Answer 1

Break it into pieces -

1. Get the url of the image from div tag
2. Show that image in the list view

Now for "1", you can use jsoup and parse the url of the image

For "2", first add image view to your list view xml Then create an asynctask, pass image url to it and reference of image view and set its value in onPostExecute. You said that website sets image dynamically, in that case every time on the get view method of list view adapter, you have to parse the webpage. Although this sounds very inefficient and intensive, but I don't think there is any other way. If somehow you can know when is the image going to change, then you can do this processing on that event. Anyway, this is the code of the asynctask to download the image from a url and set it to image view

public class ThumbnailDownloader extends AsyncTask<String, Integer, Bitmap>{

ImageView imview;
Context ctx;

public ThumbnailDownloader(Context c, ImageView imview){
    this.imview = imview;
    this.ctx = c;
}

@Override
protected Bitmap doInBackground(String... urls) {
        try{
            HttpURLConnection connection = (HttpURLConnection)new URL(getThumbUrl(urls[0])).openConnection();

            connection.connect();
            InputStream input= connection.getInputStream();
            Bitmap bitmap = BitmapFactory.decodeStream(input);
        return bitmap;

        }
        catch (Exception f) {
            // TODO Auto-generated catch block
            f.printStackTrace();
        }
    return null;
}

@Override
protected void onPostExecute(Bitmap result) {
    // TODO Auto-generated method stub
    super.onPostExecute(result);
    if(result != null && imview!=null){
        imview.setImageBitmap(result);
    }
}

public String getThumbUrl(String videoUrl){
    return "http://img.youtube.com/vi/"+videoUrl+"/default.jpg";
}
}

The getThumbUrl method you have to modify according to your need. The one specified above is used to download youtube video thumbnails.
