在相同的布局中使用两次片段

Question

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.

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).

Is what i want to do possible?

Answer 1

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.

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

You could create duplicate classes. One from the other. And rename the second class to another name.

And set the second layout to

  class="name of second class"

Then rename the wigdets for use in the second renamed class that is identical to the first except different widget id's.
