这是一个使用 AlarmManager 的示例代码，您需要根据自己的需求更改日期和时间。我将其设置为今天的 23:59。
// 当闹钟触发时要启动的待处理意图。在这种情况下，打开 AlarmActivity
Intent intent = new Intent(getApplicationContext(), AlarmActivity.class);
PendingIntent alarmIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
// 将闹钟设置为今天的 23:59
calendar = Calendar.getInstance(TimeZone.getTimeZone("IST"));
calendar.set(Calendar.HOUR_OF_DAY, 23);
calendar.set(Calendar.MINUTE, 59);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(),
alarmIntent);
在给定的日期和时间，意图将被触发，因此您需要在 AlarmActivity 中编写逻辑。您还可以将意图更改为启动服务或触发广播消息。
英文:
Here's a sample code of using the AlarmManager, you will need to change date and time according to your needs. I put it for today at 23:59
// Pending intent to be fired when alarm occurrs. In this case, open the AlarmActivity
Intent intent = new Intent(getApplicationContext(), AlarmActivity.class);
PendingIntent alarmIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
// Set the alarm for today at 23:59
calendar = Calendar.getInstance(TimeZone.getTimeZone("IST"));
calendar.set(Calendar.HOUR_OF_DAY, 23);
calendar.set(Calendar.MINUTE, 59);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(),
alarmIntent);
In the given date-time the Intent will be fired so you need to make you logic in the AlarmActivity. You could also change the intent to start a Service or fire a Broadcast message
