如何完成所有活动并关闭android中的应用程序? [英] how to finish all activities and close the application in android?

问题描述

我的应用程序具有以下流程:

My application has the following flow:

主页->屏幕1->屏幕2->屏幕3->屏幕4->屏幕5>主页->屏幕2->主页->屏幕3

Home->screen 1->screen 2->screen 3->screen 4->screen 5>Home->screen 2->Home->Screen 3

我的问题是，当我尝试关闭应用程序时，每次我尝试关闭应用程序时都会打开Home活动.

My problem is that when I am trying to close the application then Home activity opens everytime when I am trying to close the application.

我只想在用户按下主屏幕上的设备的后退键时关闭应用程序.

I just want to close the application when user presses the back key of device on home screen.

推荐答案

有 finishAffinity()方法将完成当前活动和所有父活动，但仅在Android 4.1或更高版本中有效.

There is finishAffinity() method that will finish the current activity and all parent activities, but it works only in Android 4.1 or higher.
