Methods

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 GridLayoutManager.SpanSizeLookup.getSpanIndex(int, int).

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

Returns:

The span index of the View.

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:

The number of spans occupied by this View.
