Android ListView优化 怎么省略ViewHolder方法

代码：

public class ViewHolder {    /**     * @param view converView     * @param id 控件的id     * @return 返回<T extends View>     */    public static <T extends View> T get(View view, int id) {        SparseArray<View> viewHolder = (SparseArray<View>) view.getTag();        if (null == viewHolder) {            viewHolder = new SparseArray<View>();            view.setTag(viewHolder);        }        View childView = viewHolder.get(id);        if (null == childView) {            childView = view.findViewById(id);            viewHolder.put(id, childView);        }        return (T) childView;    }}

在Adapter使用：

   @Override    public View getView(int position, View convertView, ViewGroup parent) {        String keyName = getItem(position);        if (null == convertView) {            convertView = inflate(R.layout.layout_comm_custom_search_item, null);        }        TextView searchKeyName = (TextView)ViewHolder.get(convertView, R.id.search_key_name);        searchKeyName.setText(keyName);        return convertView;    }
