@Override 
public void onBindViewHolder(final ViewHolder holder, final int position) { 
   PlaceItem item = list.get(position); 
 
   String name = item.getName() != null ? item.getName() : ""; 
   String description = item.getDescription() != null ? item.getDescription() : ""; 
   String location = item.getAddress() != null ? item.getAddress() : ""; 
   String rating = String.format("%.02f", item.getRating()); 
   String distance = item.getDistance()+"km"; 
   holder.name.setText(name); 
   holder.location.setText(location); 
   holder.description.setText...
