그래서 LinearLayoutManager 를 사용하여 평소와 같이, 조각 탭에서 내 RecyclerView을했고 나 또한 끝없는 스크롤 ScrollListener에 사용할 난에RecyclerView에서 LinearLayoutManager를 얻는 방법 ..?
public override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
mLayoutManager = new LinearLayoutManager(Context);
}
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View row = inflater.Inflate(Resource.Layout.Fragment3, container, false);
RecyclerView mRecyclerView = row.FindViewById<RecyclerView>(Resource.Id.recyclerView);
mRecyclerView.SetLayoutManager(mLayoutManager);
var scrollListener = new scroll(mLayoutManager);
mRecyclerView.AddOnScrollListener(scrollListener);
mRecyclerView.SetAdapter(mAdapter);
}
전대 아래와 같이 변수 LinearLayoutManagerOnCreate 방법을 경우 문제는 상단이 제대로 실행하지만 탭을 이동 또는 오류가 나타납니다 조각을 이동하지만이 솔루션을 찾을 경우 교체 mRecyclerView.SetLayoutManager(mLayoutManager);
에 : mRecyclerView.SetLayoutManager(new LinearLayoutManager(Context));
하지만 끝없는 스크롤, 내 질문은 작동하지 않기 때문에 내가
var scrollListener = new scroll(mLayoutManager);
에 사용해야하는 하나 LinearLayout입니다 ... ??
