通知Android？

Question

我是android编程的新手。我想知道可以在这样的时间显示通知，时间格式为String（2014-1-10 1:30:33）？ 无论应用程序是否运行，都会给出（2014-1-1 1:30:33）并显示在2014-1-10 1:30:33。 \\

  public void Notification(String s)
{
        String ns = Context.NOTIFICATION_SERVICE;

        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

        int icon = R.drawable.notification_icon;
        CharSequence tickerText = "Ready for Play time."; // ticker-text
        long when = System.currentTimeMillis();
        Context context = getApplicationContext();
        CharSequence contentTitle = "Play Time";
        CharSequence contentText = "Your match is at "+s;

        Intent notificationIntent = new Intent(this,ScheldueNotification .class);
        //PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
        PendingIntent pendingNotificationIntent = PendingIntent.getActivity( this.getApplicationContext(),0, notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);
        Notification notification = new Notification(icon, tickerText, when);
        notification.setLatestEventInfo(context, contentTitle, contentText, pendingNotificationIntent);
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
        // and this

        mNotificationManager.notify(MY_NOTIFICATION_ID, notification);

        Intent myIntent = new Intent(MainActivity.this, myReceiver.class);
          PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, myIntent,0);

          AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
          SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss ");

          /*java.util.Date date;
                try {
                    date = formatter.parse(getCurrentTime());
                } catch (java.text.ParseException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }*/


          try {
              alarmManager.set(AlarmManager.RTC,(sdf.parse(getCurrentTime())).getTime(), pendingIntent);
          } catch (java.text.ParseException e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
          }

        notification.defaults |= Notification.DEFAULT_SOUND;
        notification.vibrate = new long[] { 0, 100, 200, 300 };
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        //alert();

}

编辑：在我的代码中。 运作不正常。

您可以为此使用警报管理器。 请参阅此链接上的Alexander Fragotsis答案。
