HorizontalGridView

class HorizontalGridView : BaseGridView

kotlin.Any
   ↳ android.view.View
     ↳ android.view.ViewGroup
       ↳ androidx.recyclerview.widget.RecyclerView
         ↳ androidx.leanback.widget.BaseGridView
           ↳ androidx.leanback.widget.HorizontalGridView

A android.view.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.

fun getFadingLeftEdgeLength(): Int

Returns the left edge fading length in pixels.

getFadingLeftEdgeOffset

Added in 1.0.0
fun getFadingLeftEdgeOffset(): Int

Returns the distance in pixels between fading start position and left padding edge. The fading start position is positive when start position is inside left padding area. Default value is 0, means that the fading starts from left padding edge.

getFadingRightEdge

getFadingRightEdgeOffset

Added in 1.0.0
fun getFadingRightEdgeOffset(): Int

Sets the distance in pixels between fading start position and right padding edge. The fading start position is positive when start position is inside right padding area. Default value is 0, means that the fading starts from right padding edge.

setFadingLeftEdge

Added in 1.0.0
fun setFadingLeftEdge(fading: Boolean): Unit

Sets the fade out left edge to transparent. Note turn on fading edge is very expensive that you should turn off when HorizontalGridView is scrolling.

setFadingLeftEdgeLength

Added in 1.0.0
fun setFadingLeftEdgeLength(fadeLength: Int): Unit

Sets the left edge fading length in pixels.

setFadingLeftEdgeOffset

Sets the distance in pixels between fading start position and left padding edge. The fading start position is positive when start position is inside left padding area. Default value is 0, means that the fading starts from left padding edge.

setFadingRightEdge

Added in 1.0.0
fun setFadingRightEdge(fading: Boolean): Unit

Sets the fade out right edge to transparent. Note turn on fading edge is very expensive that you should turn off when HorizontalGridView is scrolling.

setFadingRightEdgeLength

Added in 1.0.0
fun setFadingRightEdgeLength(fadeLength: Int): Unit

Sets the right edge fading length in pixels.

setFadingRightEdgeOffset

Added in 1.0.0
fun setFadingRightEdgeOffset(fadeOffset: Int): Unit

Returns the distance in pixels between fading start position and right padding edge. The fading start position is positive when start position is inside right padding area. Default value is 0, means that the fading starts from right padding edge.

setNumRows

Added in 1.0.0
fun setNumRows(numRows: Int): Unit

Sets the number of rows. Defaults to one.

setRowHeight

Added in 1.0.0
fun setRowHeight(height: Int): Unit

Sets the row height.

Parameters
height: Int

May be WRAP_CONTENT, or a size in pixels. If zero, row height will be fixed based on number of rows and view height.
