android - 如何在单个 recyclerView 中设置两个不同的适配器？

Question

我正在显示数据列表。默认情况下，我使用 FirebaseRecyclerPagingAdapter 显示数据，因为我的数据列表很大。我也有搜索选项，当用户提交任何查询时，我会在我的 firebase realtime-database 中搜索结果，在这种情况下，我使用 FirebaseRecyclerAdapter 来显示我的结果。默认情况下，我得到了预期的结果，但是当搜索任何内容时，我没有得到任何输出。是否可以将不同的适配器设置为单个回收器 View ？这是我的代码

private FirebaseRecyclerPagingAdapter<BookLight, BookViewHolder> mAdapter;
private FirebaseRecyclerAdapter<BookLight,BookViewHolder> mAdapterNopage;
private static final String ALL_TYPE="all";


@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
recyclerView = view.findViewById(R.id.recyclerviewid_grp);
        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new LinearLayoutManager(this.getActivity()));

        loadData(ALL_TYPE);

        return view;
    }

private void loadData(String queryBook){

        Query query;
        if(queryBook.equals(ALL_TYPE)){
          query=FirebaseDatabase.getInstance().getReference()
                    .child("GroupMembersBooks")
                    .child(groupDetails.getGroupID())
                    .child("books");
        mAdapter = new FirebaseRecyclerPagingAdapter<BookLight, BookViewHolder>(options) {
      //other stuffs 
      recyclerView.setAdapter(mAdapter);
      };
   }
    else{
            Log.e(TAG, "loadData: "+queryBook);
            query=FirebaseDatabase.getInstance().getReference()
                    .child("GroupMembersBooks")
                    .child(groupDetails.getGroupID())
                    .child("books")
                    .orderByChild("bookName")
                    .startAt(queryBook);
         mAdapterNopage = new FirebaseRecyclerAdapter<BookLight, BookViewHolder>(options) {
     //other stuffs
     };
    recyclerView.setAdapter(mAdapterNopage)
   }
 }

    @Override
    public void onCreateOptionsMenu(Menu menu,MenuInflater menuInflater) {
        menuInflater.inflate(R.menu.group_timeline_menu,menu);
        SearchManager searchManager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);
        searchView = (SearchView) menu.findItem(R.id.action_book_search).getActionView();
        searchView.setSearchableInfo(searchManager
                .getSearchableInfo(getActivity().getComponentName()));
        searchView.setMaxWidth(Integer.MAX_VALUE);

        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                loadData(query);
                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                return false;
            }
        });

        super.onCreateOptionsMenu(menu,menuInflater);
    }

使用swapAdapter

recyclerView.swapAdapter(yourAdapter, false)
