@Override public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
    if (!isInset(view, parent)) return;

    GridLayoutManager.LayoutParams layoutParams = (GridLayoutManager.LayoutParams) view.getLayoutParams();
    GridLayoutManager gridLayoutManager = (GridLayoutManager) parent.getLayoutManager();
    float spanSize = layoutParams.getSpanSize();
    float totalSpanSize = gridLayoutManager.getSpanCount();

    float n = totalSpanSize / spanSize; // num columns
    float c = layoutParams.getSpanIndex() / spanSize; // column index

    float leftPadding = padding * ((n - c) / n);
