返回Android中堆栈中的其他活动 [英] Go back to different Activity in back stack in Android

问题描述

说我有一个活动堆栈，例如: 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"，并以这样的堆栈结束: 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，点击活动D中的后退"按钮后，我需要将活动C换成活动E，然后降落在活动E上.

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?还是我应该以某种方式构造导航?谢谢！

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

推荐答案

因此，从活动 C转到D finish(); C 活动.

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

最后在活动 D 的backPress方法中调用活动 E 和finish();活动 D

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