Create a RestaurantHolder

To improve performance and encapsulation, we should move the logic that populates a row from a restaurant into a separate class, one that can cache the TextView and ImageView widgets.
To do this, add the following static inner class to LunchList:
static class RestaurantHolder {
private TextView name=null;
private TextView address=null;
private ImageView icon=null;
RestaurantHolder(View row) {
name=(TextView)row.findViewById(R.id.title);
address=(TextView)row.findViewById(R.id.address);
icon=(ImageView)row.findViewById(R.id.icon);
}
void populateFrom(Restaurant r) {
name.setText(r.getName());
address.setText(r.getAddress());
if (r.getType().equals("sit_down")) {
icon.setImageResource(R.drawable.ball_red);
}
else if (r.getType().equals("take_out")) {
icon.setImageResource(R.drawable.ball_yellow);
}
else {
icon.setImageResource(R.drawable.ball_green);
}
}
}
