黑莓问题显示虚拟键盘并出现空白屏幕

Question

当我显示 VirtualKeyboard 然后在我的屏幕上出现 MainScreen 上方的空白区域时，我遇到了问题。 有什么想法可以避免这个空白？

大概是黑莓操作系统对这家伙的怪异态度吧…… Weird behavior in Blackberry when toggling virtual keyboard between two textboxes

Answer 1

private VerticalFieldManager manBackground;
private NewsList newsList;

问题已解决，使用 onExposed() 方法 ...

protected void onExposed() {
   if (comesfromArticle){ //comes from an article (probably the Virtual Keyboard was showed)...
    manBackground.delete(manBackground.getField(0)); / Delete the manager that contains the list of news (newsList).
    manBackground.add(newsList);//Add again the newslist, so the blank space disappear...
    comesfromArticle =false;
    }
    super.onExposed();
}
