如何隐藏某些内容以不显示给 recyclerview

Question

I am working on code which I copied from somewhere as a learner. The app displays data in recyclerview, this data is coming from firebase database. All is working well, the data is displaying nicely in recyclerview.

My worry now is: i have added another recyclerview in the same activity. So now I have two recyclerviews with these IDs: recyclerview and recyclerview2. They are in one activity but in different layouts, and only one layout is visible at a time, and by clicking the button it hides one layout and shows another. For now the recyclerviews are showing same data.

What i want now is this: In these recyclerviews I have a TextView which changes text time by time. It sometimes shows this text 'CLOSED'. So i want all the data which has a textview which shows 'CLOSED' to be shown on recyclerview2 and will be unavailable on the first recyclerview.

So my issue is to make the data not to display on recyclerview (first one) if the textview is showing 'CLOSED' and i want the recyclerview2 to show only data which has a textview showing this text 'CLOSED'

I do not know where to start from. Below is my MainActivity.java where i want the code to be added.

public class MainActivity extends AppCompatActivity {
    private RecyclerView recyclerView, recyclerView2;
    private DatabaseReference mDatabase, vDatabase;
    private FirebaseAuth mAuth;
    private FirebaseAuth.AuthStateListener mAuthListener;

List<Blogzone> openedZones = new ArrayList<>();
List<Blogzone> closedZones = new ArrayList<>();

openedZones.addAll(mDatabase.stream().filter(zone -> zone.isOpened()).collect(Collectors.toList()));
closedZones.addAll(mDatabase.stream().filter(zone -> zone.isClosed()).collect(Collectors.toList()));

FirebaseRecyclerAdapter<Blogzone, BlogzoneViewHolder> FBRAopened = new FirebaseRecyclerAdapter<Blogzone, BlogzoneViewHolder>(
    Blogzone.class,
    R.layout.card_items,
    BlogzoneViewHolder.class,
    openedZones
) {
    ...
}
        
FirebaseRecyclerAdapter<Blogzone, BlogzoneViewHolder> FBRAclosed = new FirebaseRecyclerAdapter<Blogzone, BlogzoneViewHolder>(
