在recyclerView制作的图像下面创建下一个和上一个

Question

我已经在recyclerView的帮助下制作了imageSlider。现在，我想在其下方放置button，即将下一个和上一个工作作为其名称。我已经用XML完成，但是在代码中却感到困惑。请帮助我。

这是主要活动：

public class MainActivity extends AppCompatActivity  {
public RecyclerView recyclerView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        recyclerView = findViewById(R.id.rv);
        LinearLayoutManager layoutManager = new LinearLayoutManager(this);
        layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);

        recyclerView.setLayoutManager(layoutManager);

        SnapHelper snapHelper = new PagerSnapHelper();
        snapHelper.attachToRecyclerView(recyclerView);

        List<Word> wordList = new ArrayList<>();

        wordList.add(new Word(R.drawable.da, null));
        wordList.add(new Word(R.drawable.ic_launcher_background, null));
        wordList.add(new Word(R.drawable.oq, null));

        RecyclerViewAdapter adapter = new RecyclerViewAdapter (this);
        recyclerView.setAdapter(adapter);
        adapter.addItems(wordList);
    }
}
