我正在使用由 IntelliJ 的 Gluon 插件生成的 FXML 多视图项目。
我在生成的主视图和辅助视图旁边添加了一个视图（扫描视图），并在 GluonApplication 类中提供了导航代码。
我第一次导航到扫描视图时，文本区域中的一个小括号会闪烁，但我的 android 设备上的软键盘没有显示。当我导航到另一个视图时，键盘会短暂显示并在一秒钟后消失。然后，当我导航回扫描视图时，会显示软键盘。最后，当我使用 android 设备上的后退按钮从 textarea 收回焦点时，无法通过点击 textarea 来重新获得焦点。
欢迎任何信息，干杯。
GluonApplication.java：
public class GluonApplication extends MobileApplication {
public static final String PRIMARY_VIEW = HOME_VIEW;
public static final String SECONDARY_VIEW = "Product View";
public static final String SCAN_VIEW = "Scan View";
public static final String MENU_LAYER = "Side Menu";
@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) -> {
hideLayer(MENU_LAYER);
if (newItem.equals(primaryItem)) {
switchView(PRIMARY_VIEW);
} else if (newItem.equals(secondaryItem)) {
switchView(SECONDARY_VIEW);
} else {
switchView(SCAN_VIEW);
}
});
addLayerFactory(MENU_LAYER, () -> new SidePopupView(drawer));
}
