- 我知道之前已经问过这个问题，他们的链接是：
Android: Alarm to be play every 30 minutes and it start from 12:30
Using Alarmmanager to start a service at specific time
Android: Alarm to be play every 30 minutes and it start from 12:30
- 现在，在我的情况下，我想要我的应用程序在一天中的任何时间安装，然后每隔30分钟开始响铃，但不是从安装时开始，而是按照以下示例的顺序...
例如
-->我在上午11:15安装了应用程序。
-->现在，当我的手机时钟敲响了上午11:30它应该开始振铃，然后再次在中午12:00它应该响，然后在下午12:30等等......
- 现在我setRepeating AlarmManager的{{1}}没有解雇，或者即使解雇它也不行......
- 我尝试使用Threads within Service，但有效，但整个过程变得沉重，几乎无法使用。
这是我的代码...........

答案 0 :(得分：2)
嗯，这很糟糕：
cal.set(Calendar.DATE, Calendar.DATE); <-- This sets the day of the month to 5!
cal.set(Calendar.MONTH, Calendar.MONTH); <-- This sets the month to 2 (March)!
你想在这做什么？
为什么不用您想要的参数创建一个日历，如下所示：
Calendar cal = new GregorianCalendar(); // Current date and time
cal.set(Calendar.MILLISECOND, 0);
cal.set(Calendar.SECOND, 0);
// Round minutes up to next multiple of 30
int minutes = cal.get(Calendar.MINUTE);
if (minutes < 30) {
cal.set(Calendar.MINUTE, 30);
} else {
cal.set(Calendar.MINUTE, 0);
cal.add(Calendar.HOUR, 1); // Next hour (will roll the day/month/year over if needed)
}
答案 1 :(得分：1)
另一种方法是花费当前时间并在ms中添加30分钟：
30 mins (30 mins to ms = 60s * 1000ms * 30) = 1800000 ms
long Offset = Calendar.getInstance().getTimeInMillis() + 1800000;
您应该打印为 DURING 调试设置闹钟的时间，以确保它在正确的时间设置为关闭。
在Calendar Instance上使用getTime（）方法，然后在本地时间打印它。
