All Implemented Interfaces:

android.widget.Adapter, android.widget.ListAdapter, android.widget.SpinnerAdapter

public class StormListAdapter
extends android.widget.BaseAdapter

The base adapter used for displaying Storm views in a list. Using an adapter to do such a task has the benefit of view recycling which makes the content smooth to scroll. This adapter only supports Model classes which have a defined Holder counter-class. Usage Problems Problems can arise with this method of rendering content, specifically with render efficiency where the views are not being recycled because there is only 1 of its view type in the list. This is the equivalent of having all of the views inflated into a ScrollView. The smoothness of the scrolling (depending on how much content there is) diminishes with the amount of unique content that the list is rendering.
