 * 使用方式：在adapter的getview()中使用,且adapter中不需要申明viewholder

 *  if (convertView == null) {

 *    convertView = LayoutInflater.from(context).inflate(R.layout.xxxadapteritem, parent, false);

 * }

 *  TextView lefttv = ViewHolderUtils.get(convertView, R.id.xxxxx);

           if (viewHolder == null) {

               viewHolder = new SparseArray<View>();

               view.setTag(viewHolder);

           }

           View childView = viewHolder.get(id);

adapter繼承BaseAdapter類在下列方法中使用

@Override
public View getView(int position, View convertView, ViewGroup parent) {

   if(convertView == null) {
      convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_listview_more, null);
   }
   TextView lable= ViewHolderUtils.get(convertView,R.id.label);   //需要設定的item映射出來 
 ........

   return convertView;
}
