如何在recyclerview适配器中填充此数据？

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> mDataList;

    public MyAdapter(List<String> dataList) {
        mDataList = dataList;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        String data = mDataList.get(position);
        holder.textView.setText(data);
    }

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

    public static class ViewHolder extends RecyclerView.ViewHolder {
        TextView textView;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            textView = itemView.findViewById(R.id.text_view);
        }
    }
}

List<String> dataList = new ArrayList<>();
dataList.add("Data 1");
dataList.add("Data 2");
dataList.add("Data 3");

RecyclerView recyclerView = findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
MyAdapter adapter = new MyAdapter(dataList);
recyclerView.setAdapter(adapter);
adapter.notifyDataSetChanged();
