Question

我正在尝试用Java创建一个甲板游戏。我想一个接一个地显示四张牌，然后等待几秒钟再显示另外四张牌，依此类推。我在下面创建了代码，但卡号＃4根本没有显示。例如，它显示3张卡然后等待几秒钟，然后显示其他3张卡。

代码的第一部分：

class ButtonListener implements ActionListener {

    public void actionPerformed(ActionEvent e) {
        int hideCount = 0;
        addFirstCenterLabel();
        addSecondCenterLabel();
        addThirdCenterLabel();
        addForthCenterLabel();
        for (int i = 0 ; i < 32 ; i++) {
            if (button[i] == e.getSource()) {
                if (button[i] == button[0] || button[i] == button[1] ||
                    button[i] == button[2] || button[i] == button[3] ||
                    button[i] == button[4] || button[i] == button[20] ||
                    button[i] == button[21] || button[i] == button[22]) {
                    southPanelbutton.remove(button[i]);
                    southPanelbutton.validate();
                    southPanelbutton.repaint();

                    labelThirdCenter.setIcon(showCard[i]);

                }
            }
            if (button[i] == e.getSource()) {
                if (button[i] == button[5] || button[i] == button[6] ||
                    button[i] == button[7] || button[i] == button[8] ||
                    button[i] == button[9] || button[i] == button[23] ||
                    button[i] == button[24] || button[i] == button[25]) {
                    eastPanelbutton.remove(button[i]);
                    eastPanelbutton.validate();
                    eastPanelbutton.repaint();

                    labelForthCenter.setIcon(showCard[i]);
                }
            }
            if (button[i] == e.getSource()) {
                if (button[i] == button[10] || button[i] == button[11] ||
                    button[i] == button[12] || button[i] == button[13] ||
                    button[i] == button[14] || button[i] == button[26] ||
                    button[i] == button[27] || button[i] == button[28]) {
                    northPanelbutton.remove(button[i]);
                    northPanelbutton.validate();
                    northPanelbutton.repaint();

                    labelSecondCenter.setIcon(showCard[i]);
                }
            }
            if (button[i] == e.getSource()) {
                if (button[i] == button[15] || button[i] == button[16] ||
                    button[i] == button[17] || button[i] == button[18] ||
                    button[i] == button[19] || button[i] == button[29] ||
                    button[i] == button[30] || button[i] == button[31]) {
                    westPanelbutton.remove(button[i]);
                    westPanelbutton.validate();
                    westPanelbutton.repaint();
                    labelFirstCenter.setIcon(showCard[i]);
                    hideCount++;
                }
            }
            if (button[i] == e.getSource()) {
                if (button[i] == button[15] || button[i] == button[16] ||
                    button[i] == button[17] || button[i] == button[18] ||
                    button[i] == button[19] || button[i] == button[29] ||
                    button[i] == button[30] || button[i] == button[31]) {
                    hideCount++;
                    timeDelay();
                    if (hideCount == 1 || hideCount == 2 || hideCount == 3 ||
                        hideCount == 4 || hideCount == 5 || hideCount == 6 ||
                        hideCount == 7 || hideCount == 8) {
                        hideCards();
                    }
                }
            }
        }
    }
}

代码的第二部分：

public void addFirstCenterLabel() {
    // centerPanelLabel.add(labelFirstCenter);
    // centerPanel.add(centerPanelLabel);
    // down table
    centerPanel.setLayout(new GridBagLayout());
    c.gridx = 1;
    c.gridy = 3;
    centerPanel.add(labelThirdCenter, c);
    add(centerPanel);
}

public void addSecondCenterLabel() {
    // centerPanelLabel.add(labelSecondCenter);
    // centerPanel.add(centerPanelLabel);
    // right table
    c.gridx = 2;
    c.gridy = 1;
    centerPanel.add(labelForthCenter, c);
    add(centerPanel);
}

public void addThirdCenterLabel() {
    // centerPanelLabel.add(labelThirdCenter);
    // centerPanel.add(centerPanelLabel);
    // top label
    c.gridx = 1;
    c.gridy = 0;
    centerPanel.add(labelSecondCenter, c);
    add(centerPanel);
}

public void addForthCenterLabel() {
    // centerPanelLabel.add(labelForthCenter);
    // centerPanel.add(centerPanelLabel);

    // left table
    c.gridx = 0;
    c.gridy = 1;
    centerPanel.add(labelFirstCenter, c);
    add(centerPanel);

    // to count the round of the game. each four cards count as 1.
    for (int j = 0 ; j <= 7 ; j++) {
        if (rounds[j] == 0) {
            rounds[j] = 1;
            break;
        }
    }
}

代码的第三部分：

public void hideCards() {
    for (int j = 0 ; j <= 7 ; j++) {
        // System.out.println(rounds[j]);
        // if the round ==1, make the four cards unvisible
        if (rounds[j] == 1) {
            labelThirdCenter.setIcon(emptyCard[0]);
            labelForthCenter.setIcon(emptyCard[0]);
            labelSecondCenter.setIcon(emptyCard[0]);
            labelFirstCenter.setIcon(emptyCard[0]);
        }
    }
}

public void timeDelay() {
    try {
        Thread.sleep(2500); // one second
    }
    catch (InterruptedException e) {
        throw new RuntimeException("Don't know how to handle this", e);
    }
}

Answer 1

在UI线程上调用Thread.sleep不是一个好主意。它将在线程休眠时禁用所有UI更新。

我没有详细检查，但似乎卡4的图纸是预定的，但是当线程进入睡眠状态时尚未执行。
