Question

왜 내 listItem이 이상한 방식으로 렌더링되는지 알 수 없습니다. 나는 제약 조건을 점검하고 모든 것이 잘된 것처럼 보입니다. 여기

레이아웃에 대한 내 XML입니다 : : 여기

컨테이너입니다 저는 여기에 런타임 대 디스플레이시에지고있어 무엇의 사진입니다 XML :

나는 또한 컨테이너를 v (단편)을 포함하는 활동으로 보아라. 내 어댑터와 RecyclerView에 대한 ViewHolder 클래스를 게시 할 수 있습니다

하지만 아마 필요가 없습니다 나에게 의미

Answer 1

뭔가가 있다는 것입니다 : 그것은 할 수 있지만, 여기에 활동하는 경우 나도 몰라 RecyclerView는 고정 된 높이와 너비가 없습니다. 이를 바탕으로

는

<android.support.v7.widget.RecyclerView 
    android:id="@+id/customer_recycler_view" 
    android:layout_width="0dp" 
    android:layout_height="380dp" 

, 당신이

android:height="?android:attr/listPreferredItemHeight"
