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

问题描述

我有一项服务正在运行，我想发送通知.太糟糕了，通知对象需要一个 Context，就像一个 Activity，而不是一个 Service.

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.

你知道有什么方法可以绕过吗?我试图为每个通知创建一个 Activity 但它看起来很丑，而且我找不到一种方法来启动 Activity 没有任何 View.

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

推荐答案

Activity 和 Service 实际上都是 extend Context 所以你可以简单地使用 this作为您的 Service 中的 Context.

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

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