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.

Answer 2

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();
    }

    }
}
