单击recyclerview项后，将recyclerview位置的数据保存到firebase

Question

我是Android的初学者。我想使用回收者视图位置将数据保存到Firebase。例如，我是“ A”用户，当我单击回收者视图项（它是“ B”用户）时，我得到“ B”的用户UID并保存“ A”用户的数据，例如“ kullanici”，“ sifre”（参见示例）：

final RecyclerView recyclerView2 = findViewById(R.id.recyclerView);
recyclerView2.addOnItemTouchListener(
    new RecyclerItemClickListener(getApplicationContext(), recyclerView2 ,new RecyclerItemClickListener.OnItemClickListener() {
        @Override public void onItemClick(View view, int position) {

            Toast.makeText(getApplicationContext(),"Long Click"+ epostaList.get(position),Toast.LENGTH_SHORT).show();


            String value = (String) recyclerView2.getVerticalScrollbarPosition(position);


            databaseReference = FirebaseDatabase.getInstance().getReference().child("users");
            databaseReference.child(resgisterpage.cinsiyyet.toString()).child("connections").child("yeps").child(resgisterpage.userId).setValue(true);


            // FirebaseUser currentFirebaseUser = FirebaseAuth.getInstance().getCurrentUser() ;
            // Toast.makeText(context, "" + currentFirebaseUser.getUid(), Toast.LENGTH_SHORT).show();


            //Toast.makeText(context,"Kayıt Başarılı.",Toast.LENGTH_LONG).show();
        }

        @Override public void onLongItemClick(View view, int position) {
            // do whatever


        }
    })
);
