Java – Android: reverse the position of recyclerview

I'm setting up a recyclerview like a list. I want to have a button at the bottom of the list to add more views when clicking. I think the easier way is to take position 0 as the first one at the bottom and increase the position to the top, so I can add views when clicking the view in position 0

This is my adapter:

public class AddEventsAdapter extends RecyclerView.Adapter<AddEventsAdapter.ViewHolder> {

   public List<String> items = new ArrayList<>();



    public void addItem(String name) {
        notifyItemInserted(items.size() - 1);
        items.add(name);

    }

    public void removeItem(int position) {
        items.remove(position);
        notifyItemRemoved(position);
        notifyItemRangeChanged(position,items.size());
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View view = inflater.inflate(R.layout.add_event_item,parent,false);

        return new ViewHolder(view);
    }

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

    @Override
    public void onBindViewHolder(ViewHolder holder,int position) {
        holder.setData(position);
        holder.eventName.setText(i + "");
        if(position == 0)
        {
            holder.theLayout.setBackgroundColor(Color.parseColor("#7F9099"));
            holder.eventName.setText("Add");
        }

    }


    static int i;
    class ViewHolder extends RecyclerView.ViewHolder{

        public TextView eventName;
        public RelativeLayout theLayout;

        public ViewHolder(final View itemView) {
            super(itemView);
            eventName = (TextView)itemView.findViewById(R.id.eventName);
            theLayout = (RelativeLayout)itemView.findViewById(R.id.backgroundevent);

            theLayout.setId(++i);


        }

        public void setData(final int position) {
            theLayout.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    if (position == items.size() - 1) {
                        addItem("");
                    } else {
                        removeItem(position);
                    }
                }
            });
        }


    }


}

You may notice some errors. I have completed this error in the past 10 hours, and I have encountered a logic failure

Solution

It solves the layoutmanager problem through the line addind setReverseLayout(true);
