黑莓手机如何处理横向显示的请求？

1. Extend net.rim.device.api.ui.container.MainScreen.

2. In protected void sublayout(int width, int height) call Display.getOrientation() and compare it with the previous value. When a change in orientation is detected, discard all cached screen size calculations and call invalidate(). And, of course, call super.sublayout at the end.
