    log.d("abcd", "" + lv.getvisibility());     lv.setadapter(adapter);  }  }         please me.      

write below code in getview() have initialized holder.img imageview

 new downloadimagetask(holder.img)             .execute(listdata.get(position).get("img")); 

below asynctask download image , display in imageview

private class downloadimagetask extends asynctask<string, void, bitmap> {           imageview bmimage;            public downloadimagetask(imageview bmimage) {               this.bmimage = bmimage;           }            @override         protected void onpreexecute() {             super.onpreexecute();          }          protected bitmap doinbackground(string... urls) {               string urldisplay = urls[0];               bitmap micon11 = null;               try {                 inputstream in = new java.net.url(urldisplay).openstream();                 micon11 = bitmapfactory.decodestream(in);               } catch (exception e) {                   log.e("error", e.getmessage());                   e.printstacktrace();               }               return micon11;           }            protected void onpostexecute(bitmap result) {               bmimage.setimagebitmap(result);            }         } 

if have small number of items in listview use above code else recommendable use lazylist .
