Android的碎片和活动 [英] Android Fragments and Activities

问题描述

在谈到下图：

http://developer.android.com/guide/components/fragments.html

可能有人请，请解释为什么谷歌建议使用2个独立的活动，在手机和平​​板一个活动？ 如果我有code的活性的管理片段B（对于平板电脑）我为什么要重复同样的code在b活动的电话？

Could someone please please explain why Google suggests to use 2 separate activities on a Phone and a single activity on a Tablet? If I have code in activity A to manage Fragment B (for a Tablet) why should I repeat the same code in Activity B for a phone?

看来，一个电话我仍然可以使用1活动，以及（唯一的活动A）和替换的片段，这样可以减少冗余code？

It seems that for a Phone I can still use 1 activity as well (only activity A) and replace fragments, this could reduce redundant code?

感谢。

推荐答案

我得到你的意思。

您可以使用一个片段容器和更换片段，定义界面选择回调。谷歌只是它这样也许它更清晰的为那些谁来自世界的活动我猜。

You could use a fragment container and replace the fragments, define interface for selection callback. Google just does it this way maybe its clearer for those who come from the activities world i guess.
