i have a working listview with text and want now to add an image with AQuery.
I've changed the XML and added the ImageView element and now want to add load the image by AQuery Till now i used a SpecialAdapter for the TextViews, but i'm struggling what i have to do to get the Image
my code so far, I think i have to do something with the adapter now like
aq.id(R.id.imageView).image(c.getString("URL"), false, false);
, but what exactly?

int colorPos = position % colors.length;
view.setBackgroundColor(colors[colorPos]);
return view;
}
}
Ok, i've fixed it with the Adapter below and it works. Would be nice to get comments for better coding, i'm not sure if i have to do all the stuff in the getView section
