Expandable List View Adapter Getview() Repeats Position

My ExpandableListView's adapter repeats the position of View and Images when I scroll below is my code. I used it without View holder and with view holder in both cases I face this

Solution 1:

Don't pick view by tag

use this

public View getGroupView(int groupPosition, boolean isExpanded,
                         View convertView, ViewGroup parent) {

    Viewview= convertView;
    StringgroupName= (String) getGroup(groupPosition);

    LayoutInflaterinf= (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = inf.inflate(R.layout.group_item, null);
        holder = newViewHolder();

        holder.arrowImage = (ImageView) view.findViewById(R.id.imageView1);
        holder.groupName = (TextView) view.findViewById(R.id.laptop);
        holder.groupName.setTypeface(null, Typeface.BOLD);
        holder.groupName.setText(groupName);
        setImageView(holder.arrowImage, groupPosition);
        view.setTag(holder);

    return view;

}

public ImageView getImageView(int position) {
    return images[position];
}

publicvoidsetImageView(ImageView image, int position) {
    images[position] = image;
}

staticclassViewHolder {
    ImageView arrowImage;
    TextView groupName;
}

this will prevent image repetition and consider every view as a new view
