想改进这个问题？将问题更新为 on-topic对于堆栈溢出。

我正在尝试从一个窗口切换到另一个窗口。
这是我的代码:

public class SelectTypeController implements Initializable {

    @FXML
    private Button buttonVai;
    @FXML
    private ComboBox<String> comboBox;
    @FXML
    private AnchorPane rootPane;

    @Override
    public void initialize(URL location, ResourceBundle resources) {
        ObservableList<String> observableListOfAccomodations = FXCollections.observableArrayList("1", "2", "3");
        comboBox.setItems(observableListOfAccomodations);
        buttonVai.setDisable(true);
    }

    @FXML
    public void comboChanged() {
        buttonVai.setDisable(false);
    }

    @FXML
    public void showCrudPage() {
        switch (comboBox.getValue()) {
            case "3":
                showCrudPageRestaurantScene();
                break;
        }
    }
    // this is giving problem
    public void showCrudPageRestaurantScene() {
        try {
            Parent parent = FXMLLoader.load(SelectTypeController.class.getResource("/crud_restaurant.fxml"));
            Stage stage = new Stage();
            Scene scene = new Scene(parent);
            stage.setScene(scene);
            stage.show();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

它管理以下 fxml View
select_type.fxml

<AnchorPane
        fx:id="rootPane"
        xmlns:fx="http://javafx.com/fxml/1" fx:controller="controllers.SelectTypeController" maxHeight="-Infinity"
        maxWidth="-Infinity"
        minHeight="-Infinity" minWidth="-Infinity" prefHeight="800.0" prefWidth="1280.0"
        xmlns="http://javafx.com/javafx/11.0.1">
    <ImageView fitHeight="800.0" fitWidth="1280.0" pickOnBounds="true">
        <Image url="images/3156482.jpg"/>
    </ImageView>
    <Pane layoutX="440.0" layoutY="307.0" opacity="0.8" prefHeight="200.0" prefWidth="400.0"
          style="-fx-background-color: #06BCAD; -fx-background-radius: 20;"/>
    <Pane layoutX="336.0" layoutY="206.0" prefHeight="336.0" prefWidth="608.0">
        <Label layoutX="200.0" layoutY="29.0" text="Seleziona una tipologia">
            <font>
                <Font size="20.0"/>
            </font>
        </Label>
        <Button fx:id="buttonVai" layoutX="260.0" layoutY="250.0" mnemonicParsing="false"
                onMouseClicked="#showCrudPage"
                style="-fx-background-color: #0078D7;" text="Vai" textFill="white"/>
    </Pane>
    <ComboBox fx:id="comboBox" layoutX="512.0" layoutY="371.0" prefHeight="30.0" prefWidth="292.0"
              promptText="Seleziona una tipologia"
              onAction="#comboChanged"/>

</AnchorPane>

我想要点击 Vai按钮，我被重定向到:

public class CrudRestaurant {
    @FXML
    private Label labelDescription;
}

哪个管理
crud_restaurant.fxml

<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="1080.0"
            fx:controller="controllers.CrudRestaurant"
            prefWidth="1920.0" xmlns="http://javafx.com/javafx/11.0.1" xmlns:fx="http://javafx.com/fxml/1">
    <Label layoutX="828.0" layoutY="415.0" text="Placeholder"/>
</AnchorPane>

不幸的是，我遇到了一个异常(exception):

javax.xml.stream.XMLStreamException: ParseError at [row,col]:[3,6]

我该如何解决？javaf

Answer 1

已解决
我复制了 <?xml version="1.0" encoding="UTF-8"?>在 crud_restaurant.fxml文件。我的错。
只需删除一个多余的声明。
