我正在开发一个OS 5.0中的应用程序，其中包含一个显示结果的表格，为此我使用了一个非常流行的代码，它实现了一个Listfield和一个TableRowManager。每一行都比屏幕宽度宽，所有数据都显示出来，它通常运行良好......除了一个非常烦人的傻笑。
如果我向右滚动，可以通过滑动手势或使用导航按钮，屏幕按预期滚动，但向下滚动到下一行，焦点返回到该行的最左侧。我需要做的是保留listfield中的位置。在调用屏幕中（添加了此Listfield），Listfield将添加到VerticalFieldManager中。然后将其添加到HorizontalFieldManager。
我的HorizontalFieldManager启用了HORIZONTAL_SCROLL，而包含Listfield的VerticalFieldManager却没有。添加它没有任何效果。每个管理器使用参数NO_SCROLL_RESET但滚动确实被重置。
我有点像BB编码的新手，但我很确定我需要覆盖某种方法，但哪一个让我望而却步。我在这里和其他论坛上一遍又一遍地搜索，但无济于事。我希望有人遇到同样的问题，并有解决方案。
以下是代码示例（不是很小，我很害怕）
