在相同的布局使用两次片段 [英] Use fragment twice in same layout

问题描述

是否有可能在一个布局重用片段两次吗？我有两个标签，标签A和标签乙..每个选项卡显示由左侧项目和右侧的所选项目的细节（B型或）列表的视图的布局。 详细信息视图（右侧窗格）是两种类型的列表一样的，所以我想把它留而列表取决于所选什么标签交换出去。

Is it possible to reuse a fragment twice in one layout? I have a layout of two tabs, Tab A and Tab B.. each tab displays a view that consists of a list (of type A or B) of items on the left and the details of the selected item on the right. The "detail view" (on the right pane) is the same for both types of lists, so I want to have it remain while the list is swapped out depending on what tab is selected.

我曾尝试，包括在布局XML为两个标签的细节片段，但获得有关重复运行时错误。于是我试着在运行时有FragmentTransaction动态地添加他们却得到了一个类似的错误（片段已添加）。

I have tried to include the details fragment in layout XML for both tabs but get a runtime error about duplicates. So then I tried to add them dynamically at runtime with a FragmentTransaction but get a similar error (fragment has already been added).

是我想做的事情可能吗？

Is what i want to do possible?

推荐答案

您应该添加片段动态设定不同的标记每个片段，然后用 getFragmentManager（）findFragmentByTag（TAG）; 在每个选项卡视图中可以添加的FrameLayout ，然后用 FragmentTransaction.replace 功能。

You should add the fragments dynamically setting different TAGs for each fragment and then finding them with getFragmentManager().findFragmentByTag("TAG"); In each TAB view you can add a FrameLayout and then use FragmentTransaction.replace function.

我有一个类似的问题（添加相同片段多次在 ViewFlipper ），并利用它解决不同的标签。

I had a similar problem (adding the same fragment many times in a ViewFlipper) and solved it by using different tags.
