When you put a RecyclerView inside a ScrollView of the same orientation the RecyclerView will extend, inflating and putting out all of his children inside the ScrollView becoming unscrollable. When you drag the view the RecyclerView consumes touch events and the ScrollView won't scroll, unless you disable RecyclerView touch..
