DetailsOverviewLogoPresenter

public class DetailsOverviewLogoPresenter
extends Presenter

java.lang.Object
   ↳ android.support.v17.leanback.widget.Presenter
     ↳ android.support.v17.leanback.widget.DetailsOverviewLogoPresenter

Presenter that responsible to create a ImageView and bind to DetailsOverviewRow. The default implementation uses getImageDrawable() and binds to ImageView.

Default implementation assumes no scaleType on ImageView and uses intrinsic width and height of getImageDrawable() to initialize ImageView's layout params. To specify a fixed size and/or specify a scapeType, subclass should change ImageView's layout params and scaleType in onCreateView(ViewGroup).

Subclass may override and has its own image view. Subclass may also download image from URL instead of using getImageDrawable(). It's subclass's responsibility to call notifyOnBindLogo(FullWidthDetailsOverviewRowPresenter.ViewHolder) whenever isBoundToImage(ViewHolder, DetailsOverviewRow) turned to true so that activity transition can be started.
