如何停止2個javax.swing.Timer
[英]how to stop 2 javax.swing.Timer
問題描述
我在java中創建了一個提醒程序，該程序將根據用戶輸入調用另一個3 JFrame，我成功運行了3個JFrame，但是當我想禁用/關閉計時器時，只有第一個計時器（SHORT BREAK）關閉了，其他兩個仍在運行（）
1.這是處理每個JFrame的代碼，如您所見，我將3種不同的方法調用3種不同的JFrame，但是當我鍵入timer.close（）時，只有第一個方法關閉了；
private void callShortBreak(){
System.out.println("Start SHORT BREAK...");
timer = new Timer(systemTime.getShortBreakTime(), new ActionListener() {
public void actionPerformed(ActionEvent e) {
/*if(chckbxTakeAShort.isSelected()){*/
/*Notification_Short_Break notif_short = new Notification_Short_Break();
notif_short.runNotification();*/
System.out.println("SHORT BREAK-"+loopShortBreak+" : "+ systemTime.getShortBreakTime() +" milisecond");
loopShortBreak++;
/*} */
}
});
timer.setRepeats(true);
timer.start();
}
private void callLongBreak(){
System.out.println("Start LONG BREAK...");
timer = new Timer(systemTime.getLongBreakTime(), new ActionListener() {
public void actionPerformed(ActionEvent e) {
/*if(chckbxTakeALong.isSelected()){*/
/* Notification_Long_Break notif_long = new Notification_Long_Break();
notif_long.runNotification(systemTime.getLongBreakDuration());*/
System.out.println("LONG BREAK-"+loopLongBreak+" : "+ systemTime.getLongBreakTime() +" milisecond");
loopLongBreak++;
/*} */
}
});
timer.setRepeats(true);
timer.start();
}
private void callLongBreakNotify(){
System.out.println("Start Notification LONG BREAK");
timer = new Timer(systemTime.getLongBreakTime()-systemTime.getLongBreakNotifyTime(), new ActionListener() {
public void actionPerformed(ActionEvent e) {
/*if(chckbxNotifiyLongBreak.isSelected()){*/
/*Notification_Before_Long_Break notif_before_long = new Notification_Before_Long_Break();
notif_before_long.runNotification();*/
System.out.println("NOTIFICATION LONG BREAK-"+loopLongBreakNotification+" : "+ (systemTime.getLongBreakTime()-systemTime.getLongBreakNotifyTime()) +" milisecond");
loopLongBreakNotification++;
/*}*/
}
});
timer.setRepeats(true);
timer.start();
}
2.這是調用上面代碼的代碼
public void timeSettings(){
if(chckbxTakeALong.isSelected()){
systemTime.setLongBreakTime(cbLongBreak.getSelectedIndex());
systemTime.setLongBreakDuration(cbLongBreakDuration.getSelectedIndex());
callLongBreak();
}
if(chckbxNotifiyLongBreak.isSelected() && chckbxTakeALong.isSelected()){
systemTime.setLongBreakNotifyTime(cbNotifyLongBreak.getSelectedIndex());
callLongBreakNotify();
}
if(chckbxTakeAShort.isSelected()){
systemTime.setShortBreakTime(cbShortBreak.getSelectedIndex());
callShortBreak();
}
}
3.這是關閉計時器的按鈕
final JButton btnSaveAndClose = new JButton("Save and Close");
btnSaveAndClose.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
try{
System.out.println("Stop all Timer.....");
timer.stop();
}catch(Exception ex){
}
settings_Page.timeSettings();
saveCurrentSettings();
settings_Page.dispose();
}
});
btnSaveAndClose.setBounds(98, 331, 138, 23);
getContentPane().add(btnSaveAndClose);
4.這是完整的Settings_Page類

每個計時器需要3個字段（而不僅僅是一個計時器），因此當您創建第二個計時器時，對第一個計時器的引用會丟失。
定義例如
Timer shortBreakTimer;
Timer longBreakTimer;
Timer anotherBreakTimer;
然后在關閉時停止所有3個實例
