android - 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）

问题描述

所以我正在制作 BirthDate Reminder 应用程序，对于我制作的每个 BirthDate，我设置 3 个警报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 让我们说在 8:00 和我的 dayBeforeAlarm 在 8 :01 和我的 onDateAlarm 在 8:02，所以 weekAlarm 应该在 8 点触发，dayBeforeAlarm 应该在 8:01 触发等等......，所以当我制作一个 Birthdate 时它很好并且它工作得很好但是当我制作多个时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，立即触发 dayBeforeAlarm，如果我有 3 个 Birthdates 然后一次 weekAlarm 触发，立即触发 dayBeforeAlarm 和 onDateAlarm。请注意，我制作的所有生日都必须是同一日期. 我怎样才能让它在他们选择的时间开火？

解决方案

您需要使每个都PendingIntent独一无二，否则您只需用新的覆盖旧的。您可以PendingIntent通过使用唯一的 ACTION、requestCode 或 DATA 来使自己独一无二。在您的情况下，我会将 ACTION 设置Intent为唯一的字符串（即：“BEFORE-WEEK”、“BEFORE-DAY”、“ON-DAY”）并附加一个字符串表示的生日，或者如果可以一个生日多次出现，您可以改为附加人名，这样可以确保每个人PendingIntent都是唯一的。
