Answer 1

The container parameter passed to onCreateView() is the parent ViewGroup (from the activity's layout) in which your fragment layout will be inserted. Rest you can refer to this link

Answer 2

Not sure why this question was down voted. IMO it's a good question trying to understand what the framework is giving us from its callbacks.

I have the same question, and after reading some official docs, here is my theory:

To make it more specific, I think the container is the FragmentContainerView in this example. Basically it's the resource id which you add your fragment to. For example, if we do

fragmentTransaction.add(R.id.container_view, fragment).commitNow();

Then the container is the ViewGroup identified by R.id.container_view.
