                    }

                    @NonNull
                    @Override
                    public PostsViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
                        View view = LayoutInflater.from(ViewGroup.getContext()).inflate(R.layout.all_posts_layout,ViewGroup, false);
public PostsViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
                        View view = LayoutInflater.from(ViewGroup.getContext()).inflate(R.layout.all_posts_layout ,ViewGroup, false);
                        PostsViewHolder viewHolder = new PostsViewHolder(view);
                        return viewHolder;


                    }
                };
    }
} ```
