AbstractMediaItemPresenter

public abstract class AbstractMediaItemPresenter
extends RowPresenter

Abstract Presenter class for rendering media items in a playlist format. Media item data provided for this presenter can implement the interface MultiActionsProvider, if the media rows wish to contain custom actions. Media items in the playlist are arranged as a vertical list with each row holding each media item's details provided by the user of this class and a set of optional custom actions. Each media item's details and actions are separately focusable. The appearance of each one of the media row components can be controlled through setting theme's attributes. Each media item row provides a view flipper for switching between different views depending on the playback state. A default layout is provided by this presenter for rendering different playback states, or a custom layout can be provided by the user by overriding the playbackMediaItemNumberViewFlipperLayout attribute in the currently specified theme. Subclasses should also override getMediaPlayState(Object) to provide the current play state of their media item model in case they wish to use different views depending on the playback state. The presenter can optionally provide line separators between media rows by setting setHasMediaRowSeparator(boolean) to true.

Subclasses must override onBindMediaDetails(AbstractMediaItemPresenter.ViewHolder, Object) to implement their media item model data binding to each row view.

The OnItemViewClickedListener and OnItemViewSelectedListener can be used in the same fashion to handle selection or click events on either of media details or each individual action views.

AbstractMediaListHeaderPresenter can be used in conjunction with this presenter in order to display a playlist with a header view.
