每次我点击ListView，点击的项目就会出现在安卓系统的顶端

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this)); // 设置线性布局管理器
recyclerView.setAdapter(adapter); // 设置适配器

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    // 数据集合
    private List<String> data;

    // 构造方法
    public MyAdapter(List<String> data) {
        this.data = data;
    }

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

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

    // 获取数据集合大小
    @Override
    public int getItemCount() {
        return data.size();
    }

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

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

<TextView
    android:id="@+id/textView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="16dp" />
