在使用 JFoenix 控件JFXListView时，如果我使用单元工厂，则无法将材质样式分配给列表。如何使用单元工厂并同时指定JFXListView控件的样式？

这是我的最小、完整和可验证的示例：

demoStyle.css（摘自 JFoenix 演示）

.jfx-list-cell-container {
    -fx-alignment: center-left;
}

.jfx-list-cell-container > .label {
    -fx-text-fill: BLACK;
}

.jfx-list-cell:odd:selected > .jfx-rippler > StackPane, .jfx-list-cell:even:selected > .jfx-rippler > StackPane {
    -fx-background-color: rgba(0, 0, 255, 0.2);
}

.jfx-list-cell {
    -fx-background-insets: 0.0;
    -fx-text-fill: BLACK;
}

.jfx-list-cell:odd, .jfx-list-cell:even {
    -fx-background-color: WHITE;
}

.jfx-list-cell:filled:hover {
    -fx-text-fill: black;
}

.jfx-list-cell .jfx-rippler {
    -jfx-rippler-fill: BLUE;
}

.jfx-list-view {
    -fx-background-insets: 0;
    -jfx-cell-horizontal-margin: 0.0;
    -jfx-cell-vertical-margin: 5.0;
    -jfx-vertical-gap: 10;
    -jfx-expanded: false;
    -fx-pref-width: 200;
}

demoLayout.fxml

<?import com.jfoenix.controls.JFXListView?>
<?import javafx.scene.layout.HBox?>
<HBox
        xmlns="http://javafx.com/javafx/8.0.112"
        xmlns:fx="http://javafx.com/fxml"
        fx:controller="<some>.<valid>.<package>.<structure>.DemoController"
        minWidth="Infinity"
        minHeight="Infinity"
>
    <JFXListView fx:id="jfoenixListViewPlain"/>

    <JFXListView fx:id="jfoenixListViewWithCustomCell"/>
</HBox>

            isResizable = false
            show()
        }
    }
