从片段调用viewHolder方法

// 在片段中获取RecyclerView的引用
RecyclerView recyclerView = view.findViewById(R.id.recyclerView);

// 创建适配器并设置给RecyclerView
MyAdapter adapter = new MyAdapter(dataList);
recyclerView.setAdapter(adapter);

// 在适配器中定义ViewHolder类
public class MyViewHolder extends RecyclerView.ViewHolder {
    private TextView textView;

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

    public void setText(String text) {
        textView.setText(text);
    }
}

// 在适配器中调用ViewHolder方法
public class MyAdapter extends RecyclerView.Adapter<MyViewHolder> {
    private List<String> dataList;

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

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

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
        String data = dataList.get(position);
        holder.setText(data);
    }

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