AlarmManager仅在日期为现时触发

Question

出于某种原因，我的闹钟仅在日期到来时才会触发，例如12.10 pm，如果是12.10pm。并且所有其他日期都不会被触发。我正在使用AlarmManager，有点困惑。任何人都可以帮忙

这是我在类

中设置闹钟的方法

/**
     * Set up alarm from user input
     */


public void setUpAlarm() {

    // get the time reminder hour and minute from user's input time value
    String[] timeVals = time.split(":");
    int hourOfDay = Integer.parseInt(timeVals[0].trim());
    int minOfDay = Integer.parseInt(timeVals[1].trim());

    // get the Date from User date value

    String[] dateVals = date.split("/");
    int day = Integer.parseInt(dateVals[0].trim());
    int month = Integer.parseInt(dateVals[1].trim());
    int year = Integer.parseInt(dateVals[2].trim());

    Calendar calendar = Calendar.getInstance();

    // set calendar based on user input
    if (month == 1) {
        calendar.set(Calendar.MONTH, Calendar.JANUARY);
        System.out.println("jan");
    } else if (month == 2) {
        calendar.set(Calendar.MONTH, Calendar.FEBRUARY);
        System.out.println("feb");
    } else if (month == 3) {
        calendar.set(Calendar.MONTH, Calendar.MARCH);
        System.out.println("march");
    } else if (month == 4) {
        calendar.set(Calendar.MONTH, Calendar.APRIL);
        System.out.println("april");
    } else if (month == 5) {
        calendar.set(Calendar.MONTH, Calendar.MAY);
        System.out.println("may");
    } else if (month == 6) {
        calendar.set(Calendar.MONTH, Calendar.JUNE);
        System.out.println("june");
    } else if (month == 7) {
        calendar.set(Calendar.MONTH, Calendar.JULY);
        System.out.println("july");
    } else if (month == 8) {
        calendar.set(Calendar.MONTH, Calendar.AUGUST);
        System.out.println("august");
    } else if (month == 9) {
        calendar.set(Calendar.MONTH, Calendar.SEPTEMBER);
        System.out.println("september");
    } else if (month == 10) {
        calendar.set(Calendar.MONTH, Calendar.OCTOBER);
        System.out.println("october");
    } else if (month == 11) {
        calendar.set(Calendar.MONTH, Calendar.NOVEMBER);
        System.out.println("november");
    } else if (month == 12) {
        calendar.set(Calendar.MONTH, Calendar.NOVEMBER);
        System.out.println("december");
    }

    // set year
    calendar.set(Calendar.YEAR, year);
    // set day
    calendar.set(Calendar.DAY_OF_MONTH, day);
    // set hour of day
    calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
    // calendar set Minute of Day
    calendar.set(Calendar.MINUTE, minOfDay);

    // set AM or PM
    if (hourOfDay < 12) {
        calendar.set(Calendar.AM_PM, Calendar.AM);
    } else {
        calendar.set(Calendar.AM_PM, Calendar.PM);
    }

    // create intent for alarm
    Intent myIntent = new Intent(confirmTaskForm.this,
            MyAlarmReceiver.class);

    // create pending intent
    pendingIntent = PendingIntent.getBroadcast(confirmTaskForm.this, 0,
            myIntent, 0);
    // set-up alarm manager
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    // send pendingIntent to alarmManager
    alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(),
            pendingIntent);

}

然后激发广播接收器

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;

/**
 * Feeder class sending data to MyAlarmService
 * @author Aaron
 *
 */
public class MyAlarmReceiver extends BroadcastReceiver{
    int taskID ;

    @Override
    public void onReceive(Context context, Intent intent) {
  Intent service1 = new Intent(context, MyAlarmService.class);
           context.startService(service1);

    }

}

然后是通知
