}

Answer 1

• You might have used inflater in your custom ListAdapter
• In that, not exactly this but something similar, might have been done.
• `if()
  {
  LinearLayout ll = yourInflater.inflate(….); else { ll= (LinearLayout) convertView;}
• In order to get call id do like this:
  `ImageView call = ll.findViewById(r.id.call);

Hope it will help you………..
