Public methods

onBindViewHolder

added in version 22.1.0
void onBindViewHolder (Presenter.ViewHolder viewHolder, 
                Object item)

Binds a View to an item.

Parameters
viewHolder Presenter.ViewHolder

item Object

onCreateViewHolder

added in version 22.1.0

Creates a new View.

Parameters
parent ViewGroup

Returns
AbstractDetailsDescriptionPresenter.ViewHolder

onUnbindViewHolder

added in version 22.1.0
void onUnbindViewHolder (Presenter.ViewHolder viewHolder)

Unbinds a View from an item. Any expensive references may be released here, and any fields that are not bound for every item should be cleared here.

Parameters
viewHolder Presenter.ViewHolder

onViewAttachedToWindow

added in version 22.1.0
void onViewAttachedToWindow (Presenter.ViewHolder holder)

Called when a view created by this presenter has been attached to a window.

This can be used as a reasonable signal that the view is about to be seen by the user. If the adapter previously freed any resources in onViewDetachedFromWindow(ViewHolder) those resources should be restored here.

Parameters
holder Presenter.ViewHolder: Holder of the view being attached

onViewDetachedFromWindow

added in version 22.1.0
void onViewDetachedFromWindow (Presenter.ViewHolder holder)

Called when a view created by this presenter has been detached from its window.

Becoming detached from the window is not necessarily a permanent condition; the consumer of an presenter's views may choose to cache views offscreen while they are not visible, attaching and detaching them as appropriate.

Any view property animations should be cancelled here or the view may fail to be recycled.

Parameters
holder Presenter.ViewHolder: Holder of the view being detached

Protected methods

onBindDescription

added in version 22.1.0
void onBindDescription (AbstractDetailsDescriptionPresenter.ViewHolder vh, 
                Object item)

Binds the data from the item to the ViewHolder. The item is typically associated with a DetailsOverviewRow or PlaybackControlsRow.

Parameters
vh AbstractDetailsDescriptionPresenter.ViewHolder: The ViewHolder for this details description view.
item Object: The item being presented.
