RecyclerView.Adapter 원하지 않는 공간

Question

그래서 나는 (관광과 쇼핑)과 (내 최고 이미지와 관광) 사이의 불필요한 공간을 제거 할.

관광, 쇼핑, 음식 & dink, hotes는 모두 내 어댑터입니다. 하지만 내 첫 번째 항목에이 "공간"문제가 있습니다. 여기

항목에 대한 내 XML입니다

<com.inthessaloniki.cityguide.view.SelectorRelativeLayout

은 찾을 수가 없습니다

문제가있는 곳. 미리 감사드립니다. 이 PoiListAdapter#setItemMargins(View view, int position)의 구현에

Answer 1

봐는 때마다이 방법 public void onBindViewHolder(RecyclerView.ViewHolder viewHolder, int position)은 public void onBindViewHolder(RecyclerView.ViewHolder viewHolder, int position) 한 번 호출 할 수 없습니다 것을 고려 setItemMargins

if(position<mGridSpanCount) 
{ 
    height += marginTop; 
} 

내에서 호출됩니다. 위의 코드는 호출 될 때마다 값을 추가합니다.
