android firebase realtimedatabase Questions(recycler view, onclick button, remove)

I want the data of item1 to be deleted when the button on item1 is clicked. but mDatabase.getReference("Choicestore").child(String.valueOf(arrayList.get(position))); I don't know what to do with this part.

I want the data of item1 to be deleted when the button on item1 is clicked. and I want the data of item2 to be deleted when the button on item2 is clicked.

@Override
public void onBindViewHolder(@NonNull final ChoicestoreViewHolder holder, final int position) {

    Glide.with(holder.itemView)
            .load(arrayList.get(position).getChoicestore_img())
            .into(holder.choicestore_img);
    holder.choicestore_name.setText("storename : " + arrayList.get(position).getChoicestore_name());
    holder.choicestore_time.setText("opentime : " + arrayList.get(position).getChoicestore_time());
    holder.choicestore_breaktime.setText("breaktime : " +arrayList.get(position).getChoicestore_breaktime());
    holder.choicestore_number.setText("storenumber : " + arrayList.get(position).getChoicestore_number());

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

            mDatabase = FirebaseDatabase.getInstance();
            dataRef = mDatabase.getReference("Choicestore").child(String.valueOf(arrayList.get(position)));

            dataRef.removeValue();

        }
    });
}

I coded using the answers below, but I get this error.

    holder.choicestore_delete.setOnClickListener(new View.OnClickListener(){

        @Override

            final String NAme= arrayList.get(position).getChoicestore_name();


            dataRef.orderByChild("choicestore_name")
                    .equalTo( NAme )
                    .addListenerForSingleValueEvent(new ValueEventListener() {
                        @Override
                        public void onDataChange(DataSnapshot dataSnapshot) {
                            for (DataSnapshot childSnapshot : dataSnapshot.getChildren()) {
                                String clubkey = childSnapshot.getKey();

                                Log.d(TAG, "KEY = " + clubkey );


                                childSnapshot.getRef().removeValue();


                            }

                        }

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

                        }

                    });
        }
    });



}

This is the code where the error occurred.
