如何在一个适配器中使用两个arrayList？

public class CustomAdapter extends BaseAdapter {
    private ArrayList<String> list1;
    private ArrayList<String> list2;
    private Context context;

    public CustomAdapter(Context context, ArrayList<String> list1, ArrayList<String> list2) {
        this.context = context;
        this.list1 = list1;
        this.list2 = list2;
    }

    @Override
    public int getCount() {
        // 返回适配器中数据项的总数
        return Math.max(list1.size(), list2.size());
    }

    @Override
    public Object getItem(int position) {
        // 返回指定位置的数据项
        if (position < list1.size()) {
            return list1.get(position);
        } else {
            return list2.get(position - list1.size());
        }
    }

    @Override
    public long getItemId(int position) {
        // 返回指定位置的数据项ID
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // 创建或重用视图，并将数据适配到视图中显示
        ViewHolder holder;
        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
            holder = new ViewHolder();
            holder.textView1 = convertView.findViewById(R.id.text_view1);
            holder.textView2 = convertView.findViewById(R.id.text_view2);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        if (position < list1.size()) {
            holder.textView1.setText(list1.get(position));
            holder.textView2.setText("");
        } else {
            holder.textView1.setText("");
            holder.textView2.setText(list2.get(position - list1.size()));
        }

        return convertView;
    }

    private static class ViewHolder {
        TextView textView1;
        TextView textView2;
    }
}
