请告诉我如何才能做到这一点。
你好,Matt。

您可以使用JAXB作为xml到Java对象转换器。下面是这些示例:尝试封送/取消封送元素

所以我最后做的就是创建一个自定义控件。我将要动态创建的xml分离到它自己的名为listItem.fxml的fxml文件中

listItem.fxml

  <fx:root alignment="CENTER_LEFT" prefHeight="78.0" prefWidth="363.0" stylesheets="@../css/styles.css" type="javafx.scene.layout.HBox" xmlns="http://javafx.com/javafx/8.0.121" xmlns:fx="http://javafx.com/fxml/1">

  <!-- xml for listitem comes here -->

</fx:root>
之后,每次我想使用自定义组件时,我都会创建一个新组件,如下所示:

ListItemControl clientBoxControl = new ListItemControl();

如果您说明使用哪个XML库,您可能会得到更好的帮助。
public class ListItemControl extends HBox {
       // associate the control to the fxml
  public ListItemControl() {
        FXMLLoader fxmlLoader = new 
          FXMLLoader(getClass().getResource("/com/company/fxml/listItem.fxml"));
        fxmlLoader.setRoot(this);
        fxmlLoader.setController(this);

        try {
            fxmlLoader.load();
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

    }
ListItemControl clientBoxControl = new ListItemControl();
