Images were Shuffled when scrolling a ListView with a ViewHolder

Question

My problem is connected when the user scrolls the ListView. I looked around and saw numerous examples of \'listview lazy image\', has also watched the video of the Google IO

Used as base the example on the blog of Android.

http://android-developers.blogspot.com/2010/07/multithreading-for-performance.html

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

    ViewHolder viewHolder = new ViewHolder();
    if(convertView == null){
        convertView = _inflate.inflate(R.layout.layout_list, null);
        viewHolder.text = (TextView) convertView.findViewById(R.id.title);
        viewHolder.owner = (TextView) convertView.findViewById(R.id.owner);
        viewHolder.image = (ImageView) convertView.findViewById(R.id.thumb);
        convertView.setTag(viewHolder);
    }else{
        viewHolder = (ViewHolder) convertView.getTag();
    }

    HashMap item = (HashMap) getItem(position);

    viewHolder.text.setText( item.get("poiName").toString() );
    viewHolder.owner.setText( item.get("owner").toString() );
    viewHolder.image.setTag(item.get("thumbs"));
    imageDowload.download(item.get("thumbs"), viewHolder.image);


    return convertView;
}

is now working, thanks.
