CoordinatorLayout에서 Recyclerview 확장을 방지하는 방법

Question

coordinatorlayout으로 시차 헤더를 만들고 싶습니다. 코디네이터 레이아웃에 리사이클 뷰를 추가했습니다. 그것은 작동합니다. 그러나 recyclerview는 모든 데이터를로드하지만 내 데이터 목록을 페이지로 나눕니다. 마지막 항목이 스크롤 될 때마다 다음 페이지를로드하려고합니다. 그러나 처음에는 모든 데이터를로드합니다.

으로 고정 된 높이를 Recyclerview로 설정하거나, Match_Parent attr을 RecyclerView로 설정 한 경우 NestedScrollView의 FrameLayout을 설정해야합니다.
