Attempt to write to field 'int android.support.v7.widget.RecyclerView$ViewHolder.mItemViewType' on a null object reference

[dekaustubh]

 mBookingsList.enableLoadmore();
    mBookingsList.setOnLoadMoreListener(new UltimateRecyclerView.OnLoadMoreListener() {
        @Override
        public void loadMore(int itemsCount, int maxLastVisiblePosition) {

        }
    });

I am getting null pointer exception when I scroll the recycler view.

I am extending it with UltimateViewAdapter<MyViewHolder>

i have made some similar design pattern to work with this mechanism and issued in another library this is the sample code.

[progfiles]

set mBookingsList.enableLoadmore() after add first items range

[jiangecho]

same issue.

@Kaustubh-Deshmukh please check your getViewHolder(), if this method return null, would cause this issue.

I added layout manager this way to fix it:

final ScrollSmoothLineaerLayoutManager mgm = new ScrollSmoothLineaerLayoutManager(this, LinearLayoutManager.VERTICAL, false, 300);
myURecycleRView.setLayoutManager(mgm);
