解决方案
我编辑了自己的code检查，并尝试
holder.addfriend =（ImageView的）convertView.findViewById（R.id.addfriend_after_searchs）;
holder.addfriend.setTag（位置）;
holder.city =（TextView中）convertView.findViewById（R.id.serach_city）; convertView.setTag（保持器）;
}其他{
支架=（ViewHolder）convertView.getTag（）;
} holder.addfriend.setTag（位置）;
holder.addfriend.setOnClickListener（新View.OnClickListener（）{
@覆盖
公共无效的onClick（查看视图）{
INT POSI =（整数）view.getTag（）; frindsids = listData.get（POSI）获得（TAG_FRIENDID）;
的System.out.println（HWIHC ID+ frindsids）;
}
}）; holder.txtproname.setText（listData.get（位置）获得（TAGs_NAME））;
holder.city.setText（listData.get（位置）获得（TAGs_CITY））;
aQuery.id(holder.propics).image(listData.get(position).get(TAGs_IMAGES),true,true,0,R.drawable.male); //图片参数：1：内存缓存，2：文件缓存，3：目标宽度，4：备用图片
返回convertView;
}
类ViewHolder {
ImageView的propics;
TextView的txtproname，市;
TextView的txtproid;
TextView的txtprofilecast;
TextView的txtprofileage;
TextView的txtprofileplace;
公共ImageView的addfriend;
} }

MY adapter
public class CustomAdapterAccept extends BaseAdapter{
private Context context;
private ArrayList<HashMap<String,String>> listData;
private AQuery aQuery;
private String TAGs_NAME="user_fname";
private String TAG_FRIENDID="user_id";
private String TAGs_IMAGES="user_pic";
private String TAGs_CITY="user_city";
public CustomAdapterAccept(Context context,ArrayList<HashMap<String,String>> listData) {
this.context = context;
this.listData=listData;
aQuery = new AQuery(this.context);
}
@Override
public int getCount() {
return listData.size();
}
@Override
public Object getItem(int position) {
return listData.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView( final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.list_item_balloonationsearch, null);
holder.propics = (ImageView) convertView.findViewById(R.id.list_item_ballonationsearch_propic);
holder.txtproname = (TextView) convertView.findViewById(R.id.list_item_ballonationsearch_username);
holder.addfriend=(ImageView) convertView.findViewById(R.id.addfriend_after_searchs);
holder.city=(TextView) convertView.findViewById(R.id.serach_city);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
holder.addfriend.setTag(position);
holder.addfriend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
final int position = (int) view.getTag();
frindsids=listData.get(position).get(TAG_FRIENDID);
System.out.println("HWIHC ID"+frindsids);
}
});
holder.txtproname.setText(listData.get(position).get(TAGs_NAME));
holder.city.setText(listData.get(position).get(TAGs_CITY));
aQuery.id(holder.propics).image(listData.get(position).get(TAGs_IMAGES),true,true,0,R.drawable.male);
// image parameter : 1 : memory cache,2:file cache,3:target width,4:fallback image
return convertView;
}
class ViewHolder{
ImageView propics;
TextView txtproname,city;
TextView txtproid;
TextView txtprofilecast;
TextView txtprofileage;
TextView txtprofileplace;
public ImageView addfriend;
}
}
解决方案
I have edited your code check it and try
holder.addfriend=(ImageView) convertView.findViewById(R.id.addfriend_after_searchs);
holder.addfriend.setTag(position);
holder.city=(TextView) convertView.findViewById(R.id.serach_city);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
holder.addfriend.setTag(position);
holder.addfriend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
int posi = (Integer) view.getTag();
frindsids=listData.get(posi).get(TAG_FRIENDID);
System.out.println("HWIHC ID"+frindsids);
}
});
holder.txtproname.setText(listData.get(position).get(TAGs_NAME));
holder.city.setText(listData.get(position).get(TAGs_CITY));
aQuery.id(holder.propics).image(listData.get(position).get(TAGs_IMAGES),true,true,0,R.drawable.male);
// image parameter : 1 : memory cache,2:file cache,3:target width,4:fallback image
return convertView;
}
class ViewHolder{
ImageView propics;
TextView txtproname,city;
TextView txtproid;
TextView txtprofilecast;
TextView txtprofileage;
TextView txtprofileplace;
public ImageView addfriend;
}
}
