【问题描述】：
我用 ConstraintLayout 设计了一个活动，它包含许多应该滚动的元素，我这样做了，但它不起作用！
首先我设置了根元素，可滚动，这也不起作用。 然后我设置了根元素 linearlayout 并再次不起作用！
问题出在哪里？

【问题讨论】：
-
"but it not work!"什么都没有显示？有东西显示但不滚动？一切都滚动到底部？还有什么？ -
@pskink 滚动行为不起作用，除了页面底部的元素外，所有内容都显示出来。
-
什么
"elements that is in the bottom of page"？什么没有显示？ -
@pskink 最后一个
editText元素。并查看我的代码更新。 -
您发现问题了吗？我有类似类型的视图组展示位置，并且滚动视图不起作用。
