AAPT：错误：'techport'与属性layout_constraintStart_toEndOf (attr) 引用|枚举 [parent=0] 不兼容

Question

大家好，我是编程新手。我在做布局，当启动模拟器时，我得到了这个错误

D:SkyScannerappsrcmainreslayoutfragment_main.xml:122: AAPT: error: 'techport' is incompatible with attribute layout_constraintStart_toEndOf (attr) reference|enum [parent=0].

我在媒体上读到你需要删除'kotlin-parcelize'
，但它仍然对我不起作用，有人能帮我吗？我在我应该放的媒体上看到了我，我该怎么办？

`'kotlin-parcelize'`      but it doesn't helped me

我已经从我的建筑Graddle中移除了kotlin扩建部分这是我的代码

Answer 1

刚刚遇到了一个与您类似的错误，通过不将NestedScrollView约束为include来解决它。

Answer 2

浏览所有约束Layouts，并检查声明的Attributes是否正确。我的一个TextViews具有"；layout_contraintEnd_toEndOf；=0。我在家长身上设置了它，它又起作用了！
