Question

我正在尝试创建配对游戏。我创建了2个JPanels：首先是游戏地图（100个按钮），第二个是统计数据。问题是我在左侧图片上部署了计时器和计数器，但我希望在右图上（我在油漆中编辑它）。我应该使用什么布局？我尝试了很多解决方案，但没有任何对我有用。另外，如果我设置空管理器JPanel dissapear

public class PairGame extends JFrame implements ActionListener{

JLabel counterLabel, timerLabel;
JMenuBar menuBar;
JMenu file, help;
JMenuItem fileNew, fileExit, helpAbout;
JPanel gamePanel, statisticsPanel;
JToggleButton buttons[];

ArrayList <Integer> values;

int temp=0, counter=0;

void createMenuBar()
{        
    file = new JMenu("File");
        fileNew = new JMenuItem("New");
        fileNew.addActionListener(this);
        fileNew.setAccelerator(KeyStroke.getKeyStroke("ctrl N"));
        fileExit = new JMenuItem("Exit");
        fileExit.addActionListener(this);
        fileExit.setAccelerator(KeyStroke.getKeyStroke("ctrl Q"));
        file.add(fileNew);
        file.add(fileExit);
        file.setMnemonic('f');

    help = new JMenu("Help");
        helpAbout = new JMenuItem("About");
        helpAbout.addActionListener(this);
        helpAbout.setAccelerator(KeyStroke.getKeyStroke("ctrl H"));
        help.add(helpAbout);
        help.setMnemonic('h');

    menuBar = new JMenuBar();
        menuBar.add(file);
        menuBar.add(help);
        setJMenuBar(menuBar);
}

public void createGameMap()
{     
    gamePanel = new JPanel(new GridLayout(10,10));

    values = new ArrayList<Integer>();
    for(int i=1; i<=50; i++)
        values.add(i);
    for(int i=51; i<=100; i++)
        values.add(i-50);

    Collections.shuffle(values);      

    buttons = new JToggleButton[100];
    for(int i=0; i<100; i++)
    {
        buttons[i] = new JToggleButton(""+(i+1));
        buttons[i].setName(String.valueOf(values.toArray()[i]));
        buttons[i].addActionListener(this);
        gamePanel.add(buttons[i]);
    }

    gamePanel.setBounds(0,0,550,400);
    add(gamePanel);
}

public void createStatisticsPanel()
{
    statisticsPanel = new JPanel();
    counterLabel = new JLabel("Counter: "+counter);
    timerLabel = new JLabel("Timer: ");
    statisticsPanel.add(counterLabel); 
    statisticsPanel.add(timerLabel);
    statisticsPanel.setBounds(0,410,540,400);
    add(statisticsPanel);
}


PairGame()
{
    setTitle("Pair Game");
    setSize(565,600);
    setLocation(400,100);        
    setLayout(null);
    setDefaultCloseOperation(EXIT_ON_CLOSE);       

    createMenuBar();
    createGameMap();   
    createStatisticsPanel();

    setVisible(true);
}

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

Answer 1

有各种不同的布局管理器允许您将对象“关注”到彼此。

如果你看一下来自Oracle的BoxLayout的第二个例子......惊喜：该面板显示“两个元素”，上面一个是左对齐标签。可能正是你想要的。

可替换地;正确GridLayout的第一个示例也有对齐标签。

我的回答的目的不仅是为了演示一个可能的解决方案，使用布局管理器作为GhostCat建议，而且还展示了MCVE的想法，以便更容易帮助并获得帮助。

import java.awt.GridLayout;

public class PairGame extends JFrame {

    //removed fields to keep code as short as possible
    JLabel counterLabel, timerLabel;
    JPanel gamePanel, statisticsPanel;

    //menu bar removed to keep the code as short as possible
    //void createMenuBar()

    public void createGameMap()
    {
        //simplify as much as possible
        gamePanel = new JPanel(new GridLayout(1,1));

        JToggleButton button = new JToggleButton("1");
        gamePanel.add(button);

        //use layout managers is preferred practice over setting bounds
        add(gamePanel, BorderLayout.CENTER);
    }

    public void createStatisticsPanel()
    {
        counterLabel = new JLabel("Counter: ");
        timerLabel = new JLabel("Timer: ");

        statisticsPanel = new JPanel();

        //use layout managers is preferred practice over setting bounds
        //the layout you want can be achieved with various managers
        //such as BorderLayout, BoxLayout, Gridlayout

        statisticsPanel.add(counterLabel, BorderLayout.NORTH);
        statisticsPanel.add(timerLabel, BorderLayout.SOUTH);

        //to test box layout REPLACE the 3 statements above with  
        //Implementation of BoxLayout 
        //BoxLayout boxLayout = new BoxLayout(statisticsPanel,BoxLayout.Y_AXIS);
        //statisticsPanel.setLayout(boxLayout);
