlImage, name, shortDescription, rating, numberOpinion, state);
setGraphic(cellView);
setOnMouseClicked(event -> System.out.println("Click"));
}
}
}
