我正在使用FXML的多視圖項目，由IntelliJ的Gluon插件生成。Gluon mobile TextArea軟鍵盤問題
我在生成的主視圖和次視圖旁邊添加了一個視圖（掃描視圖），並在GluonApplication類中提供了導航代碼。
我第一次導航到掃描視圖時，一個carret在textarea中閃爍，但我的android設備上的軟鍵盤未顯示。 當我導航到另一個視圖時，鍵盤會短暫顯示自身並在一秒鐘後消失。 然後，當我導航回掃描視圖時，軟鍵盤顯示。 最後，當我用我的android設備上的後退按鈕從textarea撤回焦點時，通過點擊textarea無法重新獲得焦點。
歡迎任何信息，歡呼聲。

@Override
public void init() {
//Add views.
addViewFactory(PRIMARY_VIEW,() -> (View) new PicklistView().getView());
addViewFactory(SECONDARY_VIEW,() -> (View) new ProductView().getView());
addViewFactory(SCAN_VIEW,() -> (View) new ScanView().getView());
//Navigation side bar configuration.
NavigationDrawer drawer = new NavigationDrawer();
NavigationDrawer.Header header = new NavigationDrawer.Header("Gluon Mobile",
"Multi View Project",
new Avatar(21, new Image(GluonApplication.class.getResourceAsStream("/icon.png"))));
drawer.setHeader(header);
final Item primaryItem = new Item("Picklist", MaterialDesignIcon.HOME.graphic());
final Item secondaryItem = new Item("Product", MaterialDesignIcon.DASHBOARD.graphic());
final Item scanItem = new Item("Scan", MaterialDesignIcon.DASHBOARD.graphic());
drawer.getItems().addAll(primaryItem, secondaryItem, scanItem);
drawer.selectedItemProperty().addListener((obs, oldItem, newItem) -> {
