alarmManager设置警报以在准确时间而不是分数上工作

Question

在我的应用中，我有以下

    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    Intent i= new Intent("MY_ALARM_NOTIFICATION");
    i.setClass(this, OnAlarmReceive.class);
    i.putExtra("id", id);

    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, id, i,PendingIntent.FLAG_UPDATE_CURRENT);

    //
    Calendar timeCal = Calendar.getInstance();
    timeCal.set(Calendar.HOUR_OF_DAY, hour);
    timeCal.set(Calendar.MINUTE, minutes);
    timeCal.set(Calendar.DAY_OF_MONTH, day);
    timeCal.set(Calendar.MONTH, month) - 1);
    timeCal.set(Calendar.YEAR, year);

    alarmManager.set(AlarmManager.RTC_WAKEUP, timeCal.getTimeInMillis(), pendingIntent);

但是，这可能会返回给我1414526788222 Tue, 28 Oct 2014 20:06:28 GMT，但我想要的是Tue, 28 Oct 2014 20:06:00（没有秒。我一直希望秒数为00）...

Answer 1

只需将秒数设置为零。

timeCal.set(Calendar.SECOND, 0);
