FullWidthDetailsOverviewRowPresenter

public class FullWidthDetailsOverviewRowPresenter
extends RowPresenter

java.lang.Object
   ↳ android.support.v17.leanback.widget.Presenter
     ↳ android.support.v17.leanback.widget.RowPresenter
       ↳ android.support.v17.leanback.widget.FullWidthDetailsOverviewRowPresenter

Renders a DetailsOverviewRow to display an overview of an item. Typically this row will be the first row in a fragment such as the DetailsFragment. The View created by the FullWidthDetailsOverviewRowPresenter is made in three parts: logo view on the left, action list view on the top and a customizable detailed description view on the right.

The detailed description is rendered using a Presenter passed in FullWidthDetailsOverviewRowPresenter(Presenter). Typically this will be an instance of AbstractDetailsDescriptionPresenter. The application can access the detailed description ViewHolder from getDetailsDescriptionViewHolder().

The logo view is rendered using a customizable DetailsOverviewLogoPresenter passed in FullWidthDetailsOverviewRowPresenter(Presenter, DetailsOverviewLogoPresenter). The application can access the logo ViewHolder from getLogoViewHolder().

To support activity shared element transition, call setListener(Listener) with FullWidthDetailsOverviewSharedElementHelper during Activity's onCreate(). Application is free to create its own "shared element helper" class using the Listener for image binding. Call setParticipatingEntranceTransition(boolean) with false

The view has three states: STATE_HALF STATE_FULL and STATE_SMALL. See DetailsFragment where it switches states based on selected row position.
