在ViewHolder的点击事件中更新RecyclerView适配器的解决方法如下：

1. 首先，在RecyclerView的适配器类中定义一个接口，用于处理ViewHolder的点击事件。

public interface OnItemClickListener {
    void onItemClick(int position);
}

2. 在ViewHolder中设置点击事件，并在点击事件中调用接口的回调方法。

public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    private TextView textView;
    private OnItemClickListener listener;

    public MyViewHolder(View itemView, OnItemClickListener listener) {
        super(itemView);
        textView = itemView.findViewById(R.id.text_view);
        this.listener = listener;
        itemView.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if (listener != null) {
            int position = getAdapterPosition();
            if (position != RecyclerView.NO_POSITION) {
                listener.onItemClick(position);
            }
        }
    }
}

3. 在RecyclerView的适配器类中实现接口，并在接口的回调方法中更新数据集并刷新RecyclerView。

public class MyAdapter extends RecyclerView.Adapter {
    private List data;
    private OnItemClickListener listener;

    public MyAdapter(List data, OnItemClickListener listener) {
        this.data = data;
        this.listener = listener;
    }

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

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

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

    public void updateData(List newData) {
        data = newData;
        notifyDataSetChanged();
    }
}

4. 在Activity或Fragment中设置RecyclerView的适配器和点击事件处理逻辑。

public class MainActivity extends AppCompatActivity implements OnItemClickListener {
    private RecyclerView recyclerView;
    private MyAdapter adapter;

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

        recyclerView = findViewById(R.id.recycler_view);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));

        List data = new ArrayList<>();
        // 添加数据到data

        adapter = new MyAdapter(data, this);
        recyclerView.setAdapter(adapter);
    }

    @Override
    public void onItemClick(int position) {
        // 处理点击事件，例如更新数据集
        List newData = new ArrayList<>();
        // 更新数据到newData

        adapter.updateData(newData);
    }
}

在点击ViewHolder时，会触发接口的回调方法，从而在Activity或Fragment中处理点击事件并更新RecyclerView适配器。
