Question

我在我的应用程序中使用了警报管理器，我希望在一天之后重复警报。一天后调用一次后应该调用警报。请帮忙。提前谢谢。

if(str_freqSchedule.equals(checkForDaily)){
            Calendar calendar = Calendar.getInstance();
            //calendar.set(Calendar.DAY_OF_YEAR, calendar.get(Calendar.DAY_OF_YEAR));
            calendar.set(Calendar.HOUR_OF_DAY, hr);
            calendar.set(Calendar.MINUTE, min);
            calendar.set(Calendar.SECOND,0);

            Intent intent = new Intent(this, AlarmReceiverActivity.class);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(
                    this.getApplicationContext(), j, intent, PendingIntent.FLAG_CANCEL_CURRENT);
            AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),(24*60*60*1000),pendingIntent);
            j++;

        }

根据android文档，最好使用不精确的重复而不是setExactRepeating，记住电池消耗。

      public void scheduleAlarms(AlarmManager mgr, PendingIntent pi, Context context) 
                {

                    // every day at scheduled time 
                    Calendar calendar = Calendar.getInstance();
                   // if it's after or equal 9 am schedule for next day
                   if (Calendar.getInstance().get(Calendar.HOUR_OF_DAY) >= 9) {
                        calendar.add(Calendar.DAY_OF_YEAR, 1); 
                    }
                    calendar.set(Calendar.HOUR_OF_DAY, 9);
                    calendar.set(Calendar.MINUTE, 0);
                    calendar.set(Calendar.SECOND, 0);

              mgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi);
    }

希望下面的代码会有所帮助，我在我的应用程序中使用了相同的代码。这里在AlarmManager类中传递的用于重复的参数应该是24 * 60 * 60 * 1000

AlarmManager am = (AlarmManager) ct.getSystemService(Context.ALARM_SERVICE);         
Intent intent1 = new Intent(ct, TimeAlarm.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(ct, 0,intent1, PendingIntent.FLAG_CANCEL_CURRENT);

Date curr=new Date();
curr.setHours(h);
curr.setMinutes(m);
c.setTime(curr);
c.set(Calendar.SECOND, 0);

Calendar c1 = Calendar.getInstance();
am.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(),24*60*60*1000, pendingIntent);

Answer 3

试试这个

AlarmManager am = (AlarmManager) ct.getSystemService(Context.ALARM_SERVICE);         
Intent intent1 = new Intent(ct, TimeAlarm.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(ct, 0,intent1, PendingIntent.FLAG_UPDATE_CURRENT);
am.setRepeating(AlarmManager.RTC_WAKEUP, yourtime,AlarmManager.INTERVAL_DAY, pendingIntent);

Answer 4

// Retrieve a PendingIntent that will perform a broadcast
Intent alarmIntent = new Intent(HomeContactActivity.this,
        AlarmReceiver.class);
pendingIntent = PendingIntent.getBroadcast(
        HomeContactActivity.this, 0, alarmIntent, 0);

AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

// Set the alarm to start at 10:00 AM
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 10);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);




manager.setRepeating(AlarmManager.RTC_WAKEUP,
        calendar.getTimeInMillis(), 86400000, // for repeating in every 24 hours
        pendingIntent);
