Check out the RSS reader component that is a part of LWUIT4IO or standard part of Codename One.

You can just place it using the GUI builder to create such an application.

To Develope an Rss Reader Application using LWUIT , we can use the below Code:

RssMidlet:

import com.sun.lwuit.*;
import com.sun.lwuit.animations.Transition3D;
import com.sun.lwuit.events.ActionEvent;
import com.sun.lwuit.events.ActionListener;
import java.util.Vector;
import javax.microedition.midlet.*;

 public class RssMidlet extends MIDlet implements ActionListener {

    private List rssFeedList;
    private Vector rssFeed;
    private Image image;
    private Form form1;

    public RssMidlet() {
        Display.init(this);
        rssFeed = new Vector();
        form1 = new Form();
        form1.setFocus(true);
        form1.addCommandListener(this);
        form1.setScrollableY(true);
        form1.setTransitionInAnimator(Transition3D.createRotation(250, true));
        //Initialize a  List Object with Vector ref rssFeed
        rssFeedList = new List(rssFeed);
        rssFeedList.setRenderer(new NewsListCellRenderer());
        rssFeedList.setFixedSelection(List.FIXED_NONE);
        rssFeedList.setItemGap(0);
        form1.addComponent(rssFeedList);
    }

    public void startApp() {

        String url = "Your Input Rss File Here";
        ParseThread myThread = new ParseThread(this);
        //this will start the second thread
        myThread.getXMLFeed(url);
    }

    public void pauseApp() {
    }

    public void destroyApp(boolean unconditional) {
    }

        public void addNews(RssModel newsItem) {
        rssFeed.addElement(newsItem);

       form1.show();
    }

    }
}
