The Activity class does not have aOnBindSwipeContentHolder method to override.
Within Telerik, ListViewAdapter and ListViewDataSourceAdapter do:
onBindSwipeContentHolder
public void onBindSwipeContentHolder(ListViewHolder holder, int position)
Called by RadListView to display the swipe content behind an item at the specified position. This method should update the contents of the com.telerik.widget.list.ListViewHolder#itemView to reflect the swipe content behind the item at the given position.
In order to achieve this we will need to override the ListViewAdapter's onBindSwipeContentHolder(ListViewHolder holder, int position).
I believe you have that method in the wrong class, you should be in your custom list adapter.
