android - 每天触发一次以上的通知

Question

我的 alarmManager 似乎每小时触发一次通知，而不是每天一次。我希望我的应用每天触发一次通知，用户将在该通知中单击该通知并被带到一个新的 Activity 中，在那里他们将学习一个新单词/定义。

我没有包含 Word.class 和 Definition.class，我认为问题可能与定义类有关，没有“退出”，唯一的选择是点击主页按钮或返回

Answer 1

这是使用 RTC 的一个示例。

大约在 21:21 响起闹钟，每天同一时间重复一次:

// Set the alarm to start at approximately 09:21 p.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 21);
calendar.set(Calendar.MINUTE, 21);

// With setInexactRepeating(), you have to use one of the AlarmManager interval
// constants--in this case, AlarmManager.INTERVAL_DAY.

alarmMgr.setInexactRepeating(AlarmManager.RTC, calendar.getTimeInMillis(),
        AlarmManager.INTERVAL_DAY, alarmIntent);
