如何从PagedListAdapter筛选数据？

Question

我想像使用类过滤PagedListAdapter
一样过滤我的RecyclerView.AdapterFilter

public class CustomFilter extends Filter {

    private CustomFilter(RecyclerViewAdapter mAdapter) {
        super();
    }

    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        filteredList.clear();
        final FilterResults results = new FilterResults();
        // do filter stuff
        return results;
    }

    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
    }

}

谁能指导我？
