LWUIT HtmlComponent 内存不足异常

Question

我想在 LWUIT 表单屏幕上显示来自 Rss 文件的图像和描述 这是我的代码：

HTMLComponent com=new HTMLComponent();
com.setBodyText(detailNews.getDescription());
form2.addComponent(com);

代替 *detailNews.getDescription()*，在循环中形成一个Rss URL的字符串是

<p><img border="1" align="left" width="150" vspace="2" hspace="2" height="159" src="/tmdbuserfiles/Prithvi2_launch1(3).jpg" alt="Prithvi II, ballistic missile, DRDO, armed forces,Chandipur, Balasore district, Odisha State" />The Strategic Forces 
Command of the armed forces successfully flight-tested the surface-to-surface Prithvi II missile from Chandipur in Balasore </P>

如果我执行，我将面临应用程序意外退出，因为它耗尽了内存异常

如果您不需要显示图像，请从 html 字符串中删除 img 标签。

String description = detailNews.getDescription();
StringBuffer newDescription = new StringBuffer();
int imgIndex = description.indexOf("<img");

newDescription.append(description.substring(0, imgIndex));
imgIndex = description.indexOf(">", imgIndex + 1);
newDescription.append(description.substring(imgIndex + 1));
description = newDescription.toString();
com.setBodyText(description);
