在android中设置一周中的重复天数警报
有人能给出一个很好的逻辑来设定一周中重复几天的警报吗？我每周都会用
alarmCalendar.set(Calendar.HOUR, AlarmHrsInInt);
alarmCalendar.set(Calendar.MINUTE, AlarmMinsInInt);
alarmCalendar.set(Calendar.SECOND, 0);
alarmCalendar.set(Calendar.AM_PM, amorpm);
Long alarmTime = alarmCalendar.getTimeInMillis();
Intent intent = new Intent(Alarm.this, AlarmReciever.class);
intent.putExtra("keyValue", key);
PendingIntent pi = PendingIntent.getBroadcast(Alarm.this, key, intent, PendingIntent.FLAG_UPDATE_CURRENT);
am.setRepeating(AlarmManager.RTC_WAKEUP, alarmTime, 7*1440*60000 , pi); 报警触发准时，7天后自动触发。
但我的要求是，我想选择的日子，而不是仅仅7天。
就像每周一，星期二，星期四上午9点一样-警报应该会自动触发。我该如何在setRepeating中这样做呢？
有人能帮我解决这个问题吗？
谢谢!

这些问题谈论的都是你想要的东西。这些答案将有帮助：
您只需要指定开始的日期，然后每7天重复一次。在对给定问题的回答中，有几种具体的方法：

你在评论中说
如何在triggerAtMillis中设置setRepeating部件。比方说今天是星期二，我选择每周星期一，星期三，星期五。-我星期三要放什么？
我所理解的是，如果今天是星期二，如何设置警报，让我们说星期三重复，对吗？首先，是的，您可以使用多个id来分别设置每天的警报。
然后，可以将alarmCalendar.set(Calendar.DAY_OF_WEEK, week);行添加到现有代码中。根据周一天(从1-7)，它重复了那一天。您可以将它作为参数传递到函数中。比如：
setAlarm(2); //set the alarm for this day of the week
public void setAlarm(int dayOfWeek) {
// Add this day of the week line to your existing code
alarmCalendar.set(Calendar.DAY_OF_WEEK, dayOfWeek);
alarmCalendar.set(Calendar.HOUR, AlarmHrsInInt);
alarmCalendar.set(Calendar.MINUTE, AlarmMinsInInt);
alarmCalendar.set(Calendar.SECOND, 0);
alarmCalendar.set(Calendar.AM_PM, amorpm);
Long alarmTime = alarmCalendar.getTimeInMillis();
//Also change the time to 24 hours.
am.setRepeating(AlarmManager.RTC_WAKEUP, alarmTime, 24 * 60 * 60 * 1000 , pi);
}我从上面的一个问题中拿出了这个例子。希望现在更清楚。

若要设置一周的重复警报，请使用下面的代码。希望这会有帮助。
Calendar calender= Calendar.getInstance();
calender.set(Calendar.DAY_OF_WEEK, weekNo); //here pass week number
calender.set(Calendar.HOUR_OF_DAY, hour); //pass hour which you have select
calender.set(Calendar.MINUTE, min); //pass min which you have select
calender.set(Calendar.SECOND, 0);
calender.set(Calendar.MILLISECOND, 0);
Calendar now = Calendar.getInstance();
now.set(Calendar.SECOND, 0);
now.set(Calendar.MILLISECOND, 0);
if (calender.before(now)) { //this condition is used for future reminder that means your reminder not fire for past time
calender.add(Calendar.DATE, 7);
}
final int _id = (int) System.currentTimeMillis(); //this id is used to set multiple alarms
Intent intent = new Intent(activity, YourServiceClass.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(activity, _id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calender.getTimeInMillis(), 7 * 24 * 60 * 60 * 1000, pendingIntent);Stack Overflow用户

setalarm(5);
} else if (Friday.isChecked()) {
setalarm(6);
} else if (Saturday.isChecked()) {

} else if (Sunday.isChecked()) {

}
public void setalarm(int weekno) {
cal.set(Calendar.DAY_OF_WEEK, weekno);
cal.set(Calendar.MINUTE, min);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(), 1 * 60 * 60 * 1000, pendingIntent);
