android.view.InflateException：二进制XML文件第6行：二进制XML文件第6行：膨胀类错误

Question

App made by someone else which I am testing, and learning from crashes and on logcat such error appears. Could you tell me what does it mean, and what am I supposed to do? I think there is something with package name. But when I checked package name of SquareImageView it showed my package: com.stek.ca_ltd.memestackupdating but not that displayed in logcat as a package name for this class(tabian.com.instagramclone2)

Answer 1

Android Runtime couldn't find tabian.com.instagramclone2.Utils.SquareImageView in your view. You are pointing to wrong class. Provide a proper package name for SquareImageView.

You, probably, customized SquareImageView into your own class. And, later forgot to change it in xml to your own customized SquareImageView.

Where is SquareImageView ?

Answer 2

这意味着您在XML文件中使用的类在您的项目中不存在，这就是为什么在放大类中的布局时会引发错误，您需要向其提供该类

Answer 3

Go to your layout_view_post.xml and there remake the SquareImageView widget. Most likely the error is because your project name is different ie not the same as tabian.com.instagramclone2 and you have copied and pasted the code from github. So before "Utils.SquareImageView" replace "tabian.com.instagramclone2" with your own package/project name or else the remake the widget.
