If you just want to display HTML, you can see android.text.Html .
You will need to use a custom adapter so that you can control the display of the list, so when displaying the contents, you can do something like:
lblRSSContent.setText(Html.fromHtml(rssItem.getContent()));
I noticed that the provided rss feed also contains images. Therefore, you should also look into the Html.ImageGetter so that you can process and display images.
