A DetailsOverviewRowPresenter 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. View created by DetailsOverviewRowPresenter is made in three parts:
ImageView on the left, action list view on the bottom and a customizable detailed
description view on the right.
The detailed description is rendered using a Presenter passed in
DetailsOverviewRowPresenter(Presenter). User can access detailed description
ViewHolder from mDetailsDescriptionViewHolder.
To participate in activity transition, call setSharedElementEnterTransition(Activity, String) during Activity's onCreate().
Because transition support and layout are fully controlled by DetailsOverviewRowPresenter, developer can not override DetailsOverviewRowPresenter.ViewHolder for adding/replacing views of DetailsOverviewRowPresenter. If developer wants more customization beyond replacing detailed description , he/she should write a new presenter class for row object.

Returns the background color. If no background color was set, transparent is returned.
Gets the listener for Action click events.

override onSelectLevelChanged(ViewHolder).
Sets the background color. If not set, a default from the theme will be used.
Sets the listener for Action click events.
Set enter transition of target activity (typically a DetailActivity) to be transiting into overview row created by this presenter. The transition will be cancelled if overview image is not loaded in a default timeout period.
It assumes shared element passed from calling activity is an ImageView; the shared element transits to overview image on the left of detail overview row, while bounds of overview row grows and reveals text and buttons on the right.
The method must be invoked in target Activity's onCreate().

The method must be invoked in target Activity's onCreate().
Sets the layout style to be large or small. This affects the height of the overview, including the text description. The default is large.
Called to create a ViewHolder object for a Row. Subclasses will override this method to return a different concrete ViewHolder object.

Subclass may override this to respond to selected state changes of a Row. Subclass may make visual changes to Row view but must not create animation on the Row view.
Callback when select level is changed. The default implementation applies
the select level to setSelectLevel(RowHeaderPresenter.ViewHolder, float)
when getSelectEffectEnabled() is true. Subclasses may override
this function and implement a different select effect. In this case, you
should also override isUsingDefaultSelectEffect() to disable
the default dimming effect applied by the library.
