约束布局内Scrollview内的Android约束布局(Android Constraint Layout inside Scrollview inside Constraint Layout)

我是我的搜索最接近的问题是： Scrollview内部约束布局不会滚动到父约束的底部

但是没有解决方案 = |。

我想做什么：

我有一个约束布局与3“部分”： 顶部栏 ， 中间内容和底部按钮 。

我想只为中间内容添加一个scrollview。因此，如果向下和向上滚动，则连续看到顶部栏和底部按钮

但是这个滚动视图不起作用，我认为是与scrollview中的“match_parent”相关的东西，但是我不能放这个选项，因为当scrollview在Constraint Layout中时 ，大小应该是相对的，如果我把匹配父类它不要填写所有空格。

我已经在使用：fillViewport =“true”，layout_constraintBottom_toBottomOf =“parent”

按照代码滚动视图名称：“scrollview2”

I'm my search the closest question was that: Scrollview inside constraint layout does not scroll to the bottom of the parent constraint

But there is no solution =|.

What I'm trying to do:

I have a constraint layout with 3 "parts": top bar, middle content and bottom button.

I want to put a scrollview only for the middle content. So if you scroll down and up you continuous to see the top bar and the bottom button

But this scroll view is not working, I think is something related with "match_parent" in the scrollview, but I can't put this option because as the scrollview is inside a Constraint Layout the size should be relative and if I put match parent it don't fill all spaces.

I'm using already: fillViewport="true", layout_constraintBottom_toBottomOf="parent"

Follow the code, scroll view name: "scrollview2"

最满意答案

好吧，我刚刚和朋友找到解决方案，首先我考虑删除这个，但由于其他人可能有同样的问题，这里的解决方案是：

我只是删除所有指南并重新构建，连接元素而不使用这么多指南。

有点幸运，因为我在改变方向时这样做了。

Well, I just found the solution with a friend, first I think about delete this, but since other people maybe have the same problem here is the solution:

I just remove all guidelines and build again, connecting the elements without using so many guidelines.

Was a little bit of lucky, because I did this to fix when change the orientation.
