ExpandableRecyclerViewに2つの子を追加する方法

Question

私はExpandableRecyclerViewを使ってリストを作成しましたが、このリストの2番目のChiledを4に追加します。 同じリストに別の子を追加する方法。

private Activity activity; 

    public RecyclerAdapterDemo(Activity activity, List<? extends ExpandableGroup> groups) { 
     super(groups); 
     this.activity = activity; 
    } 

    @Override 
    public OSViewHolder onCreateGroupViewHolder(ViewGroup parent, int viewType) { 
     LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
     View view = inflater.inflate(R.layout.group_view_holder, parent, false); 

     return new OSViewHolder(view); 
    } 

    @Override 
    public PhoneViewHolder onCreateChildViewHolder(ViewGroup parent, final int viewType) { 
     LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
     View view = inflater.inflate(R.layout.child_view_holder, parent, false); 

     return new PhoneViewHolder(view); 
    } 

    @Override 
    public void onBindChildViewHolder(PhoneViewHolder holder, int flatPosition, ExpandableGroup group, int childIndex) { 
     final Phone phone = ((MobileOS)group).getItems().get(childIndex); 
     holder.onBind(phone,group); 
    } 

    @Override 
    public void onBindGroupViewHolder(OSViewHolder holder, int flatPosition, ExpandableGroup group) { 
     holder.setGroupName(group); 
    }
