You can use list renderer to add image and text in single list item.

NewsListRenderer.java

public class NewsListRenderer implements ListCellRenderer {

    private Label lblImage;
    private TextArea textAreaHeadline;

    public Component getListCellRendererComponent(List arg0, Object obj,
            int arg2, boolean isSelected) {

        Container newsContainer = new Container();
        newsContainer.setLayout(new BoxLayout(BoxLayout.X_AXIS));

        News newsListObj = (News) obj;
        Image img = newsListObj.getThumbnail();
        lblImage = new Label(img);
        lblImage.getStyle().setBgTransparency(0);
        lblImage.setTextPosition(Component.BOTTOM);
        newsContainer.addComponent(lblImage);

        textAreaHeadline = new TextArea(3, 25);
        textAreaHeadline.setSelectedStyle(textAreaHeadline.getStyle());
        textAreaHeadline.setText(newsListObj.getHeadLine());
        textAreaHeadline.setEditable(false);
        textAreaHeadline.getStyle().setBorder(null);
        textAreaHeadline.setFocusable(false);
        textAreaHeadline.getStyle().setBgTransparency(0);
        newsContainer.addComponent(textAreaHeadline);
        return newsContainer;
    }

    public Component getListFocusComponent(List arg0) {
        return new Container();
    }
}

Members of News Class:

1) News title - getHeadLine() to retrieve title.

2) News Image - getThumbnail() to retrieve image.

    myNewsList = new List(news);
    myNewsList.setListCellRenderer(new NewsListRenderer());
    form1.addComponent(myNewsList); 
    form1.addCommand(cmdDetails);
    form1.setScrollable(true);
    form1.setTransitionInAnimator(Transition3D.createRotation(250, true));
    form1.show();
