Why does it refer to TextView and how to fix it?

Question

Java

Implemented the list. Everything worked.
I wanted to add a preview and then I got an error:

Fragment code:

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    ViewHolder holder = null;

    if (convertView == null) {

        LayoutInflater vi = (LayoutInflater)getSystemService( Context.LAYOUT_INFLATER_SERVICE);
        convertView = vi.inflate(R.layout.person_info, null);

        holder = new ViewHolder();
        holder.name = (TextView) convertView.findViewById(R.id.name);

        holder.preview = (ImageView) convertView.findViewById(R.id.preview);    //  Error

        convertView.setTag(holder);

    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    Persons person = personsList.get(position);
    holder.name.setText(person.getName());
    holder.tracks.setText(person.getTracks());
    holder.albums.setText(person.getAlbums());
    holder.genres.setText(person.getGenres());
    //  holder.preview.setText(person.getGenres());     //  The temporary line

    return convertView;
}

Googling did not find anything sensible - some other methods of implementation.
In general, help, please, kind people.

Answer 1

Apparently, you declared the preview as a TextView in the holder, but it should be as an ImageView. Apparently.

Answer 2

what is holder.preview for you?
In the view you have R.id.preview as described?

Answer 3

The type in the holder does not match the type of the assigned view. Preview is your text view
