但是在运行时,当我应用第二个场景时,场景不会根据舞台的高度和宽度进行调整。场景的高度和宽度保持不变。
所以任何解决方案?

这是因为舞台会根据场景调整其大小,除非明确指示......
这是一个解决方案:
stage.setScene(scene2);
stage.setHeight(1000);
stage.setWidth(1000);
示例应用程序:
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;
public class Test extends Application {
@Override
public void start(final Stage stage) throws Exception {
AnchorPane anchor1 = new AnchorPane();
final Scene scene1 = new Scene(anchor1, 250, 250);
Button boton1 = new Button();
anchor1.getChildren().add(boton1);
AnchorPane anchor2 = new AnchorPane();
final Scene scene2 = new Scene(anchor2, 500, 500);
Button boton2 = new Button();
anchor2.getChildren().add(boton2);
boton2.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent arg0) {
// TODO Auto-generated method stub
stage.setScene(scene1);
stage.setHeight(1000);
stage.setWidth(1000);
}
});
boton1.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent arg0) {
// TODO Auto-generated method stub
stage.setScene(scene2);
stage.setHeight(1000);
stage.setWidth(1000);
}
});
stage.setScene(scene1);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}

据我了解上面发布的问题。我认为舞台足够好,可以根据听众设置首选的高度和宽度,获取更新的窗口大小请求。但它有一些限制,如果你最大化或最小化javaFX屏幕并将尝试导航到其他屏幕然后其他屏幕将具有相同的窗口大小但场景内容将扭曲到它的默认高度和宽度,例如,登录和javafx中的家庭场景(所有场景都用fxml进行处理)。 Login.fxml由其控制器初始化。正如您所提到的那样,场景在构造函数中初始化,因此它必须是相关fxml的控制器(截至目前FXML与控制器紧密耦合)。您将在构造函数本身中设置场景大小(高度和宽度)。
1。)LoginController for login.fxml
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import java.io.IOException;
class LoginController {
private Stage stage;
private Scene scene;
private Parent parent;
@FXML
private Button gotoHomeButton;
public LoginController() throws Exception {
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/fxml/login.fxml"));
fxmlLoader.setController(this);
try {
parent = (Parent) fxmlLoader.load();
// set height and width here for this login scene
scene = new Scene(parent, 1000, 800);
} catch (IOException ex) {
System.out.println("Error displaying login window");
throw new RuntimeException(ex);
}
}
// create a launcher method for this. Here I am going to take like below--
public void launchLoginScene(Stage stage) {
this.stage = stage;
stage.setScene(scene);
stage.setResizable(true);
stage.widthProperty().addListener(new ChangeListener<Number>() {
@Override
public void changed(ObservableValue<? extends Number> observableValue, Number number, Number number2) {
setCurrentWidthToStage(number2);
}
});
stage.heightProperty().addListener(new ChangeListener<Number>() {
@Override
public void changed(ObservableValue<? extends Number> observableValue, Number number, Number number2) {
setCurrentHeightToStage(number2);
}
});
//Don't forget to add below code in every controller
stage.hide();
stage.show();
}
@FXML
public void authenticateUser(ActionEvent actionEvent) {
// write your logic to authenticate user
//
new HomeController().displayHomeScreen(stage);
}
private void setCurrentWidthToStage(Number number2) {
stage.setWidth((double) number2);
}
private void setCurrentHeightToStage(Number number2) {
stage.setHeight((double) number2);
}
}
2.。)HomeController相同 -
public class HomeController {
private Parent parent;
private Stage stage;
private Scene scene;
public HomeController (){
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/fxml/home.fxml"));
fxmlLoader.setController(this);
try {
parent = (Parent) fxmlLoader.load();
// set height and width here for this home scene
scene = new Scene(parent, 1000, 800);
} catch (IOException e) {
// manage the exception
}
}
public void displayHomeScreen(Stage stage){
this.stage = stage;
stage.setScene(scene);
// Must write
stage.hide()
stage.show();
}
}
3。)主要课程
import javafx.application.Application;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
new LoginController().launchLoginScene(primaryStage);
}
public static void main(String[] args) {
launch(args);
}
}
尝试将Stage.show()放在每个控制器中的Stage.show()之前。我希望这会帮助你。

我知道这是一个老话题,但是这个(bug?)仍然存在于Java7u75中。
我遇到了同样的问题......上面shambhu提供的解决方案确实有效,但会产生明显的“窗口切换”效果:
classes: "hidden-xs", labelClasses: "hidden-xs"
我发现以下代码解决了问题(获得“刷新”阶段)而没有任何可见效果:
stage.hide();
stage.show();
