java-me - 如何仅为 BorderLayout.CENTER 设置滚动？

Question

我有顶栏、列表和底栏。

this.setLayout(new BorderLayout());
this.addComponent(BorderLayout.NORTH, bottomBar);
this.addComponent(BorderLayout.CENTER, list);
this.addComponent(BorderLayout.SOUTH, bottomBar);

List很长。bottomBar 和 bottomBar 是隐藏的。滚动是在全屏上。如何进行滚动仅适用于BorderLayout.CENTER. bottomBar 和 bottomBar 将可见。

Answer 1

禁用Form. 例如这样做，

Form f = new Form();
f.setLayout(new BorderLayout());
f.setScrollable(false);
f.addComponent(BorderLayout.NORTH, new Label("Top bar"));
f.addComponent(BorderLayout.CENTER, list);
f.addComponent(BorderLayout.SOUTH, new Label("Bottom bar"));
f.show();
