我为此感到挣扎。在Google上进行研究之后,我创建了以下计时器例程,该例程在调用时效果很好
// play move method
public static void playMove() {
int delay = 1200; // delay for 1 sec.
int period = 1200; // repeat every sec.
final Timer timer = new Timer();
timer.schedule(new TimerTask() {
private int count = history.getGameIndex();
public void run() {
count++;
if (count >= history.getTotalMoves() + 1) {
timer.cancel();
timer.purge();
return;
}
history.next();
}
}, delay, period);
}
但是,问题在于我无法弄清楚如何将这段代码集成到JToggleButton中,这是它的正确位置,因此当我单击播放时它会移动,而单击停止时该例程会停止(或暂停)。这是我的JToggleButton代码:
ImageIcon playIcon = new ImageIcon(
JBoard.class.getResource("/images/menu/play.png"));
btnPlayMove = new JToggleButton(playIcon);
btnPlayMove.setToolTipText("Play");
btnPlayMove.setContentAreaFilled(true);
btnPlayMove.setMargin(new Insets(2, 2, 2, 2));
btnPlayMove.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent ie) {
if (isConnected()) {
showMessage("Engine disabled during network play...");
return;
} else if (btnPlayMove.isSelected()) {
// play
playMove();
ImageIcon playIcon = new ImageIcon(JBoard.class
.getResource("/images/menu/play.png"));
btnPlayMove.setIcon(playIcon);
} else {
// stop
ImageIcon stop = new ImageIcon(JBoard.class
.getResource("/images/menu/stop.png"));
btnPlayMove.setIcon(stop);
}
}
});
buttonPanel.add(btnPlayMove);
我是Java的新手,如果有人可以提供帮助,那就太好了
最佳答案
您可以利用javax.swing.Timer
Timer timer = new Timer(1200, new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
count++;
if (count >= history.getTotalMoves() + 1) {
timer.cancel();
timer.purge();
return;
}
history.next();
}
});
timer.setRepeats(true);
timer.setCoalesce(true);
timer.setInitialDelay(1200);
然后,在按钮代码中,您只需调用
timer.start()
或timer.stop()
