结算活动堆栈不工作 [英] Clearing activity stack is not working

问题描述

我有以下设置为我的活动：

I have the following setup for my activities:

A（noHistory） - > B - >Ç - >ð - >电子

所以，当我开始动鄂从活动ð我想电子成为根系活力和清除后退堆栈的其余部分。

So when I start activity E from activity D I want E to become the root activity and clear the rest of the back stack.

我跟这里很多帖子中提到的解决方案，这是对下列标志添加到我的意图：

I followed the solution mentioned in many posts here which is to add the following flags to my Intent:

final Intent explicitIntent = new Intent(this,
                E.class);
        explicitIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
        explicitIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        this.startActivity(explicitIntent);

然而，动鄂（这是没有运行之前）不会成为回堆栈的根。相反，只是活动ð从后面堆栈中删除， C 和 B 仍然存在，如果我preSS后退按钮。

However, Activity E (which was not running before) does not become the root of the back stack. Instead, just Activity D is deleted from the back stack, C and B are still there if I press the back button.

那么，我要实现的SDK＆LT真的不可能什么; 11如下所述：<一href=\"http://stackoverflow.com/questions/3473168/clear-the-entire-history-stack-and-start-a-new-activity-on-android\">Clear整个历史堆栈，并在Android 开始新的活动？

So is what I want to achieve really impossible in SDK < 11 as described here: Clear the entire history stack and start a new activity on Android ?

推荐答案

在结束我只是做了作为RASEL建议（在评论我的问题）
当进入活动专口呼吁活动乙完成，C，D，让他们堆栈。

In the end I just did as Rasel advised (in the comments to my question) When entering activity E i called finish on activities B,C,D to get them off the stack.
