如何存储和删除各个对象的警报
How to store and delete alarms for respective object
我有一个小问题，如果你能帮助我，我将不胜感激。我有一个应用程序，例如客户药物的本地数据库，在添加药丸时，他可以在需要服用该特定药丸时添加提醒。他只能设置一个小时（临时）和 select 一周中的某些天。因此，该应用程序会在每天的特定时间发出警报，我的应用程序会以这种方式发出许多警报，我认为这不是最好的方法，但是是的，这就是我的方法。如果这是更好的方法，请帮助我。但我现在的主要问题是如何存储未决意图，以便在客户想要删除药物时禁用相应药丸的警报。

非常感谢您的关注，希望您至少能帮我一点忙。祝你有个美好的一天！
这段代码有问题。首先，您说您要设置多个警报。为了让您设置多个闹钟，您需要保证每个 PendingIntent 都是唯一的。你这样做：
Intent intent = new Intent(getApplicationContext(), NotificationService.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),
Calendar.getInstance().get(Calendar.MILLISECOND), intent,
PendingIntent.FLAG_UPDATE_CURRENT);
除了 requestId 参数（第二个参数）外，您的所有警报都使用与 PendingIntent 相同的参数，您使用的是 Calendar.MILLISECOND 字段。这 不是唯一的 。 Calendar.MILLISECOND 将为您提供一个介于 0 和 999 之间的数字，表示特定时间戳的第二 内的 毫秒。这不能保证是唯一的。可能是也可能不是。
你问如何存储PendingIntent以便取消闹钟。实际上，您不需要存储 PendingIntent。您可以重新创建 PendingIntent 以取消警报。只需与最初设置闹钟时完全相同的操作即可。像这样：
Intent intent = new Intent(getApplicationContext(), NotificationService.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),
Calendar.getInstance().get(Calendar.MILLISECOND), intent,
PendingIntent.FLAG_UPDATE_CURRENT);
// Cancel the alarm
AlarmManager alarmManager = (AlarmManager)getApplicationContext()
.getSystemService(ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
// Now cancel the PendingIntent also (just to be sure)
pendingIntent.cancel();
这里的技巧是 PendingIntent.getBroadcast() 调用的 requestId（第二个参数）需要与您设置警报时使用的 requestId 完全匹配。所以你必须存储它。由于时间的毫秒部分不是唯一的，因此您需要找到一个更好的唯一数字用作 requestId。如果您每天只设置一个闹钟，您可以使用天数作为 requestId，例如 Calendar.DAY_OF_WEEK，或者您可以使用其他一些唯一 ID。设置和取消闹钟时使用相同的值。
