Question

我正在从web xml文件和图像中读取数据。我把图像作为Bitmap bmImg，我把它放在Hashmap中。但我确实知道如何修改我的simpleAdapter函数以在imageView中显示该图像。我被困在这里，我正在做研究项目。有什么建议吗？

这是代码：

NodeList nodes = doc.getElementsByTagName（“product”）; for（int i = 0; i＆lt; nodes.getLength（）; i ++）{

    HashMap<String, Object> map = new HashMap<String, Object>();    

        Element e = (Element)nodes.item(i);
          Bitmap bmImg = null;


           try {

               DefaultHttpClient httpClient = new DefaultHttpClient();
               HttpPost httpPost = new HttpPost("http://licrp.dnsalias.net:8000/iteam/images/" + GetXML.getValue(e, "ImagePath"));
               HttpResponse httpResponse = httpClient.execute(httpPost);
               HttpEntity httpEntity = httpResponse.getEntity();
               BufferedHttpEntity b_entity = new BufferedHttpEntity(httpEntity);
               InputStream input = b_entity.getContent();

               bmImg = BitmapFactory.decodeStream(input);

            } catch (MalformedURLException e1) {

            } catch (IOException e1) {

            } 

        map.put("id", GetXML.getValue(e, "id"));
        //map.put("ProductName", "Product Name:" + GetXML.getValue(e, "ProductName")); Example
        map.put("ProductName", GetXML.getValue(e, "ProductName"));
        map.put("Desc",  GetXML.getValue(e, "Desc"));
        map.put("Price", GetXML.getValue(e, "Price"));
        map.put("ImagePath", bmImg);
        mylist.add(map);            
    }       

    SimpleAdapter adapter = new SimpleAdapter(this, mylist , R.layout.lbsdetailviewmain, 
                    new String[] { "ProductName", "Desc","Price","ImagePath" }, 
                    new int[] { R.id.product_name, R.id.desc , R.id.price,R.id.image1});
    setListAdapter(adapter);
    final ListView lv = getListView();
    lv.setTextFilterEnabled(true);
