In XML:->
<yourPackageName.CircularNetworkImageView android:layout_width="60dp" android:layout_height="60dp" android:id="@+id/userImgClass" />

In Activity:->
 CircularNetworkImageView thumbnail = ((CircularNetworkImageView) convertView.findViewById(R.id.main_activity_listview_item_thumbnail));

if you don't use your package name in XML u'll get ClassCastException
