Class AbsHListView.RecycleBin

java.lang.Object

it.sephiroth.android.library.widget.AbsHListView.RecycleBin

Enclosing class:

AbsHListView

public class AbsHListView.RecycleBin
extends java.lang.Object

The RecycleBin facilitates reuse of views across layouts. The RecycleBin has two levels of storage: ActiveViews and ScrapViews. ActiveViews are those views which were onscreen at the start of a layout. By construction, they are displaying current information. At the end of layout, all views in ActiveViews are demoted to ScrapViews. ScrapViews are old views that could potentially be used by the adapter to avoid allocating views unnecessarily.
