Hi Vani,

I  Have gone through your code and problem is in image fetching
portion. Fetching images from server and display part you do it in
android asynctask task.

Fetching part you do in  doInBackground method and  in onPostExecute
add that image into view. Always you will remember .. for all server
interaction you have to use  asynctask task or thread or handler
otherwise ANR( android not responding) error will come

 Hi friends,

 In the LazyAdapter class i am sending an object which consists of an
 arraylist , while scrolling the listview it gets stuck and shows the
 infamous ANR dialog.
 This is the listview in xml

   ListView
             android:id=@+id/android:list
             android:layout_width=fill_parent
             android:layout_height=wrap_content
             android:layout_margin=5dip
              android:background=@android:color/transparent
             android:cacheColorHint=#
             android:divider=@android:color/darker_gray

             android:scrollbars=none
             android:fastScrollEnabled=true
             
 Below is thegetView method
 @Override
     public View getView(final int position, View convertView, ViewGroup
 parent) {

         String name = ;

         ViewHolder holder;

         if (convertView == null) {
             convertView = mInflater.inflate(R.layout.commentitem, null);

             holder = new ViewHolder();
             holder.reviewText = (TextView) convertView
                     .findViewById(R.id.reviewText);

             holder.fbImage = (ImageView)
 convertView.findViewById(R.id.fbImage);

             convertView.setTag(holder);
         } else {

             holder = (ViewHolder) convertView.getTag();
         }

         String profilePictureURL = http://graph.facebook.com/;
                 + cList.getData().get(position).getFbid() + /picture;

         if (cList.getData().get(position).getName() == null) {
             name = ;
         } else {
             name = cList.getData().get(position).getName() +  says ;
         }

         holder.reviewText.setText( + name
                 + cList.getData().get(position).getComment());

         try {
             Bitmap bitmap = BitmapFactory.decodeStream((InputStream) new
 URL(
                     profilePictureURL).getContent());
             holder.fbImage.setImageBitmap(Utility.getRoundedCornerBitmap(
                     bitmap, 10));
         } catch (MalformedURLException e) {
             e.printStackTrace();
         } catch (IOException e) {
             e.printStackTrace();
         }

         return convertView;
     }

 How to resolve this??
