使用FirebaseAdapter的搜索栏实现

Question

我正在尝试实现搜索栏菜单项。我知道如何使用arrayadapter做到这一点，但对如何使用FirebaseAdapter对其感到困惑。基本上我的代码是带有片段的选项卡布局。我曾尝试在Internet上找到它，但实现方式非常模糊或已使用其他方法完成了。  我的片段代码看起来像这样：

public ChatsFragment() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    mMainView = inflater.inflate(R.layout.fragment_chats, container, false);

   ...
    // Inflate the layout for this fragment
    return mMainView;
}


@Override
public void onStart() {
    super.onStart();


    if(mConvDatabase != null ) {
        Query conversationQuery = mConvDatabase.orderByChild("timestamp");

        FirebaseRecyclerAdapter<Conv, ConvViewHolder> firebaseConvAdapter = new FirebaseRecyclerAdapter<Conv, ConvViewHolder>(
                Conv.class,
                R.layout.users_single_layout,
                ConvViewHolder.class,
                conversationQuery
        ) {

            @Override
            protected void onDataChanged() {
                if(getItemCount() == 0){
                    text.setText("No Chats Available");
                }
                else{
                    text.setText("");
                }
            }


            @Override
            protected void populateViewHolder(final ConvViewHolder convViewHolder, final Conv conv, int i) {


                final String list_user_id = getRef(i).getKey();

                Query lastMessageQuery = mMessageDatabase.child(list_user_id).limitToLast(1);

                lastMessageQuery.addChildEventListener(new ChildEventListener() {
                    @Override
                    public void onChildAdded(DataSnapshot dataSnapshot, String s) {

                        String data = dataSnapshot.child("message").getValue().toString();
                        if (data.contains("firebase")) {
                            convViewHolder.setMessage("Storage", conv.isSeen());
                        } else {
                            convViewHolder.setMessage(data, conv.isSeen());
                        }

                    }

         ...

                });


    if(list_user_id != null) {
        mUsersDatabase.child(list_user_id).addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {


            final String userName = dataSnapshot.child("name").getValue().toString();
            String userThumb = dataSnapshot.child("thumb_image").getValue().toString();

            if (dataSnapshot.hasChild("online")) {

                String userOnline = dataSnapshot.child("online").getValue().toString();
                convViewHolder.setUserOnline(userOnline);

            }

            convViewHolder.setName(userName);
            convViewHolder.setUserImage(userThumb, getContext());


            convViewHolder.mView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {


                    Intent chatIntent = new Intent(getContext(), ChatActivity.class);
                    chatIntent.putExtra("user_id", list_user_id);
                    chatIntent.putExtra("user_name", userName);
                    startActivity(chatIntent);

                }
            });
        }




    @Override
    public void onCancelled(DatabaseError databaseError) {

        }
    });
}
            }
        };

        mConvList.setAdapter(firebaseConvAdapter);
    }
}

@Override
public void onCreateOptionsMenu(@NonNull Menu menu, @NonNull MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.chats_menu,menu);
    MenuItem menuItem = menu.findItem(R.id.main_search_bar);
    SearchView searchView = (SearchView) menuItem.getActionView();
    searchView.setQueryHint("Type here to Search");
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            fire
            return false;
        }

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


}

public static class ConvViewHolder extends RecyclerView.ViewHolder {

    View mView;

    public ConvViewHolder(View itemView) {
        super(itemView);

        mView = itemView;

    }
  ...
  }

任何人都可以指导我如何使用FirebaseAdapter实现onQueryTextSubmit。 谢谢。
