Question

如何为我的数据库值设置警报，因为db值是字符串。例如我的日期和时间是10:33 AM4 / 11/2015。

    Date m_date = new Date();              
   SimpleDateFormat m_dateFormat = new SimpleDateFormat("hh:mm aayyyy-MM-dd");

            try {

                m_date = m_dateFormat.parse("1:40 PM4/11/2015");
            } catch (ParseException p_e) {
                p_e.printStackTrace();
            }
            m_date.getTime();

            String s = String.valueOf(m_date.getTime());
            System.out.println("Pakistan " + s);
          //  Log.d("Tag Name", s);
            long foo = Long.parseLong(s);
            System.out.println("Pakistan " + foo);
            long time = new GregorianCalendar().getTimeInMillis() + foo;
            Intent intentAlarm = new Intent(this, AlarmReceiver.class);
            AlarmManager alarmManager = (AlarmManager)  getSystemService(Context.ALARM_SERVICE);
            alarmManager.set(AlarmManager.RTC_WAKEUP, time, PendingIntent.getBroadcast(this, 1, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
            Toast displayVal = Toast.makeText(getApplicationContext(), "Alaram Set After 10 sec it will work", Toast.LENGTH_LONG);
            displayVal.show();

首先，您的m_dateFormat hh：mm aayyyy-MM-dd 用于＆＃34; 1：40 PM4 / 11 / 2015＆＃34;

请使用＆＃34; hh：mm aaMM / dd / yyyy ＆＃34;

然后你不需要从字符串中解析时间。

最后，使用AlarmManager.RTC_WAKEUP时，AlarmManager的时间 UTC时间

Date m_date = new Date(); SimpleDateFormat m_dateFormat = new SimpleDateFormat("hh:mm aaMM/dd/yyyy"); try { m_date = m_dateFormat.parse("1:40 PM4/11/2015"); } catch (ParseException p_e) { p_e.printStackTrace(); } long time = m_date.getTime(); System.out.println("Pakistan " + time); Intent intentAlarm = new Intent(this, AlarmReceiver.class); AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, time, PendingIntent.getBroadcast(this, 1, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
