我尝试在布局中有多个RecyclerView,但是我遇到了以下错误:“LayoutManager已经附加到RecyclerView”
Java代码如下:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_squad, container, false);
Activity parentActivity = getActivity();
final ObservableScrollView scrollView = (ObservableScrollView) view.findViewById(R.id.squad_scrollview);
final RecyclerView gkRecyclerView = (RecyclerView) view.findViewById(R.id.gk_recycler);
final RecyclerView coachRecyclerView = (RecyclerView) view.findViewById(R.id.coach_recycler);
coachRecyclerView.setAdapter(new SquadRecyclerAdapter(parentActivity, getSquadDummyData(0)));
coachRecyclerView.setLayoutManager(new MyLinearLayoutManager(parentActivity, LinearLayoutManager.VERTICAL, false));
coachRecyclerView.setHasFixedSize(false);
gkRecyclerView.setAdapter(new SquadRecyclerAdapter(parentActivity, getSquadDummyData(1)));
gkRecyclerView.setLayoutManager(new MyLinearLayoutManager(parentActivity, LinearLayoutManager.VERTICAL, false));
gkRecyclerView.setHasFixedSize(false);
scrollView.setTouchInterceptionViewGroup((ViewGroup) parentActivity.findViewById(R.id.container));
if (parentActivity instanceof ObservableScrollViewCallbacks) {
scrollView.setScrollViewCallbacks((ObservableScrollViewCallbacks) parentActivity);
}
return view;
}
XML 布局代码是:

MyLinearLayoutManager是我在网上找到的自定义LinearLayoutManager,旨在解决SDK LinearLayoutManager的wrap-content问题。
我是否可以在单个布局中拥有多个RecyclerView?似乎我不能在一个布局中附加多个LayoutManager。
任何帮助都将非常欢迎 :)
