AlarmManager使用

一.獲取AlarmManager

AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

二.設置鬧鐘

1.組建一個啓動時間

Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
cal.set(Calendar.HOUR_OF_DAY, item.hour);
cal.set(Calendar.MINUTE, item.min);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
cal.add(Calendar.DAY_OF_MONTH, 0);//參數爲0使 設置當天 爲1時設置第二天 ...

2.要啓動的服務or...

Intent intent = new Intent(this, SomeService.class);
demuteIntent.putExtra(KEY, "");
//如果要傳遞多個PendingIntent id一定要不同
PendingIntent pendingIntent = PendingIntent.getService(this,
					id, demuteIntent, 0);

3.把PendingIntent加入

alarm.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
					pendingIntent);
