报警接收器的Andr​​oid组的通知 [英] set notification on alarm receiver android

问题描述

在我的Andr​​oid应用程序，我想以编程方式设置一个alaram。
设置报警器工作正常，但如何申请通知本上recieving报警。

In my android application i would like to set an alaram programmatically. Setting alarm is working properly but how can i apply notification to this on recieving alarm.

我在开发者指南通过通知了。

I have gone through notifications in developer guide.

请找到code。

Calendar cal=Calendar.getInstance();
    Intent alaram=new Intent(Alarmmanager.this,GroupsCheckAlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(Alarmmanager.this, 0, alaram,0);
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),pendingIntent); 
    cal.setTimeInMillis(System.currentTimeMillis()); 

    sendBroadcast(alaram,"setalaram");

和广播接收器

public class GroupsCheckAlarmReceiver extends BroadcastReceiver{ 

@Override 
 public void onReceive(final Context context, Intent intent) { 
 Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show(); 

 } 

据工作正常，但设置的通知我需要设置通知管理器，它只有在活动推广类的工作很好，我怎么可以用它接收和通知。

It is working fine but to set notification i need to set notification manager which works fine only in activity extended class ,how can i use it on receive and notify.

请分享您的宝贵建议。

在此先感谢：）

推荐答案

我想你可以用你的背景在的onReceive 找到 NotificationManager 和呼叫通知：

I think you can use your context in onReceive to find the NotificationManager and call notify:

@Override 
public void onReceive(Context context, Intent intent) {
    NotificationManager notifications = (NotificationManager)
        context.getSystemService(Context.NOTIFICATION_SERVICE);
    notifications.notify( ... );
}

如果你有一个上下文你可以做任何事情！ ：）

If you have a Context you can do just about anything! :)
