Question

我尝试在全屏模式下从一个屏幕切换到另一个屏幕，但只有第一个屏幕在全屏幕上，当我切换到另一个屏幕时，全屏幕无法正常工作。

这是我的代码：

主要

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        Scene scene = new Scene(root);
        primaryStage.setScene(scene);
        primaryStage.setFullScreen(true);
        primaryStage.show();

    }


    public static void main(String[] args) {
        launch(args);
    }
}

    }

    public void nextScreen(ActionEvent actionEvent) throws Exception {

        Stage stage = (Stage) next.getScene().getWindow();
        stage.setFullScreen(true);

        secondScreen.start(stage);
    }

    public void start(Stage window) throws Exception {

        Scene scene = new Scene(root);
        window.setScene(scene);
        window.show();

                </HBox>
            </children>
        </StackPane>
    </children>
</AnchorPane>

SecondScreenController

public class SecondScreenController implements Initializable {

    @FXML
    private Button back;


    @Override
    public void initialize(URL location, ResourceBundle resources) {

    }

    public void start(Stage window) throws Exception {

        Parent root = FXMLLoader.load(getClass().getResource("sample2.fxml"));
        Scene scene = new Scene(root);
        window.setScene(scene);
        window.show();
    }


    public void backScreen(ActionEvent actionEvent) throws Exception {
        Controller firstScreen = new Controller();
        Stage stage = (Stage) back.getScene().getWindow();
        stage.setFullScreen(true);
        firstScreen.start(stage);

    }
}

当我按下按钮全屏模式停止工作时，即使我回到第一个屏幕。知道如何解决这个问题吗？

Answer 1

在window.setFullScreen(true);之前的SecondScreenController.java中添加window.show();。

在window.setFullScreen(true);

之前的Controller.java start()中添加window.show();

JavaFX更改场景保持全屏
