如何从堆栈中删除特定活动? [英] How to remove particular activities from stack?

问题描述

比方说，我参加了这一系列活动:

Let's say that I have this stack of activities:

A -> B -> C -> D

活动D具有一个Save按钮.单击该按钮后，我想找回堆栈中的两个活动(C和D是某种向导的一部分，所以我想将它们都删除):

The activity D has a Save button. After click on that button I want to get back two activities in the stack (C and D are part of some kind of wizard so I want to remove them both):

A -> B

这可能吗?

推荐答案

使用FLAG_ACTIVITY_CLEAR_TOP标志从D启动活动B.

Launch the activity B from D with FLAG_ACTIVITY_CLEAR_TOP flag..

Intent a = new Intent(this, B.class);
a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(a);
