如何在Android中使用警报管理器设置多个警报 [英] How to set multiple alarms using alarm manager in android

问题描述

我正在构建一个警报应用程序。我已经成功实现了基本的警报功能。

I'm building an alarm application. I have successfully implemented basic alarm functions.

Calendar calendar = Calendar.getInstance();
calendar.set(calendar.HOUR_OF_DAY, sHour);
calendar.set(calendar.MINUTE, sMin);
calendar.set(calendar.SECOND, 0);
calendar.set(calendar.MILLISECOND, 0);
long sdl = calendar.getTimeInMillis();

Intent intent = new Intent(AlarmList.this, AlarmReceiver.class);
PendingIntent sender = PendingIntent.getBroadcast(AlarmList.this, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager ALARM1 = (AlarmManager)getSystemService(ALARM_SERVICE);
ALARM1.set(AlarmManager.RTC_WAKEUP, sdl, sender);

在我的应用程序中，用户可以选择天数（星期日，星期一... ）每周重复一次警报。
我正在尝试创建多个警报以每周重复一次，但不知道如何执行。
是否可以使用（重复）间隔创建它？还是应该创建多个警报管理器？

In my application, user can select days (sunday,monday...) to repeat the alarm weekly. I'm trying to create multiple alarms to repeat weekly but don't know how to do it. Can I create it using (repeat) interval or should I create multiple alarm managers?

推荐答案

您需要使用待定意向的个不同的广播ID。像
这样的东西：

You need to use different Broadcast id's for the pending intents. Something like this:

Intent intent = new Intent(load.this, AlarmReceiver.class);
final int id = (int) System.currentTimeMillis();
PendingIntent appIntent = PendingIntent.getBroadcast(this, id, intent, PendingIntent.FLAG_ONE_SHOT);

使用系统时间应该是您触发的每个未决
意图的唯一标识符。

Using the system time should be a unique identifier for every pending intent you fire.
