在重新循环视图中设置来自大数据的有限数据

我只需要在RecyclerView中设置四个来自API的数据。来自API的数据是动态的,如果有4个以上的数据,那么最后一个数据应该隐藏自己,最近的数据应该出现在顶部。我已经研究过了,但找不到合适的解决方案。

我的适配器

public class EventRecyclerAdapter extends RecyclerView.Adapter<EventRecyclerAdapter.MyViewHolder> {
Context context;
private ArrayList<String> start;
private AdapterView.OnItemClickListener listener;
private ArrayList<String> desc;
private ArrayList<EventData>data;


public EventRecyclerAdapter(Context context, ArrayList<EventData> data) {
    this.context = context;
    this.data = data;
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.content_events, parent, false);

    return new EventRecyclerAdapter.MyViewHolder(itemView);


}

@Override
public void onBindViewHolder(EventRecyclerAdapter.MyViewHolder holder, int position) {
    holder.start.setText(data.get(position).getStartDate());

    holder.des.setText(Html.fromHtml(data.get(position).getName()));
}


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


public class MyViewHolder extends RecyclerView.ViewHolder {
    private TextView start, des, viewall,name;

    private CardView cardView;


    public MyViewHolder(View itemView) {
        super(itemView);

        start = (TextView) itemView.findViewById(R.id.startdate);

        des = (TextView) itemView.findViewById(R.id.description);

        viewall = (TextView) itemView.findViewById(R.id.viewall);




    }

}

}

我将数据设置如下

  private void initEventRecycler() {
    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
    eventR.setLayoutManager(mLayoutManager);
    eventR.setItemAnimator(new DefaultItemAnimator());
    eventR.setNestedScrollingEnabled(false);
    eventRecyclerAdapter = new EventRecyclerAdapter(MainActivity.this, events);
    eventR.setAdapter(eventRecyclerAdapter);

}
