使用片段切换活动 [英] Using Fragments to switch activities

问题描述

我想创建一个具有与它背后滑活动固定页脚的布局。我被告知要使用碎片，但是这将意味着我将不得不对我现有的活动转化为碎片 - 对吗？下面是我想要达到一个图： http://i.imgur.com/K8Iao。 JPG

I'm trying to create a layout that has a stationary footer with activities that slide behind it. I've been told to use Fragments, but that would mean that I would have to convert my already existing Activities to Fragments - right? Here is a diagram of what I'm trying to achieve: http://i.imgur.com/K8Iao.jpg

推荐答案

我觉得@TarunMaheshwari是想说的是，不是具有 3的活动（如类扩展活动），其中延伸片段（明明有你可能有其他小的改动，以便为code工作），然后创建一个主要活动（与延伸FragmentActivity ），有你想要的可以在3个不同的片段调用静态页脚。

What I think @TarunMaheshwari is trying to say is that instead of having 3 activities (eg. classes with extends activity), replace it with extends fragment (obviously there are other minor changes you might have to make for the code to work) and then create a main activity (with extends FragmentActivity) that has the static footer you want which can call on the 3 different fragments.
