Android的突然离开活动堆栈 [英] Android Popping off the Activity Stack

问题描述

在我们的应用程序，我们有活动A，B，C，D和E的用户通常会从A到E，通过对B移动，C，D。

In our app, we have Activities A,B,C,D, and E. The user usually goes from A to E, moving through B,C,D.

在活动Ë我们要回到A，并从堆栈中去掉B，C，D的。我们不希望给E重新创建。

In Activity E we want to go back to A, and get rid of B,C,D from the stack. We don't want to recreate A from E.

我如何'流行过'B，C，D从堆栈，然后返回到A？

How do I 'pop off' B,C,D from the stack and then return to A?

推荐答案

如果一个已经在运行，你可以使用<一个href="http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_CLEAR_TOP">FLAG_ACTIVITY_CLEAR_TOP标志开始的意图回到A的时候。

If A is already running, you can use the FLAG_ACTIVITY_CLEAR_TOP flag when starting an intent to go back to A.
