JavaSwing鍵盤格式不正確

我目前正在為一個小型游戲專案制作 GUI，但我在鍵盤布局方面遇到了問題，特別是主行和底行。我完全錯過了查看我的代碼，但我有這段代碼：

        home = new JButton[homeRow.length];
        JPanel homekeys = new JPanel(new GridLayout(1, homeRow.length));
        for(int i = 0; i < homeRow.length; i  )
        {
            JButton homesize = new JButton(homeRow[i]);
            homesize.setSize(50, 50);
            home[i] = homesize;
            keyboard.add(home[i]);
        }
        keyboard.add(homekeys);

        bottom = new JButton[bottomRow.length];
        JPanel bottomkeys = new JPanel(new GridLayout(1, bottomRow.length));
        for(int i = 0; i < bottomRow.length; i  )
        {
            JButton bottomsize = new JButton(bottomRow[i]);
            bottomsize.setSize(50, 50);
            bottom[i] = bottomsize;
            keyboard.add(bottom[i]);
        }
        keyboard.add(topkeys);

keyboard.add(topkeys)應該在哪里keyboard.add(bottomkeys)，盡管它正是我想要的格式：

但是當我將其更改為 時keyboard.add(bottomkeys)，出現了一種奇怪的格式：

為什么當我將其更改為 use 時它的格式會奇怪，我將bottomkeys如何解決這個問題？

這是整個代碼：

import javax.swing.*;
import java.awt.*;

public class GameGUI extends JFrame
{
    private final JPanel letters;
    private final JPanel keyboard;
    private final String[] topRow = {"Q", "W", "E", "R", "T", "Y", "U", "I", "O", "P"};
    private final String[] homeRow = {"A", "S", "D", "F", "G", "H", "J", "K", "L"};
    private final String[] bottomRow = {"Enter", "Z", "X", "C", "V", "B", "N", "M", "Backspace"};
    private final JButton[] top, home, bottom; // buttons for rows

    public WordleGUI()
    {
        this.setSize(350,400);
        this.setDefaultCloseOperation(EXIT_ON_CLOSE);

        letters = new JPanel();
        letters.setLayout(new GridLayout(6, 5));

        for(int i = 0; i < 30; i  )
            letters.add(new JTextField());

        keyboard = new JPanel();
        keyboard.setLayout(new GridLayout(3, 1));

        // top row
        top = new JButton[topRow.length];
        JPanel topkeys = new JPanel(new GridLayout(1, topRow.length));
        for(int i = 0; i < topRow.length; i  )
        {
            JButton topsize = new JButton(topRow[i]);
            topsize.setSize(50, 50);
            top[i] = topsize;
            keyboard.add(top[i]);
        }
        keyboard.add(topkeys);

        // home row
        home = new JButton[homeRow.length];
        JPanel homekeys = new JPanel(new GridLayout(1, homeRow.length));
        for(int i = 0; i < homeRow.length; i  )
        {
            JButton homesize = new JButton(homeRow[i]);
            homesize.setSize(50, 50);
            home[i] = homesize;
            keyboard.add(home[i]);
        }
        keyboard.add(homekeys);

        bottom = new JButton[bottomRow.length];
        JPanel bottomkeys = new JPanel(new GridLayout(1, bottomRow.length));
        for(int i = 0; i < bottomRow.length; i  )
        {
            JButton bottomsize = new JButton(bottomRow[i]);
            bottomsize.setSize(50, 50);
            bottom[i] = bottomsize;
            keyboard.add(bottom[i]);
        }
        keyboard.add(bottomkeys); // weird formatting occuring here

        this.getContentPane().add(letters, BorderLayout.NORTH);
        this.getContentPane().add(keyboard, BorderLayout.SOUTH);
        this.setVisible(true);
    }

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

uj5u.com熱心網友回復：

您正在創建三個面板topkeys、homekeys和buttomkeys ，但實際上并沒有按預期使用它們。將按鈕添加到這些而不是鍵盤面板上。
