Android开发实现ListView部分布局监听的方法

// 适配器
public class OrAdapter extends BaseAdapter {
  @Override
  public int getCount() {
   return dataMap.size();
  }
  @Override
  public Object getItem(int position) {
   return position;
  }
  @Override
  public long getItemId(int position) {
   return position;
  }
  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
   ViewHolder viewHolder = null;
   if (convertView == null) {
    viewHolder = new ViewHolder();
    convertView = getActivity().getLayoutInflater().inflate(
      R.layout.activity_order_item, null);
    initViewHolder(convertView, viewHolder, position);
   } else {
    viewHolder = (ViewHolder) convertView.getTag();
   }
   refreshViewHolder(position, viewHolder);
   return convertView;
  }
  private String getTag(String orderId, String instrument) {
   StringBuilder sb = new StringBuilder();
   sb.append(orderId).append(";").append(instrument);
   return sb.toString();
  }
  private void refreshViewHolder(int position, ViewHolder viewHolder) {
   // ------------------为了防止item被复用------------------
   viewHolder.modeifyorder.setTag(getTag(orderid, instrument));
  }
  private void initViewHolder(View convertView, ViewHolder viewHolder,
    final int position) {
   viewHolder.modeifyorder = (RelativeLayout) convertView
     .findViewById(R.id.modeifyorder);
   viewHolder.modeifyorder.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
     int isman = (Integer) dataMap.get(position).get("ismanual");
     int isprice = (Integer) dataMap.get(position).get(
       "ispricereached");
      String tag = v.getTag().toString();
      String tagVec[] = tag.split(";");
      long orderId = Long.parseLong(tagVec[0]);
      String instStr = tagVec[1];
    }
   });
   convertView.setTag(viewHolder);
  }
  private class ViewHolder {
   TextView orderid;
   RelativeLayout modeifyorder;
  }
}
