Android 安卓：当noid触发时，活动引用

目前我正在安道尔进行通知工作

这里的代码是通知到达

@Override
public void onReceive(Context context, Intent intent) {

  NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
    mBuilder.setSmallIcon(R.drawable.ic_launcher);
    mBuilder.setTicker("New Task Here!!!");
    if(taskdata.get(0).getDescription().equals(""))
    {
     int stringId = context.getApplicationInfo().labelRes;
     String appname = context.getString(stringId);

     mBuilder.setContentTitle(appname);
    }
    else
    {    
        mBuilder.setContentTitle(taskdata.get(0).getDescription());
    }

    long l = Long.parseLong(taskdata.get(0).getDateTime());

     Date date =new Date(l);

     SimpleDateFormat formatter = new SimpleDateFormat("hh:mm a ");
     String alarmtime = formatter.format(date);
     String dateString= DateFormat.format("dd/MM/yyyy",date).toString();


    mBuilder.setContentText(alarmtime+","+dateString);

    Intent resultIntent = new Intent(context, TaskDetail.class);
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);

    Bundle bundledata = new Bundle();

    bundledata.putString("ImagePath", taskdata.get(0).getImagePath());
    bundledata.putString("Des", taskdata.get(0).getDescription());
    bundledata.putString("DateTime", FlagValue);        
    resultIntent.putExtras(bundledata);

    stackBuilder.addParentStack(TaskDetail.class);

    //ringtone on

    Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    Ringtone r = RingtoneManager.getRingtone(context, notification);
    r.play();

    /* Increase notification number every time a new notification arrives */
    mBuilder.setNumber(++numMessages);
    mBuilder.setAutoCancel(true);
    // Adds the Intent that starts the Ac   tivity to the top of the stack
    stackBuilder.addNextIntent(resultIntent);

    PendingIntent resultPendingIntent =
            stackBuilder.getPendingIntent(
                0,
                PendingIntent.FLAG_UPDATE_CURRENT
            );
   // here this activity will refresh when fire the receive   
    Intent activityintent = new Intent(context,MainActivity.class);


    PendingIntent contentintent = PendingIntent.getActivity(context, 0, activityintent, PendingIntent.FLAG_UPDATE_CURRENT);

    activityintent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    activityintent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

    mBuilder.setContentIntent(resultPendingIntent);

   mNotificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        // notificationID allows you to update the notification later on.
   mNotificationManager.notify(notificationID, mBuilder.build());
}

我的问题是：

• 当无故障发生时，

  MyActivity.class

  Activity将被刷新

我也参考这个链接，但在我的应用程序中不是wok

如果你有任何想法，请帮助我

提前感谢。

在通知功能的末尾添加以下功能

 onCreate(null)

现在到底发生了什么？我正在创建任务剩余应用程序。我已将通知用于任务剩余部分。我正在给特定的时间添加任务。所以，当通知到达时，任务列表活动将刷新，当前任务将从该列表中删除。但不会刷新活动。@A.M@Chirag再次使用startActivity（活动名称）
