你使用LWUIT库更多JScrollPanes？然后你应该添加LWUIT标签。 – Meier

我认为这个链接可以帮助你。 http://stackoverflow.com/questions/17144349/lwuit-textarea-scroll-issue –

要使TextArea文本可滚动，您必须使用滚动窗格。

您需要做的是这样

JScrollPane scrollPane = new JScrollPane(textarea);

看到http://docs.oracle.com/javase/7/docs/api/javax/swing/JScrollPane.html
