GridLayoutManager.LayoutParams


public class GridLayoutManager.LayoutParams extends 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

Added in 1.0.0
public int getSpanIndex()

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 getSpanIndex.

If the View occupies multiple spans, span with the minimum index is returned.

Returns
int

The span index of the View.

getSpanSize

Added in 1.0.0
public int getSpanSize()

Returns the number of spans occupied by this View. If the View not laid out yet, the return value is undefined.

Returns
int

The number of spans occupied by this View.
