public RemoteViews getViewAt(int position) {

    WidgetItem item = mWidgetItems.get(position);
    // We construct a remote views item based on our widget item xml file, and set the
    // text based on the position.

    SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(mContext);
    String theme = settings.getString("choixtheme", "default");

    if (theme.equals("default")) {
        rv = new RemoteViews(mContext.getPackageName(), R.layout.widget_item_default);
    }

    if (item.urlImage != "") {
            URL url = new URL(urlImage);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            myBitmap = BitmapFactory.decodeStream(input);   
    }       

    // Return the remote views object.
    return rv;
}
