Question

我有一个应用程序，它从称为任务的Web服务接收数据，然后将任务保存到我的SQLite数据库。我接下来要做的是查询这些任务，然后根据它们被设置为触发的时间设置警报。假设我有一个任务名称“feed”，任务触发的时间是'09：00 AM'（我的时间使用'h：i A'格式）。如何将此时间格式转换为alarmManager可以读取的内容？

public void setAlarm(int uniqueid, int duration) {
    Intent intent = new Intent(this, AlarmReceiver.class);
    intent.setAction(AlarmReceiver.ACTION_ALARM_RECEIVER);//my custom string action name
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, uniqueid, intent, 0);
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

    alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
            + (duration * 1000), pendingIntent);
    Toast.makeText(this, "Alarm set for " + uniqueid, Toast.LENGTH_LONG).show();
}

Answer 1

试试这个，看看它是否适合你

Date mDate = new Date();
Calendar mCalendar = Calendar.getInstance();
mCalendar.setTime(mDate);
mCalendar.add(Calendar.MINUTE, 2);

long alarmInTwoMinutes = mCalendar.getTimeInMillis();

alarmManager.set(AlarmManager.RTC_WAKEUP, alarmInTwoMinutes, pendingIntent);

更新到特定时间的设置

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 9);
calendar.set(Calendar.MINUTE, 30);

long alarmInTwoMinutes = calendar.getTimeInMillis();

要重复，您可以使用

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, alarmInTwoMinutes, pendingIntent)

Answer 2

class animal(object):
    def do_stuff(self):
        return self.__yell() 

class dog(animal):
    def yell(self):
        print("yelling")

使用毫秒。
