如何在android长点击时从自定义列表视图中删除项目？

// 自定义列表适配器
public class CustomListAdapter extends BaseAdapter {
    private List<String> itemList;
    private Context context;

    public CustomListAdapter(Context context, List<String> 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(final 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.itemTextView = convertView.findViewById(R.id.itemTextView);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        String item = itemList.get(position);
        holder.itemTextView.setText(item);

        // 设置长按监听器
        convertView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                showDeleteDialog(position); // 弹出删除对话框
                return true;
            }
        });

        return convertView;
    }

    // 删除对话框
    private void showDeleteDialog(final int position) {
        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setTitle("删除项目");
        builder.setMessage("确定要删除该项目吗？");
        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                itemList.remove(position); // 从数据源中删除项目
                notifyDataSetChanged(); // 更新列表视图
            }
        });
        builder.setNegativeButton("取消", null);
        builder.show();
    }

    private static class ViewHolder {
        TextView itemTextView;
    }
}
