I am facing a problem to hide `RecyclerView`. From Last 2 night's I am looking for the solution but I have failed to find it.

I am using firebase `recycleradapter` to show value in `recyclerview`. When ever someone click the `viewholderitem` i save his `Uid` under the `datasnapshot` key. 

So to show the value if `datasnapshot` don't have the `uid` key show the value in `recyclerview`. If the `datasnapshot` have the `uid` key don't show his data . everything works fine . But i want to hide the `recyclerview` and show a `textview` when every `datasnapshot` have the uid key and there is nothing to show in the `recyclerview`. My problem is in the last line . I can't hide the `recyclerview` and how the `textview`. 

```
FirebaseRecyclerOptions options = new FirebaseRecyclerOptions.Builder<ViewsAdapter>()
                .setQuery(ViewsRef,ViewsAdapter.class)
                .build();

        adapter = new FirebaseRecyclerAdapter<ViewsAdapter, ViewsAdapterHolder>(options) {

            @Override
            protected void onBindViewHolder(@NonNull final ViewsAdapterHolder holder, int position, @NonNull ViewsAdapter model) {
                String userIds = getRef(position).getKey();
                assert userIds != null;
                ViewsRef.child(userIds).addValueEventListener(new ValueEventListener() {
                    @Override
                    public void onDataChange(@NonNull DataSnapshot dataSnapshot) {

                        if (dataSnapshot.hasChild(Uid)){
                            Long date = dataSnapshot.child(Uid).getValue(Long.class);

                            assert date != null;
                            int dat = date.intValue();

                            if (dat!=Date){
                                recyclerView.removeAllViews();
                                dataSnapshot.child(Uid).getRef().setValue(null);
                                adapter.startListening();

                            }

                            ViewGroup.LayoutParams layoutParams =holder.itemView.getLayoutParams();
                            layoutParams.width= ViewGroup.LayoutParams.MATCH_PARENT;
                            layoutParams.height= 0;
                            holder.itemView.setLayoutParams(layoutParams);

                        }else {

                            //get the data from child and show in recyclerview

                            holder.button.setOnClickListener(new View.OnClickListener() {
                                @Override
                                public void onClick(View v) {

                        }

                    }

                    @Override
                    public void onCancelled(@NonNull DatabaseError databaseError) {

                    }
                });

            }

            @NonNull
            @Override
            public ViewsAdapterHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
                View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.viewsview,viewGroup,false);
                return new ViewsAdapterHolder(view);
            }

        };

        recyclerView.setAdapter(adapter);

```
