    public View getView(int position, View convertView, ViewGroup parent) {            final int cc = position;            ViewHolder holder = null;            if (convertView == null) {                holder = new ViewHolder();                convertView = mInflater.inflate(R.layout.itemrow, null);                holder.tagcolor = (ImageView) convertView.findViewById(R.id.itemrowiamge);                holder.itemname = (TextView) convertView.findViewById(R.id.itemrowtext);                holder.cb = (CheckBox) convertView.findViewById(R.id.itemrowcb);                convertView.setTag(holder);            } else {                holder = (ViewHolder) convertView.getTag();            }             //擷取ViewHolder中所填入的資料            holder.tagcolor.setBackgroundResource((Integer) itemList.get(position).get("IMG"));            holder.itemname.setText((String) itemList.get(position).get("ITEMNAME"));            holder.ckd = (String) itemList.get(position).get("CHECKED");             //單個項目中的CheckBox的按鍵監聽函數            holder.cb.setOnClickListener(new View.OnClickListener() {                public void onClick(View v) {                    setC(cc);//當被按下後調用函數改變狀態                }            });            if (holder.ckd.equals("t"))                holder.cb.setChecked(true);            else                holder.cb.setChecked(false);            return convertView;        }

設一個holder類

import android.widget.CheckBox;import android.widget.ImageView;import android.widget.TextView; //ViewHolder類用以儲存每一條項目所需的資料public class ViewHolder {    public ImageView tagcolor;//單條項目中的圖片    public TextView itemname;//單條項目中的文本    public CheckBox cb;//單條項目中的CheckBox    public String ckd;//單條項目中用以標識CheckBox狀態的字串變數}

即可。
