如何修改动态列表的图像？

动态列表中包含一个 imageview 和一个 textview。我想在点击的时候改变指定位置的图像，如何实现？

public class CoverLetterAdaptor extends BaseAdapter{    String[] coverLetterItems;    Context context;        private LayoutInflater mInflater;       int htwt;public CoverLetterAdaptor(Context contextint htint wt String[] coverLetterTitle){    this.context = context;    this.coverLetterItems = coverLetterTitle ;              this.ht = ht;    this.wt = wt;    mInflater = LayoutInflater.from(context);}public int getCount() {    return coverLetterItems.length;}public Object getItem(int position) {    return position;}public long getItemId(int position) {    return position;}public View getView( final int position View convertView ViewGroup parent) {    ViewHolder holder;    if (convertView == null)    {        convertView = mInflater.inflate(R.layout.coverletteradaptor null);             holder = new ViewHolder();        holder.coverLetterTxt = (TextView) convertView.findViewById(R.id.coverLetterAdaptorTxt);        holder.bgImageCCAdaptor = (ImageView)convertView.findViewById(R.id.bgimageCoverLetter);        holder.bgimageCoverLetter = (ImageView)convertView.findViewById(R.id.bgimageCoverLetterr);        holder.bgimageCoverLetter.setLayoutParams(new RelativeLayout.LayoutParams(wt ht/7));               convertView.setTag(holder);     }    else                        holder = (ViewHolder) convertView.getTag();    holder.coverLetterTxt.setText(coverLetterItems[position]);    return convertView;} static class ViewHolder{    TextView coverLetterTxt;            ImageView bgImageCCAdaptor;    ImageView bgimageCoverLetter;}}
