Yes you can update listview with dynamic_data.

Just look at this tutorial ...

And I recommend you use Picasa for images ...

Picasso is easy to use. 

  @Override public zero getView (integer position, seeviewview, ViewGroup parent) in your adapter {ImageViewView = (ImageView) ConvertViewFind WBID (RID.ranking_prod_pic); Picasso.with (reference) .load (URL) .into (see); // URL Image URL / / If you want you can resize image / * with Picasso (context) .load (url). Reset (50, 50) .centercrop () .INTO (View) * /}
