Question

我正在创建一个简单的时间选择器对话框，当用户设置时间时，我将该时间存储在Calendar实例中。

 public void onTimeSet(TimePicker timePicker, int i, int i1) 
 {
    tpCalendar = Calendar.getInstance();
    tpCalendar.set(Calendar.HOUR_OF_DAY, i);
    tpCalendar.set(Calendar.MINUTE, i1);
    tpCalendar.set(Calendar.SECOND,0);
    updateReminder();
 }

计算updateReminder（）方法中的差异

private void updateReminder() 
{
    long currTime = System.currentTimeMillis();
    long diff = tpCalendar.getTimeInMillis() - currTime;
    long diffInSec = TimeUnit.MILLISECONDS.toSeconds(diff);

    Intent reminderIntent = new Intent(this, ReminderReceiver.class);
      AlarmManager alarmManager = (AlarmManager)     getSystemService(Context.ALARM_SERVICE);

    alarmManager.set(AlarmManager.RTC_WAKEUP, diff,
            PendingIntent.getBroadcast(this, 1, reminderIntent,
            PendingIntent.FLAG_UPDATE_CURRENT));
}

基于差异我正在设置警报。我在Millis（diff变量）中得到了正确的差异。但问题是在设置警报后无论设置了什么差异，它都会在5秒后通知。

在广播接收器中，我只是创建一个通知。我将不胜感激，谢谢。

我做的事情就像我制作AlarmClock时（在TimePicked之后）：

String[] arrTime = time.split(":");
int hour = Integer.parseInt(arrTime[0]);
    int minute = Integer.parseInt(arrTime[1]);
    GregorianCalendar calendar = (GregorianCalendar) GregorianCalendar.getInstance();
    calendar.set(GregorianCalendar.DATE, calendar.get(GregorianCalendar.DATE));
    calendar.set(GregorianCalendar.HOUR_OF_DAY, hour);
    calendar.set(GregorianCalendar.MINUTE, minute);
    calendar.set(Calendar.SECOND, 0);
    calendar.set(Calendar.MILLISECOND, 0);

    Intent intent = new Intent(this, AlarmReceiver.class);
    intent.putExtra("message", message);
    PendingIntent pIntent = PendingIntent.getBroadcast(this, requestCode, intent, 0);
    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pIntent);

时间选择器当前和时间选择器时间Android警报之间的差异
