如何解决3 个不同时间的警报管理器，第二个在第一个触发时触发而不是在指定时间触发ANDROID STUDIO
所以我正在制作出生日期提醒应用程序，对于我制作的每个出生日期，我设置了 3 个闹钟管理器在特定时间触发（我选择我的分钟和小时进行测试），所以我让 weekAlarm 可以在 8:00 和我的dayBeforeAlarm 在 8:01 和我的 onDatealarm 在 8:02，所以 weekAlarm 应该在 8 和 dayBeforeAlarm 应该在 8:01 触发等等......，所以当我制作一个生日时它很好并且它工作得很好但是当我做超过一个 BirthDate 每当第一个 AlarmManager(weekAlarm) 被触发时，AlarmManagers 就会触发，所以如果我有 2 个 BirthDates 然后一次 weekAlarm 触发，立即 dayBeforeAlarm 触发，如果我有 3 个出生日期，那么一次 weekAlarm 触发，立即 dayBeforeAlarm 和 onDatealarm 触发。 请注意，我指定的所有生日都必须是同一日期。我怎样才能让他们在他们选择的时间开火？

解决方法
您需要使每个 PendingIntent 独一无二，否则您只需用新的覆盖旧的。您可以使用唯一的 ACTION、requestCode 或 DATA 使您的 PendingIntent 独一无二。在您的情况下，我会将 Intent 中的 ACTION 设置为唯一的字符串（即：“BEFORE-WEEK”、“BEFORE-DAY”、“ON-DAY”）并附加出生日期的字符串表示形式，或者，如果一个生日可能出现多次，您可以改为附加此人的姓名，这样可以确保每个 PendingIntent 都是唯一的。
