           ↳ android.support.v17.leanback.widget.HorizontalGridView


A ViewGroup that shows items in a horizontal scrolling list. The items come from the RecyclerView.Adapter associated with this view.

RecyclerView.Adapter can optionally implement FacetProviderAdapter which provides FacetProvider for a given view type; RecyclerView.ViewHolder can also implement FacetProvider. Facet from ViewHolder has a higher priority than the one from FacetProviderAdapter associated with viewType. Supported optional facets are:

  1. ItemAlignmentFacet When this facet is provided by ViewHolder or FacetProviderAdapter, it will override the item alignment settings set on HorizontalGridView. This facet also allows multiple alignment positions within one ViewHolder.
