如何火从BroadcastReceiver的通知（不能用大多数方法，并不能使用本）？ 我需要它从DB我已经做到了信息打开一个活动，但现在必须在忽略了最低的工作方式，我不能用这个

how to fire notification from BroadcastReceiver (can't use most methods and can't use "this")? I need it to open a activity with info from the DB I already did it but now must of the methods dosen't work and I cant use "this"

推荐答案

在的onReceive 方法，你会得到一个上下文对象。所以用它来获得 NotificationManager 和消防您的通知。

In the onReceive method you get a Context object. So use it to get the NotificationManager and fire your notification.

public void onReceive(Context ctx, Intent intent) {
    NotificationManager nm = (NotificationManager)ctx.getSystemService(Context.NOTIFICATION_SERVICE);
    //Create the notification here.
    nm.notify(NOTIFICATION_ID, notification);
}

这是活动和服务从上下文推导。这就是为什么，在许多（或所有）的上下文的实例方法，你可以使用这。如果这是你的话，那么你可以使用上下文您在收到的onReceive 。

An Activity and a Service are derived from Context. That's why, in many (or all) of the instance methods of a context, you can use this. If that's your case, then you can use the Context you receive in onReceive.
