 public class CustomRecyclerViewScrollListener extends    RecyclerView.OnScrollListener {
    int visibleCount = 0;
    int totalItemCount = 0;

        super.onScrolled(recyclerView, dx, dy);

        visibleCount = llm.getChildCount();
        totalItemCount = llm.getItemCount();
        pastVisibleItems = llm.findFirstVisibleItemPosition();
        lastVisibleItem=llm.findLastVisibleItemPosition();
        if (!isLoading && !dataFinished && list.size() % 10 == 0) {
            if ((visibleCount + pastVisibleItems) >= totalItemCount) {
                    isLoading = true;
                    loadMore();
                    adapter.showViewHolderFooter();

        }

private int firstVisibleItem, visibleItemCount,totalItemCount,pastVisiblesItems;
private boolean loading = true;

    reyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
                @Override
                public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                    if (dy > 0) //check for scroll down
                    {
                        visibleItemCount = mLayoutManager.getChildCount();
                        totalItemCount = mLayoutManager.getItemCount();
                        pastVisiblesItems = mLayoutManager.findFirstVisibleItemPosition();

                        if (loading) {
                            if ((visibleItemCount + pastVisiblesItems) >= totalItemCount) {
                                loading = false;
                                expandapleInt++;

                              //Your operation
                        }
                         }
                    }
                }
            });

In my code for every operation set loading = true; in your code set isLoading to false before every load starts
