layoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
            @Override
            public int getSpanSize(int position) {
                int type=mAdapter.getItemViewType(position);
                if (type == "view holder type name")
                    return 2;
                else
                    return 1;

Answer 2

You can change the layout manager to GridLayoutManager and define the "span size" for the header, for example, if you want the grid with 2 columns, the header should have span size 2 and the children span size 1:

    GridLayoutManager glm = new GridLayoutManager(getContext(), 2);
    glm.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
        @Override
        public int getSpanSize(int position) {
            switch(getTypeForPosition(position)) {
                case HEADER:
                    return 2;
                default:
                    return 1;
            }
        }
    });
    recyclerView.setLayoutManager(glm);

There is a full example of expandable grid with headers here using this library.
