如何使用 kotlin 上的 firebase 实时数据库对数据进行分页？

Question

mydatabase= FirebaseDatabase.getInstance("https://words-on-wallpaper-e3ae4-default-rtdb.europe-west1.firebasedatabase.app") database2=mydatabase.getReference("Control").child(auth.currentUser.. :uid+"1") database.addValueEventListener(object : ValueEventListener {

                    override fun onDataChange(snapshot: DataSnapshot) {

                        for (data in snapshot.children) {
                            val image = data.child("url2").value.toString()
                            val name = data.child("langname").value.toString()
                            val childname = data.child("childname").value.toString()
                            val uuid = data.child("id").value.toString()
                            val model = imagemodel(image, name, childname, uuid)
                            arrayList.add(model)
                            key= data.key.toString()


                        }
                        adapters.setItems(arrayList)
                        binding.idRLWallpapers.adapter = ImageAdp(arrayList)
                        adapters.notifyDataSetChanged()
                        binding.idPBLoading.visibility = View.GONE
                        mIsLoading=false
                    }
