When you use a GridLayoutManager you are able to use setSpanSizeLookup. Here is a snippet from my project which should help to use this method properly:

if (mAdapter == null) {
    final int columnCount = getResources().getInteger(R.integer.numberGridColumns);
    mLayoutManager = new GridLayoutManager(getActivity(), columnCount);
    mLayoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
        @Override
        public int getSpanSize(int position) {
            switch (mAdapter.getItemViewType(position)) {
                case ListAdapter.VIEW_TYPE_ONE_COLUMN:
                    return columnCount;
                case RecipeListAdapter.VIEW_TYPE_FULL_COLUMN:
                default:
                    return 1;
            }
        }
    });
    mRecyclerView.setLayoutManager(mLayoutManager);

    mAdapter = new RecipeListAdapter(mPresenter);
    mRecyclerView.setAdapter(mAdapter);
}
mAdapter.notifyDataSetChanged();
