учаю изображение с URL. Я использую imageview в listview. Я хочу добавить список растровых изображений в каждую строку элемента списка. Я использовал SimpleAdapter, но изображение показывает пустой. Мой код ниже!

 ArrayList<HashMap<String, Bitmap>> mylist = new ArrayList<HashMap<String, Bitmap>>();

    Bundle bundle = this.getIntent().getExtras();
     get = bundle.getString("name");

     try{
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost("http://www.propertyhookup.com/mobile/propertylist.php");
            nameValuePairs = new ArrayList<NameValuePair>(1);
            nameValuePairs.add(new BasicNameValuePair("zipcode", get.trim()));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            is = entity.getContent();

    }catch(Exception e){
            Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
    }

  //convert response to string
    try{
            BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                    sb.append(line + "\n");
            }
            is.close();
            result=sb.toString();
    }catch(Exception e){
            Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
    }
    if(result.length()<= 7){
        Toast.makeText(getApplicationContext(), "No properties for this zipcode or check your zipcode ", Toast.LENGTH_LONG).show();
        //text.setText("No properties for this zipcode or check your zipcode");
    }
    else{
    try{

     jArray = new JSONObject(result);            
    }catch(JSONException e){
        Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
    }

    //JSONObject json = JSONfunctions.getJSONfromURL("http://192.168.1.111/propertyhookup.com/mobile/propertylist.php");

            //HashMap<String, Drawable> map1 = new HashMap<String, Drawable>();

            JSONObject e = earthquakes.getJSONObject(i);
