RowsFragment.MainFragmentAdapter

Overview

Interface that defines the interaction between BrowseFragment and its main content fragment. The key method is BrowseFragment.MainFragmentAdapter.getFragment(), it will be used to get the fragment to be shown in the content section. Clients can provide any implementation of fragment and customize its interaction with BrowseFragment by overriding the necessary methods.

Clients are expected to provide an instance of BrowseFragment.MainFragmentAdapterRegistry which will be responsible for providing implementations of BrowseFragment.MainFragmentAdapter for given content types. Currently we support different types of content - ListRow, PageRow or any subtype of Row. We provide an out of the box adapter implementation for any rows other than PageRow - RowsFragment.MainFragmentAdapter.

PageRow is intended to give full flexibility to developers in terms of Fragment design. Users will have to provide an implementation of BrowseFragment.MainFragmentAdapter and provide that through BrowseFragment.MainFragmentAdapterRegistry. BrowseFragment.MainFragmentAdapter implementation can supply any fragment and override just those interactions that makes sense.
