Question

我正在创建一个应用程序，有两个类 - 两个框架。用户打开应用程序并查看包含3 Jbuttons的框架，这意味着不同的语言。点击一个特定按钮时，应该打开下一帧，所有标签都选择所选语言。问题是，无论我做什么，它只用一种语言打开。我试过很多解决方案，但它永远不会奏效我会很感激一些代码，这会有所帮助。

头等舱，带有起始帧：

import java.awt.*;
import java.awt.event.*;
import java.util.Locale;
import java.util.ResourceBundle;
import javax.swing.*;
public class StartFrame extends JFrame {
public StartFrame() {
    setSize(480,360);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    panelFlags = new JPanel();

    this.add(panelFlags);
    panelFlags.setBackground(Color.white);
    buttonFlagPl= new JButton(new ImageIcon(((new ImageIcon("x.png")).getImage()).getScaledInstance(100, 75, java.awt.Image.SCALE_SMOOTH)));
    buttonFlagEn = new JButton(new ImageIcon(((new ImageIcon("y.jpg")).getImage()).getScaledInstance(100, 75, java.awt.Image.SCALE_SMOOTH)));
    buttonFlagDe = new JButton(new ImageIcon(((new ImageIcon("z.jpg")).getImage()).getScaledInstance(100, 75, java.awt.Image.SCALE_SMOOTH)));
    buttonFlagPl.setPreferredSize(new Dimension(100, 75));
    buttonFlagEn.setPreferredSize(new Dimension(100, 75));
    buttonFlagDe.setPreferredSize(new Dimension(100, 75));

    panelFlags.add(buttonFlagPl);
    panelFlags.add(buttonFlagEn);
    panelFlags.add(buttonFlagDe);


    buttonFlagPl.addActionListener (new ActionListener(){
        public void actionPerformed(ActionEvent e) {
            MainFrame mainFramePl= new MainFrame();
            mainFramePl.setVisible(true);
            mainFramePl.setLocationRelativeTo(null);
            mainFramePl.resourceBundle = ResourceBundle.getBundle("labels_pl", new Locale ("pl"));
            dispose();  
        }           
    });

    buttonFlagEn.addActionListener (new ActionListener(){
        public void actionPerformed(ActionEvent e) {
            MainFrame mainFrameEn = new MainFrame();
            mainFrameEn.setVisible(true);
            mainFrameEn.setLocationRelativeTo(null);
            mainFrameEn.resourceBundle = ResourceBundle.getBundle("labels_en",new Locale ("en"));
            dispose();  
        }           
    });

    buttonFlagDe.addActionListener (new ActionListener(){
        public void actionPerformed(ActionEvent e) {
            MainFrame mainFrameDe = new MainFrame();
            mainFrameDe.setVisible(true);
            mainFrameDe.setLocationRelativeTo(null);
            mainFrameDe.resourceBundle =  ResourceBundle.getBundle("labels_de",new Locale ("de"));
            dispose();  
        }           
    });
}

JPanel panelFlags;
JButton buttonFlagPl;
JButton buttonFlagEn; 
JButton buttonFlagDe; 

public static void main(String[] args) {
    StartFrame startFrame = new StartFrame();
    startFrame.setVisible(true);
    startFrame.setLocationRelativeTo(null);     
}
}

这是主框架的部分：

public class MainFrame extends JFrame {
public MainFrame(){
    super();
    setSize(1000,640);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
mainPanel = new JPanel(new FlowLayout(500,200,5));
    mainPanelColor = new Color (200,200,230);
    mainPanel.setBackground(mainPanelColor);
    buttonBackToChooseLanguage = new JButton();
 buttonBackToChooseLanguage.setText((resourceBundle).getString("button.back"));

（...）

ResourceBundle resourceBundle = ResourceBundle.getBundle("labels");

public static void main(String[] args) {
    MainFrame window = new MainFrame();
    window.setLocationRelativeTo(null);
    window.setVisible(true);

}

我故意错过了其余的代码。问题是，无论我放入"ResourceBundle resourceBundle = ResourceBundle.getBundle("labels");"，它总是为所有按钮提供同一种语言，所以我认为，行"mainFramePl.resourceBundle = ResourceBundle.getBundle("labels_pl", new Locale ("pl"));"不起作用。

Answer 1

在将buttonBackToChooseLanguage设置为新值之前，您已在MainFrame构造函数中设置resourceBundle的标签 - 而构造函数正在运行时始终设置ResourceBundle.getBundle("labels")到MainFrame。

所以MainFrame(ResourceBundle bundle) { resourceBundle = bundle; // set up the frame ... // set labels using resourceBundle }看起来像是：

buttonFlagDe.addActionListener (new ActionListener(){
    public void actionPerformed(ActionEvent e) {
        MainFrame mainFrameDe = new MainFrame(ResourceBundle.getBundle("labels_de",new Locale ("de")));
        mainFrameDe.setVisible(true);
        mainFrameDe.setLocationRelativeTo(null);
        dispose();  
    }           
});

你的actionListeners看起来像：
