listview中的按钮响应时如何获取holder中某一组件的引用或是itemid

[yaoyue1019]

		@Override
		public View getView(int position, View convertView, ViewGroup parent) {
			// TODO Auto-generated method stub
			ViewHolder holder = null;
			if (convertView == null) {
				holder = new ViewHolder();
				convertView = mInflater.inflate(
						R.layout.config_listview_activity, null);
				holder.title = (TextView) convertView
						.findViewById(R.id.textTitle);
				holder.detail = (TextView) convertView
						.findViewById(R.id.textDetail);
				holder.viewBtn = (Button) convertView
						.findViewById(R.id.button_config);
				convertView.setTag(holder);

			} else {
				holder = (ViewHolder) convertView.getTag();
			}

			holder.title.setText((String) listData.get(position).get("title"));
			holder.detail
					.setText((String) listData.get(position).get("detail"));

			holder.viewBtn.setOnClickListener(new View.OnClickListener() {
				@Override
				public void onClick(View v) {
					Toast.makeText(FenceConfig.this,
							"asdfasdf",
							Toast.LENGTH_SHORT).show();
				}
			});

			return convertView;
		}

在

			holder.viewBtn.setOnClickListener(new View.OnClickListener() {
				@Override
				public void onClick(View v) {
					Toast.makeText(FenceConfig.this,
							"asdfasdf",
							Toast.LENGTH_SHORT).show();
				}
			});

中 如果需要获得对holder的引用 应该怎么写 我尝试了很多方法 都没办法正确的引用到holder

因为ViewHolder的作用域受限于getView函数 在初始化完成之后就无法获得直接的引用 而在按钮响应点击时 又没法获得当前点击的是哪一个item 十分烦恼
