в моем приложении у меня есть динамически созданные кнопки (это мои категории), и когда я нажимаю на них, я хочу, чтобы под ними были подкатегории, но они появляются под всеми категориями, взгляните на это фото

ФРАГМЕНТ ЯВА

public View onCreateView(@NonNull final LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment_newfactor,container,false);
        ln = v.findViewById(R.id.itemsContainer);

        dbConnector = new DbConnector(getContext(),null,null,1);
        Cursor c = dbConnector.get().rawQuery("SELECT * FROM categories",null);



        while (c.moveToNext()){

            final int id = c.getInt(c.getColumnIndex("id"));
            String name = c.getString(c.getColumnIndex("name"));

            final View rowView = inflater.inflate(R.layout.field_button, null);
            Button fieldCreator = rowView.findViewById(R.id.fieldCreator);
            fieldContainer = rowView.findViewById(R.id.field_container);
            //fieldCreator.setText(name);
            fieldCreator.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Cursor c = dbConnector.get().rawQuery("SELECT * FROM product WHERE category_id = " + id,null);

                    while (c.moveToNext()){
                        final View rowView = inflater.inflate(R.layout.field, null);
                        fieldContainer.addView(rowView);

                    }


                }
            });

            ln.addView(rowView);

        }




        return v;
    }
