如何在NestedScrollView中实现ConstraintLayout [英] How to implement ConstraintLayout in NestedScrollView

问题描述

如果TextView的文本比水平LinearLayout中包装的其他TextView少得多，则ConstraintLayout的行为将不一致.如果左TextView中的字符不小于右TextView中的字符，则说明该字符运行良好. 请在随附的屏幕截图中引用红色文本和绿色文本.

ConstraintLayout is behaving inconsistently if a TextView has very fewer texts than other TextView wrapped in horizontal LinearLayout. If a character in left TextView is not much less than right TextView then it is working great. Please refer red color texts and green color texts in attached screenshots.

下面是用于布局的XML:

Below is the XML for layout:

推荐答案

按照我与之交谈的Google开发人员的说法，constraintLayout版本1.0.2中有一些关于wrap_content的错误.他建议使用1.1.0-beta4版本，而通过使用1.1.0-beta4版本，我的问题已得到解决.

There are some bugs regarding wrap_content in constraintLayout version 1.0.2 as per google developer whom I talked. He suggested to use 1.1.0-beta4 version and by using version 1.1.0-beta4 my issue has been fixed.
