viewholder的另一种写法

private final static class {
    TextView name;
    TextView age;
    TextView sex;
}

public class {
	
	public static <T extends View>T get(View view,int id){
		SparseArray<View> viewHolder = (SparseArray<View>)view.getTag();
		if(viewHolder == null){
			viewHolder = new SparseArray<View>();
			view.setTag(viewHolder);
		}
		View childView = viewHolder.get(id);
		if(childView == null){
			childView = view.findViewById(id);
			viewHolder.put(id,childView);
		}
		return (T)childView;
	}
}

public View getView(int position,View convertView,ViewGroup parent){
	if(convertView == null){
		convertView = mInflater.inflate(R.layout.item_hotel_list,parent,false);
	}
	ImageView img = ViewHolder.get(convertView,R.id.item_hotel_list_img);
	return convertView;
}
