推荐答案

您将无法在其中实际放置EditField.最好的选择是只使用VerticalFieldManager并在其中堆叠LabelFields/EditFields.它仍然会滚动，只是不会是ListField.

You won't be able to actually place the EditField in there. Your best bet is to use just a VerticalFieldManager and stack LabelFields/EditFields in there. It will still scroll, just won't be ListField.
