问题描述

我有活动 A 启动活动 B，活动 B 启动活动 C:

I have activity A that starts activity B which starts activity C:

A -> B -> C

A -> B -> C

当用户单击活动 C 中的按钮时，我想将 A 带到堆栈顶部并取 B &C 完全出栈.有没有办法做到这一点?

When a user clicks on a button in activity C, I want to bring A to the top of the stack and take B & C completely out of the stack. Is there a way to do this?

推荐答案

您可以使用 FLAG_ACTIVITY_CLEAR_TOP 标志用于重新启动活动 A.

You can use the FLAG_ACTIVITY_CLEAR_TOP flag on the intent to restart activity A.
