我正在尝试设置一个程序,使用户在单击下一个和上一个按钮时可以显示过渡。当按下下一步时,摆动计时器应触发并开始动画。过渡时,应该有一个标志指出它处于过渡期间。 Swing计时器应每十分之一秒触发一次,并且基本上应持续1秒钟。
public class guiCreation {
static Timer timer;
static boolean flag = false;
private static void guiInterface() {
next.addActionListener(new ActionListener(){
timer = new Timer(1000, this);
public void actionPerformed(ActionEvent e){
nextGest();
}
});
//should go to the next tab
previous.addActionListener(new ActionListener(){
//if the list gets to the beginning, disable button
public void actionPerformed(ActionEvent e){
prevGest();
}
});
}
public static void nextGest() {
timer.start();
previous.setEnabled(true);
next.setEnabled(true);
//if the list gets to the end, disable button
if (cardLayout.isNextCardAvailable()) {
status.setText(" Next button has been clicked");
//System.out.println("This is the" + size);
cardLayout.next(cardPanel);
next.setEnabled(cardLayout.isNextCardAvailable());
}
}
public static void prevGest() {
if (cardLayout.isPreviousCardAvailable()) {
timer.start();
next.setEnabled(true);
previous.setEnabled(true);
status.setText(" Previous button has been clicked");
cardLayout.previous(cardPanel);
previous.setEnabled(cardLayout.isPreviousCardAvailable());
}
}
}
[此:"The Swing timer should fire once every tenth of a second ..."
-与此不同:timer = new Timer(1000, this);
您的计时器每秒触发一次,而不是每秒十分之一。
相反,您应该:
new Timer(100, ...)
,每10秒触发一次((Timer) e.getSource()).stop();
停止计时器.isRunning()
。例如if (timer != null && timer.isRunning()) {
-动画就在继续。
