How to make posts load partial and cache the posts using firebase in Android studio?

Question

I have made a newsfeed with FirebaseRecyciclerView but the problem is they are loading all at once and the scrolling is very slow and lagging. I want to add partial loading and caching. Like Facebook, Twitter, Instagram etc. I have tried with Volley but I cant figure it out. Can someone with more knowledge tell me what is the best solution for my problem.

I have tried with this answer but got no results Firebase load data dynamically on scrolling

private void DisplayAllUsersPosts()
{
    Query SortPostsInDescendingOrder = PostsRef.orderByChild("counter");

    FirebaseRecyclerAdapter<Posts, PostsViewHolder> firebaseRecyclerAdapter =
            new FirebaseRecyclerAdapter<Posts, PostsViewHolder>
                    (
                            Posts.class,
                            R.layout.all_posts_layout,
                            PostsViewHolder.class,
                            SortPostsInDescendingOrder
                    )
            {
                @Override
                protected void populateViewHolder(PostsViewHolder viewHolder, Posts model, int position)
                {
                    final String PostKey = getRef(position).getKey();

                    viewHolder.setFullname(model.getFullname());
                    viewHolder.setTime(model.getTime());
                    viewHolder.setDate(model.getDate());
                    viewHolder.setDescription(model.getDescription());
                    viewHolder.setUser_thumb_image(getApplicationContext(), model.getUser_thumb_image());
                    viewHolder.setPostimage(getApplicationContext(), model.getPostimage());

                    viewHolder.setLikeButtonStatus(PostKey);

                    viewHolder.mView.setOnClickListener(new View.OnClickListener() {
