Question

该代码中的问题是什么？我试图在上午11点发出警报，我在上午10点设置它，所以它应该在一个小时后发生，这是从未发生过的

      public void schedulePayment(Context ctxt,int numOfDays) {

        mgr = (AlarmManager)ctxt.getSystemService(Context.ALARM_SERVICE);
        Intent myIntent = new Intent(ctxt, NotificationPayment.class);
        PendingIntent pendingIntent = PendingIntent.getService(ctxt, 0, myIntent, 0);

        Calendar time = Calendar.getInstance();

        time.setTimeInMillis(System.currentTimeMillis());
        time.clear();

        time.set(Calendar.HOUR_OF_DAY, 11);
        time.set(Calendar.MINUTE, 1);
        time.set(Calendar.SECOND, 1);

        long limit_time = time.getTimeInMillis() ;

        //        if(time.before(Calendar.getInstance())){
        //          Log.d("add time ","extra");
        //          limit_time+=AlarmManager.INTERVAL_DAY;
        //        }
        Log.d("in schedule ","done..."+limit_time);
        mgr.setRepeating(AlarmManager.RTC_WAKEUP,         limit_time,AlarmManager.INTERVAL_HALF_HOUR, pendingIntent);

    }

Answer 1

请勿拨打time.clear();这是删除所有日历字段，例如日期。

Answer 2

警报管理器永远不会因为你的limit_time（setRepeating中的第二个参数）小于currentTimeMillis而尝试。尝试使用System.currentTimeMillis + interval而不是limit_time

警报管理器永远不会在android中发射
