从Android的服务发送通知 [英] Sending a notification from a service in Android

问题描述

我有一个服务运行，并想发送通知。太糟糕了，通知对象需要一个背景下，像一个活动，而不是服务。

I have a service running, and would like to send a notification. Too bad, the notification object requires a context, like an Activity, and not a service.

你知道什么方法可以通过传递？我想卜似乎丑陋创建活动的每个通知，我不能找到一种方法来启动一个活动，没有任何看法。

Do you know any way to by pass that ? I tried to create an Activity for each notification bu it seems ugly, and I can't find a way to launch an Activity without any view.

推荐答案

两个活动和服务实际上延长 上下文 ，所以你可以简单地使用这作为上下文的服务范围内。

Both Activity and Service actually extend Context so you can simply use this as your Context within your Service.

NotificationManager notificationManager =
    (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(/* your notification */);
PendingIntent pendingIntent = /* your intent */;
notification.setLatestEventInfo(this, /* your content */, pendingIntent);
notificationManager.notify(/* id */, notification);
