My layout :

    <com.marshalchen.ultimaterecyclerview.UltimateRecyclerView
        android:id="@+id/ultimate_recycler_view"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        app:recyclerviewEmptyView="@layout/empty_view"
        app:recyclerviewScrollbars="vertical" />

My Adapter : public class GridVideoAdapter extends UltimateGridLayoutAdapter<VideoModel, GridVideoAdapter.HolderGirdCell> { .... public void clear() { removeAll(); } .... }

My Code :

GridVideoAdapter mAdapter = null;
....
....
public void onInitView() {
        mAdapter = new GridVideoAdapter(new ArrayList<VideoModel>());
        mAdapter.setAdapterActionListener(this);

        mGridLayoutManager = new BasicGridLayoutManager(getContext(), columns, mAdapter);
        ultimateRecyclerView.setLayoutManager(mGridLayoutManager);
        ultimateRecyclerView.setHasFixedSize(true);
        ultimateRecyclerView.setDefaultOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                pageNumber = 1;
                requestGetData();
            }
        });
        // setting load more Recycler View
        ultimateRecyclerView.reenableLoadmore();
        ultimateRecyclerView.setOnLoadMoreListener(new UltimateRecyclerView.OnLoadMoreListener() {
            @Override
            public void loadMore(int itemsCount, int maxLastVisiblePosition) {
                requestGetData();
            }
        });

        ultimateRecyclerView.setAdapter(mAdapter);
        requestGetData();
}

    void requestGetData() {
        // check page number
        if (pageNumber < 1)
            pageNumber = 1;

        RPC.requestGetVideoAtHome(type, pageNumber, new APIResponseListener() {
            @Override
            public void onError(String message) {
                stopAnimLoading();
                DialogUtil.showMessageBox(mContext, message);
            }

            @Override
            public void onSuccess(Object results) {
                stopAnimLoading();
                if (ultimateRecyclerView == null)
                    return;
                ultimateRecyclerView.setRefreshing(false);
                // parse data
                List<VideoJSON> listData = (List<VideoJSON>) results;

                // check end data
                if (listData == null || listData.isEmpty())
                    return;

                // check first get data
                if (pageNumber == 1)
                    mAdapter.clear();

                // update data to view
                pageNumber++;
                updateData(listData);
            }
        });
    }

i think u have put ultimateRecyclerView.reenableLoadmore(); at the beginning and this is not advised.
