我正在尝试用字母表中每个字母的按钮创建一个刽子手游戏。我使用绝对定位和多个动作滑块很难做到这一点。有什么方法可以用for循环做到这两点吗？
另外，如何使用多态数组实现我的刽子手？我现在拥有它的方式，我将为每个肢体使用if语句。我想在他自己的面板上创建这个人，然后在猜测时使用失败时将每个肢体的可见性设置为真。
感谢任何帮助。

答案 0 :(得分：1)
您可以尝试这样的事情：
// create a JPanel to hold the buttons that uses a GridLayout with 3 rows
JPanel buttonPanel = new JPanel(new GridLayout(3, ));
for (int i = 0; i < 26; ++i)
{
wButton = new JButton('A' + i);
buttonPanel.add(wButton);
// wButton.setBounds(30 + i * 50, 550, 50, 29); // avoid this
wButton.addActionListener(
new ActionListener()
{
@Override
public void actionPerformed(ActionEvent event)
{
}
}
);
}
// here add the buttonPanel to the main GUI
要解决这个问题：
1）我们使用for循环来通过字母表中的26个字母。
2）我们创建一个标题为字母的按钮。因为字符实际上只是整数，所以在A＆＃39; A＆＃39;中添加1。收益率＆＃39; B＆＃39;所以，我们可以使用A＆＃39; + i作为一个小技巧。此外，您可以使用所有字母的数组，并执行类似letter [i]的操作。
3）避免使用setBounds，而是使用布局管理器更轻松，更简单地放置和调整按钮大小。
免责声明：我还没有对此进行过测试，这只是让你走上正轨的好方法。
答案 1 :(得分：1)
使用布局管理器管理按钮的大小调整，不要使用setBounds()。您目前创建了一个但未设置它，因此未使用它。
layout = new FlowLayout();
setLayout(null); // Why set null and not layout
正确设置布局，然后您可以在for循环中使用char，如
for(char c = 'A'; c <= 'Z'; c++)
{
JButton button = new JButton("" + c);
// add action listener also
add(button); // adding will add it using the layout manager
}
您可以详细了解layout managers here。

letterButtonPanel.setBorder(BorderFactory.createTitledBorder("Letters"));
ButtonListener buttonListener = new ButtonListener();
for (char c = 'A'; c <= 'Z'; c++) {
String text = String.valueOf(c);
JButton button = new JButton(text);
button.addActionListener(buttonListener);
letterButtons.add(button); // add JButton to List<JButton>
letterButtonPanel.add(button); // and add to GridLayout-using JPanel
}
// JPanel to hold non-letter JButtons
JPanel specialBtnsPanel = new JPanel(new GridLayout(1, 0, 3, 3));
specialBtnsPanel.add(new JButton(new ResetAction("Reset", KeyEvent.VK_R)));
specialBtnsPanel.add(new JButton(new ExitAction("Exit", KeyEvent.VK_X)));
// JPanel to hold non-drawing JPanels. It uses BoxLayout
JPanel bottomPanel = new JPanel();
bottomPanel.setLayout(new BoxLayout(bottomPanel, BoxLayout.PAGE_AXIS));
bottomPanel.add(letterButtonPanel);
bottomPanel.add(specialBtnsPanel);
// set layout and border of main JPanel and add other JPanels to it
setBorder(BorderFactory.createEmptyBorder(3, 3, 3, 3));
setLayout(new BorderLayout(3, 3));
add(drawingPanel, BorderLayout.CENTER);
