How to add sections for checked and unchecked items in recyclerview?

I have a list of tasks in recyclerview. Each task item has a check box to show if the task is completed or pending.

Now I want to show two sections in my list. One for checked items and another for unchecked items.

I have gone through this library to add the sections.

But how can I divide the items in list on the basis of they are checked or not? Also I want to add the task into another section if checked or unchecked , i.e onClick.

If task is unchecked, and if I check it, it should get added to the completed section and vise versa.

I have a recyclerview now with swipe layout. Following is the adapter.

adapetr:

 public class IAdapter extends RecyclerSwipeAdapter<IAdapter.ItemViewHolder> , SectionedRecyclerViewAdapter<IAdapter.ItemViewHolder> {

    public ArrayList<Task> items;
    Context conext;
    public int _mId;

    List<Task> itemsPendingRemoval = new ArrayList<>();

    public IAdapter(Context context, ArrayList<Task> item) {
        this.conext=context;
       this.items=item;
    }

    @Override
    public int getSectionCount() {
        return 2;
    }

    @Override
    public int getItemCount(int section) {
        return items.size();

    }

    public static class ItemViewHolder extends RecyclerView.ViewHolder {
        Task task;
        CheckBox cb;
        SwipeLayout swipeLayout;
        TaskTableHelper taskTableHelper;
        ItemViewHolder(final View itemView) {
            super(itemView);

            taskTableHelper= new TaskTableHelper(itemView.getContext());
            swipeLayout = (SwipeLayout) itemView.findViewById(R.id.swipe);
            cb = (CheckBox) itemView.findViewById(R.id.checkbox);

        }
    }

    @Override
    public void onBindViewHolder(final ItemViewHolder itemViewHolder,final int i) {

        itemViewHolder.cb.setText(items.get(i).getTitle());

        itemViewHolder.task = items.get(i);

        int taskId = itemViewHolder.task.getId();

        itemViewHolder.task = itemViewHolder.taskTableHelper.getTask(taskId);

        int status = itemViewHolder.task.getStatus();

        if(status == 0)
        {
            itemViewHolder.cb.setTextColor(Color.WHITE);
        }

        else {

            itemViewHolder.cb.setChecked(true);

            itemViewHolder.cb.setTextColor(Color.parseColor("#B0BEC5"));

        }


       itemViewHolder.cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                if (isChecked) {

                    itemViewHolder.cb.setTextColor(Color.parseColor("#B0BEC5"));

                    itemViewHolder.task.setStatus(1);

                    itemViewHolder.taskTableHelper.updateStatus(itemViewHolder.task);

                }
                else

                {

                    itemViewHolder.cb.setTextColor(Color.WHITE);

                    itemViewHolder.task.setStatus(0);

                    itemViewHolder.taskTableHelper.updateStatus(itemViewHolder.task);

                }

            }

        });

Can anyone help please? Thank you..
