blackberry - 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。避免这个空白的一些想法？

可能是黑莓操作系统对这个人的奇怪态度...... 当在两个文本框之间切换虚拟键盘时，黑莓中的奇怪行为

Answer 1

private VerticalFieldManager manBackground;
private NewsList newsList;

问题解决了，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();
}
