单击按钮以使用RecyclerView适配器位置

// RecyclerView适配器
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> data;

    public MyAdapter(List<String> data) {
        this.data = data;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        // 创建视图，并将其绑定到ViewHolder上
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        // 将数据绑定到ViewHolder的视图上
        holder.textView.setText(data.get(position));
    }

    @Override
    public int getItemCount() {
        // 返回数据集合的大小
        return data.size();
    }

    // 自定义ViewHolder
    public static class ViewHolder extends RecyclerView.ViewHolder {
        public TextView textView;

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

// 使用RecyclerView和适配器
public class MainActivity extends AppCompatActivity {
    private RecyclerView recyclerView;
    private MyAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 初始化RecyclerView和适配器
        recyclerView = findViewById(R.id.recycler_view);
        adapter = new MyAdapter(getData());

        // 设置布局管理器和适配器
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerView.setAdapter(adapter);
    }

    // 模拟数据
    private List<String> getData() {
        List<String> data = new ArrayList<>();
        data.add("Item 1");
        data.add("Item 2");
        data.add("Item 3");
        return data;
    }
}
