搜索一下,无法专门找到这个问题。专门创建了一个帐户来询问这里发生了什么?!
第一次使用ConstraintLayout - 我取得了很好的成功,但由于某种原因,我不能让我的两个组件发挥得很好。
这就是我希望它看起来像(通过破坏约束和硬编码来完成):
......如果我试图约束" LabelJournal"这就是我弄得一团糟的混乱。和" linearLayout2":
名为" LabelJournal"的组件正在出现问题。和" linearLayout2"。这就是我的LayoutFile的样子......它是一个WIP,所以我现在知道那里有很多文本值的硬编码等等 - 我只想弄清楚什么在世界正在导致这两个组件卡在父母的顶端:

也许我也应该提一下 - 我的约束布局中没有出现任何错误(尽管有大量关于硬编码文本的警告以及我以后会处理的内容)。
答案 0 :(得分:0)
好吧花了我一个小时的修修补补 - 但是我的布局HTML中包含&#34; layout_constraintBottom_toTopOf&#34;引起了这个问题。我不知道它是订购的东西还是一些奇怪的绘图层次结构。这对我来说没有任何意义。
