我得到当我设置它抛出的异常contentView的MainActivity下面的XML。它已经可以正常工作，但是在其他活动上实施了几个小时之后，我遇到了此错误。我无法重现此错误的原因。可能更改了最小SDK版本或实施了新库。
我正在使用以下库：
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'
implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3'
