Question

我在解析后从Rss文件中获取HtmlString。我想删除所有的html标签，并且只需要在我的Form上显示纯文本，为此我已经引用了LWUIT HtmlComponent Class并使用了下面的代码：

    private void displayCompleteNewsScreen(News detailNews) {
        html.removeAll();
        form2.removeAll();
        form2.repaint();
        form2.addCommand(m_backCommand);
        form2.addCommandListener(new ActionListener() {

            public void actionPerformed(ActionEvent ae) {
                form1.show();
            }
        });
    String content= detailNews.getDescription();
    html.setPreferredSize(new Dimension(300,300));
    html.setHTML(content, null, null, false);
    form2.addComponent(html);
    form2.show();
}

我能够在我的LWUITform上成功显示文本，但是我每次在表单上显示文本时都会抛出以下异常

Exception1：

注意：我的HtmlString不会包含任何图片和src标签

任何人都可以帮助我......

Answer 1

HTML代码中似乎存在解析错误。它是包含实际HTML标记，正文等的完整HTML集吗？
