use of android.support.v7.widget.RecyclerView.Recycler in project GestureViews by alexvasilkov.

the class EndlessRecyclerAdapter method loadNextItemsIfNeeded.

private void loadNextItemsIfNeeded(RecyclerView recyclerView) {
    if (!isLoading && !isError) {
        View lastVisibleChild = recyclerView.getChildAt(recyclerView.getChildCount() - 1);

        int total = getItemCount();
        if (lastVisiblePos >= total - loadingOffset) {
            // We need to use runnable, since recycler view does not like when we are notifying
            // about changes during scroll callback.
            recyclerView.post(new Runnable() {

                @Override
