                       myNewsList.addActionListener(new ActionListener() {
                         public void actionPerformed(ActionEvent ae) {
                        int selectedIndex = myNewsList.getSelectedIndex();
                        if(selectedIndex != -1){
                             newsItem1 = (News)news.elementAt(selectedIndex);
                             Label l=new Label();
                             l.setText(newsItem1.getPubDate());
                             Form detailedForm=new Form();
                             detailedForm.addCommand(m_backCommand);
                             detailedForm.addCommandListener(this);
                             detailedForm.addComponent(l);
                             detailedForm.show();                   
                       }                   

                       }
                    });                  
                    }

     Can you help?

Add action listener to the list. It is called only if you click any item of the list. In that action listener, get the selected item and cast it to the News class object because you added News class objects in the list. From that object, get the unique property like news id. Pass it to another screen with the current form object (form1).

myNewsList = new List(news);
myNewsList.setListCellRenderer(new NewsListRenderer());

myNewsList.addActionListener(new ActionListener() {

     public void actionPerformed(ActionEvent ae) {
           News allNewsClassObjs = (News) myNewsList.getSelectedItem();
           int newsid = allNewsClassObjs.getNewsId(); 
           displayCompleteNewsScreen(form1,newsid);
     }
});
form1.addComponent(myNewsList); 
form1.addCommand(cmdDetails);
form1.setScrollable(true);
form1.setTransitionInAnimator(Transition3D.createRotation(250, true));
form1.show();

With the news id, you can display the related data in another screen. Add back command to it. In the back command, just show the form1 object.

public void displayCompleteNewsScreen(Form form1,int newsid){

// Get the related data and add it to another form object(form2).

form2.addCommand("Back");
form2.addCommandListener(new ActionListener() {

         public void actionPerformed(ActionEvent ae) {
               form1.show();
         }
    });
form2.show();
}

Instead of using

int selectedIndex = myNewsList.getSelectedIndex();
if(selectedIndex != -1){
newsItem1 = (News)news.elementAt(selectedIndex);
}

Use the below code

newsItem1 = (News)myNewsList.getSelectedItem();
