ListView和Button混合后，获取所点击button在ListView中的position

主要还是在我之前的一片博客http://blog.csdn.net/xinqiqi123/article/details/6458030基础上进行完善，贴上主要代码，大部分和之前一篇差不多
 
public class lvButtonAdapter extends BaseAdapter {
private class ButtonViewHolder {
ImageView appIcon;
TextView appName;
ImageButton buttonClose;
int position;
}
private int mButtonClickPosition;
private ArrayList<HashMap<String, Object>> mAppList;
private LayoutInflater mInflater;
private Context mContext;
private String[] keyString;
private int[] valueViewID;
private ButtonViewHolder holder;

public lvButtonAdapter(Context c, ArrayList<HashMap<String, Object>> appList, int resource, 
String[] from, int[] to) {
mAppList = appList;
mContext = c;
mInflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
keyString = new String[from.length];
valueViewID = new int[to.length];
System.arraycopy(from, 0, keyString, 0, from.length);
System.arraycopy(to, 0, valueViewID, 0, to.length);
}

@Override
public int getCount() {
return mAppList.size();
}

@Override
public Object getItem(int position) {
return mAppList.get(position);
}

@Override
public long getItemId(int position) {
return position;
}

public void removeItem(int position){
mAppList.remove(position);
this.notifyDataSetChanged();
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView != null) {
holder = (buttonViewHolder) convertView.getTag();
} else {
convertView = mInflater.inflate(R.layout.lvitem, null);
holder = new buttonViewHolder();
holder.appIcon = (ImageView)convertView.findViewById(valueViewID[0]);
holder.appName = (TextView)convertView.findViewById(valueViewID[1]);
holder.buttonClose = (ImageButton)convertView.findViewById(valueViewID[2]);
convertView.setTag(holder);
}

holder.position = position;//获取每个item位置
HashMap<String, Object> appInfo = mAppList.get(position);
if (appInfo != null) {
String aname = (String) appInfo.get(keyString[1]);
int mid = (Integer)appInfo.get(keyString[0]);
int bid = (Integer)appInfo.get(keyString[2]);
holder.appName.setText(aname);
holder.appIcon.setImageDrawable(holder.appIcon.getResources().getDrawable(mid));
holder.buttonClose.setImageDrawable(holder.buttonClose.getResources().getDrawable(bid));
holder.buttonClose.setOnClickListener(new lvButtonListener(position));
} 
return convertView;
}

public ButtonViewHolder getViewHolder(View v){
  if (v.getTag() == null){
    return getViewHolder((View) v.getParent());
  }
  return (buttonViewHolder ) v.getTag();
}//注意此方法的使用老外写的
class lvButtonListener implements OnClickListener {
private int position;

lvButtonListener(int pos) {
position = pos;
}

@Override
public void onClick(View v) {
int vid=v.getId();
if (vid == holder.buttonClose.getId()){
ButtonViewHolder holder = getViewHolder(v);
mButtonClickPosition = holder.position;//此处获得所点击button在list中的位置即：position  
removeItem(position);
}
}
}
