从一个BroadcastReceiver调用一个活动的完成（）方法 [英] Calling the finish() method of an Activity from a BroadcastReceiver

问题描述

我有2个活动（活动1，活性2）和一个BroadcastReceiver类

I have 2 Activities (Activity1, Activity2) and a BroadcastReceiver class

假设我们现在对活性2，我在那里建立了一个AlarmManager在特定时间运行。

Assume that we are now on Activity2, where I set up an AlarmManager to run at a specific time.

有没有办法给的BroadcastReceiver？

Is there a way to call the finish() method of Activity2 within the onReceive() of the BroadcastReceiver?

我的目标是从活性2回不活动1起onRecieve一个新的Intent（）。

My goal is to return to Activity1 from Activity2 without starting a new Intent in onRecieve().

注：BroadcastReceiver的类没有活性2的活动中注册。它被登记在AndroidManifest.xml

Note: The BroadcastReceiver class is not registered within the Activity of Activity2. It is registered in the AndroidManifest.xml.

推荐答案

您可以使用Activity2class.finish（）;

You can use Activity2class.finish();
