LayoutParams
open class LayoutParams : RecyclerView.LayoutParams
LayoutParams used by GridLayoutManager.
Note that if the orientation is VERTICAL
, the width parameter is ignored and if the orientation is HORIZONTAL
the height parameter is ignored because child view is expected to fill all of the space given to it.

Public methods
getSpanIndex
open fun getSpanIndex(): Int
Returns the current span index of this View. If the View is not laid out yet, the return value is undefined
.
Starting with RecyclerView 24.2.0, span indices are always indexed from position 0 even if the layout is RTL. In a vertical GridLayoutManager, leftmost span is span 0 if the layout is LTR and rightmost span is span 0 if the layout is RTL. Prior to 24.2.0, it was the opposite which was conflicting with SpanSizeLookup#getSpanIndex(int, int)
.
If the View occupies multiple spans, span with the minimum index is returned.
