Answer 1

you can override following method in SimpleAdapter:

    @Override
    public void setViewImage(ImageView v, String value) {
        super.setViewImage(v, value);
        URL url;
        try {
            url = new URL(value);
            URLConnection conn = url.openConnection();
            conn.connect();
            InputStream is = conn.getInputStream();
            Bitmap bm = BitmapFactory.decodeStream(is);
            v.setImageBitmap(bm);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

the parameter "String value" is the url in your dataset.

Answer 2

Override the setViewImage in SimpleAdapter and load the image url, in optimized way.

@Override
public void setViewImage(final ImageView v, final String value) {
    new AsyncTask<Void, Integer, InputStream>() {
        @Override
        protected InputStream doInBackground(Void... params) {
            try {
                return new URL(value).openConnection().getInputStream();

            } catch (Exception ex) {
                // handle the exception here
            }
            return null;
        }

        @Override
        protected void onPostExecute(InputStream result) {
            if(result != null) {
                Bitmap bitmap = BitmapFactory.decodeStream(result);
                v.setImageBitmap(bitmap);
            }
        }
    }.execute();        
}
