在recyclerview中通过ID获取LinearLayout会导致NullPointerException错误

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    public static class ViewHolder extends RecyclerView.ViewHolder {
        public LinearLayout linearLayout;

        public ViewHolder(View itemView) {

        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) {
        // 使用holder.linearLayout进行操作
    }

    @Override
    public int getItemCount() {
        // 返回Item数量
    }
}
