Changing the number of columns in recyclerView for each row

I need to make a recyclerView that have two different items and one is the header and the other is the sub item, but to the header I need to use all the width screen and to the sub item I need just 1/4 of the screen.

Basically what I want is that:

---

                        Header

SubItem - SubItem - SubItem - SubItem

SubItem - SubItem

                        Header

SubItem - SubItem

                        Header

SubItem - SubItem - SubItem - SubItem

---

So how I can change the numbers of column according the item in the recyclerView adapter ?
