如何根据条件更改listview中的图像

public class CustomAdapter extends BaseAdapter {
    private Context context;
    private List<Item> itemList;

    public CustomAdapter(Context context, List<Item> itemList) {
        this.context = context;
        this.itemList = itemList;
    }

    @Override
    public int getCount() {
        return itemList.size();
    }

    @Override
    public Object getItem(int position) {
        return itemList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;

        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
            holder = new ViewHolder();
            holder.imageView = convertView.findViewById(R.id.imageView);
            holder.textView = convertView.findViewById(R.id.textView);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        Item item = itemList.get(position);
        holder.textView.setText(item.getName());

        // 根据条件设置图像
        if (item.getCondition()) {
            holder.imageView.setImageResource(R.drawable.image1);
        } else {
            holder.imageView.setImageResource(R.drawable.image2);
        }

        return convertView;
    }

    private static class ViewHolder {
        ImageView imageView;
        TextView textView;
    }
}

ListView listView = findViewById(R.id.listView);
List<Item> itemList = new ArrayList<>();
// 添加数据项到itemList
CustomAdapter adapter = new CustomAdapter(this, itemList);
listView.setAdapter(adapter);
