固定页眉和页脚的Android应用 [英] Fixed header and footer in android app
问题描述
我要使用固定的页眉和页脚在我的Android应用程序，但每次新活动开始时，页面刷新，并都页眉和页脚重装。结果
我怎样才能让他们通过固定了应用程序生命周期，让他们从来没有重装，虽然我可以隐藏，删除和添加项目呢？
I want to use fixed header and footer in my android app, but every time a new activity starts, the page refreshes and both the header and footer reload.
How can I make them fixed through out the application life cycle so that they never reload, although I can hide, remove and add items to them?
我已经使用了包括标签，这不是我想要的。
I've used the include tag and it's not what I want
推荐答案
您可以使用一个活性的页眉，页脚和内容片段。相反，开始新的活动，你会改变的内容片段。
You may use one Activity with header, footer and the content Fragment. Instead of starting new Activity, you'll change the content Fragment.
但是，这不是既不由Android也不是由用户的预期。你也需要某种形式的后退按钮处理，状态保存/恢复等。你确定你想要做你所描述的？
But. This is not expected neither by Android nor by user. Also you need some kind of Back button handling, state saving/restoring and so on. Are you sure that you want to do what you described?

另外，如果你想在Android 3.0之前（API级别11），你需要的支持库
对于自定义动画中天
Also if you want to use fragments on Android prior 3.0 (API level 11), you'll need the Support Library For custom transit animation
