我正在为约会提醒我创建警报提醒我正在使用以下代码。代码工作得非常好,它显示警报警报,但唯一的问题是,它不区分上午和下午之间的警报,假设我设置警报对于早上7点,当前晚上7点,然后我的警报对话框也会显示。我怎样才能管理上午和下午?我使用此链接进行参考

您没有处理AM / PM。只要把这些代码行......

int timeDifference=0; 
String ampm=splitampmtime[1]; 
if(ampm.matches("PM")){ 
timeDifference=12; 
} 

int splithour = timeDifference+Integer.parseInt(splitstrtime[0]); 
String[] splitsecond = splitstrtime[1].split(" ");

答案 1 :(得分:1)

您可以在save.setOnClickListener()添加AM和PM检查,并相应更改小时值:

save.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        .....

        int splithour = Integer.parseInt(splitstrtime[0]); //10
        String[] splitsecond = splitstrtime[1].split(" "); //40, am

        Log.v("split str second", splitsecond[0]);
        int splitmin = Integer.parseInt(splitsecond[0]); //40

        if(splitsecond[1].equalsIgnoreCase("pm")) {
            splithour += 12;
        } else if(splitsecond[1].equalsIgnoreCase("am") && splithour == 12) {
            splithour = 0;
        }

        ....
    }
}

答案 2 :(得分:1)

请使用: -

alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                                SystemClock.elapsedRealtime() + alarm_time,
                                operation);

取代

alarmManager.set(AlarmManager.RTC_WAKEUP, alarm_time, operation);

读取: -

SystemClock.elapsedRealtime() is the current time in millis add the total time to skip from now to alarm in millis.

我曾经使用这种方法设置闹钟:

    /**
     * Set the Alarm
     *
     * @param context  the activity context
     * @param id       the alarm ID for this app
     * @param hour     the alarm hour
     * @param minute   the alarm minute
     * @param timeZone the timezone am = Calendar.AM or pm = Calendar.PM
     */
    public static void setAlarm(Context context, int id, int hour, int minute, int timeZone) {
        AlarmManager alarm = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.set(Calendar.HOUR, hour);
        calendar.set(Calendar.MINUTE, minute);
        calendar.set(Calendar.AM_PM, timeZone);

        Intent intent = new Intent(context, PopupActivity.class);
        PendingIntent pIntent = PendingIntent.getActivity(context, id, intent, 0);
        alarm.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000 * 60 * 10, pIntent);
    }
