Fragments within Fragments

Question

I\'m wondering if this is actually a bug in the Android API:

I have a setup like so:

┌----┬---------┐
|    |         |
|  1 |    2    |
|    |┌------         


        

Answer 1

Nested fragments are supported in android 4.2 and later

The Android Support Library also now supports nested fragments, so you can implement nested fragment designs on Android 1.6 and higher.

To nest a fragment, simply call getChildFragmentManager() on the Fragment in which you want to add a fragment. This returns a FragmentManager that you can use like you normally do from the top-level activity to create fragment transactions. For example, here’s some code that adds a fragment from within an existing Fragment class:

Fragment videoFragment = new VideoPlayerFragment();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.video_fragment, videoFragment).commit();

and here is a SO post which discuss about best practices for nested fragments.
