在Android的后台堆栈中返回不同的Activity [英] Go back to different Activity in back stack in Android

问题描述

假设我有一个这样的活动堆栈:A -> B -> C -> D

Say I have an activity stack as such: A -> B -> C -> D

我想创建一个新的活动E"，最终得到一个这样的堆栈:A -> B -> E

I would like to create a new activity "E", and end up with a stack like this: A -> B -> E

基本上，在活动 D 中点击返回按钮后，我需要将活动 C 换成活动 E，然后登陆它.

Basically, upon hitting the back button in activity D, I need to swap out activity C for activity E, and land on it.

这可能吗?还是我应该以不同的方式构建导航?谢谢！

Is this possible? Or should I be structuring the navigation differently somehow? Thanks!

推荐答案

so while 从活动 C 到 D finish(); C 活动.

so while going from activity C to D finish(); C activity.

最后在ActivityD的backPress方法调用activityE和finish();ActivityD

At last at backPress method of Activity D call activity E and finish(); Activity D
