How to load all items in recyclerView at once?

I'm trying to inflate all items in RecyclerView, My code is not working on devices below API 24, here is my code.

This is my PreCachingLayoutManager class which extends LinearLayoutManager. 

    public class PreCachingLayoutManager extends LinearLayoutManager {
        private static final int DEFAULT_EXTRA_LAYOUT_SPACE = 800;
        private int extraLayoutSpace = -1;
        private Context context;

        public PreCachingLayoutManager(Context context) {
            super(context);
            this.context = context;
        }

        public PreCachingLayoutManager(Context context, int extraLayoutSpace) {
            super(context);
            this.context = context;
            this.extraLayoutSpace = extraLayoutSpace;
        }

        public PreCachingLayoutManager(Context context, int orientation, boolean reverseLayout) {
            super(context, orientation, reverseLayout);
            this.context = context;
        }

        public void setExtraLayoutSpace(int extraLayoutSpace) {
            this.extraLayoutSpace = extraLayoutSpace;
        }

        @Override
        protected int getExtraLayoutSpace(RecyclerView.State state) {
            if (extraLayoutSpace > 0) {
                return extraLayoutSpace;
            }
            return DEFAULT_EXTRA_LAYOUT_SPACE;
        }
    }

This is my activity code

 dealsImagesRecyclerView = 
 findViewById(R.id.dealsImagesRecyclerView);
    layoutManager = new
            PreCachingLayoutManager(this);
    layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
    layoutManager.setExtraLayoutSpace(deviceHeight);
    layoutManager.setItemPrefetchEnabled(true);
    dealsImagesRecyclerView.setLayoutManager(layoutManager);

RecycleView is created to optimize the load, to not inflate unnecessary itens.

If you wanna inflate all itens, maybe you should use listview.
