android - 警报管理器从未在 android 中触发

Question

这段代码有什么问题？我试图在上午 11 点触发警报，我将其设置为上午 10 点，因此它应该在一个小时后触发，但从未发生过

      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);

    }

不要调用 time.clear(); 这会删除所有日历字段，例如日期。
