小编use*_*256的帖子

我正在使用此通知代码：

package com.example.mega;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;


public class TimeAlarm extends BroadcastReceiver {

     NotificationManager nm;

     @Override
     public void onReceive(Context context, Intent intent) {
         nm = (NotificationManager) context
             .getSystemService(Context.NOTIFICATION_SERVICE);
         CharSequence from = "Tech";
         CharSequence message = "Check out our NEW COLLECTION !!";
         PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
             new Intent(), 0);
         Notification notif = new Notification(R.drawable.icon,
             "Check out our NEW COLLECTION !!" , System.currentTimeMillis());
         notif.setLatestEventInfo(context, from, message, contentIntent);
         nm.notify(1, notif);
    }
}

如您所见，由于我没有使用过AlarmManager的经验，所以我还没有添加它，所以我是android的新手。我应该在代码中添加什么才能每24小时显示一次通知？
