报的异常如下：

The specified child already has a parent. You must call removeView() on the child's parent first.

代码如下：

protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		//缓存目录
		cache=new File(Environment.getExternalStorageDirectory(),"cache");
		if(!cache.exists()){
			cache.mkdirs();
		}
		
		//上页传下来的查询内容
		Intent intent = new Intent();
		intent = getIntent();
		result = intent.getStringExtra("result");
		listView = (ListView)findViewById(R.id.listView);
		listView.setAdapter(new BookInfoAdapter(QueryResultActivity.this,getData(),R.layout.view_list_item,cache));  
	
        setContentView(listView);  
	}

public class BookInfoAdapter extends BaseAdapter {

	private List<Map<String, Object>> data;
	private int viewListItem;
	private File cache;
	LayoutInflater layoutInflater;

	public BookInfoAdapter(Context context, List<Map<String, Object>> data,
			int viewListItem, File cache) {
		this.data = data;
		this.viewListItem = viewListItem;
		this.cache = cache;
		// 布局
		layoutInflater = (LayoutInflater) context
				.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

	}

	/**
	 * 得到数据的总数
	 * 
	 */
	@Override
	public int getCount() {
		return data.size();
	}

	/**
	 * 根据数据的索引得到集合中的对应的数据
	 * 
	 */
	@Override
	public Object getItem(int arg0) {

		return data.get(arg0);
	}

	@Override
	public long getItemId(int position) {

		return position;
	}

	/**
	 * position 显示条目对应集合的索引值 convertView 对第一屏进行缓存
	 */
	@Override
	public View getView(int position, View convertView, ViewGroup parent){

		ImageView imageView = null;
		TextView title_textView = null;
		TextView price_textView = null;
		TextView saleprice_textView = null;
		// 第一屏的时候没有缓存
		if (convertView == null) {
			// resource viewListItem条目ID,即把条赋值给对象
			convertView = layoutInflater.inflate(viewListItem, null);
			// 创建条目时，先把各控件找到，否则每次去找耗性能
			imageView = (ImageView) convertView.findViewById(R.id.imageView);
			title_textView = (TextView) convertView.findViewById(R.id.title);
			price_textView = (TextView) convertView.findViewById(R.id.price);
			saleprice_textView = (TextView) convertView
					.findViewById(R.id.saleprice);

			convertView.setTag(new DataWrapper(imageView, title_textView,
					price_textView, saleprice_textView));
		} else {
			DataWrapper dataWrapper = (DataWrapper) convertView.getTag();
			imageView = dataWrapper.imageView;
			title_textView = dataWrapper.title_textView;
			price_textView = dataWrapper.price_textView;
			saleprice_textView = dataWrapper.saleprice_textView;
		}

		title_textView.setText(data.get(position).get("title").toString());
		price_textView.setText(data.get(position).get("price").toString());
		saleprice_textView.setText(data.get(position).get("saleprice")
				.toString());
		try {
			asyncImageLoad(imageView, data.get(position).get("imgurl").toString());
		} catch (Exception e) {
			e.printStackTrace();
		}

		return convertView;
	}

看错误应该是报错的view，本身已经在一个布局里（很可能某个xml里）了，在代码又被添加到另外一个布局。
