AndroidX 导致 AppCompatActivity 崩溃
AndroidX causing AppCompatActivity to crash
应用程序 运行 很好，直到突然以某种方式触发此错误：
E/AndroidRuntime: at androidx.appcompat.app.AppCompatDelegateImpl.setContentView(AppCompatDelegateImpl.java:543)
at androidx.appcompat.app.AppCompatActivity.setContentView(AppCompatActivity.java:136)
at com.thorsguild.company..Activities.MainActivity.onCreate(MainActivity.java:89)
我应该提一下，我刚刚开始使用 this library from GitHub，它提供一个组切换按钮并且正准备测试它
问：这个错误是什么意思，如何解决？？

您好像看错了 class 这个名字。您应该使用 CircularToggle 但您使用的是库中不存在的 CircularButton。您可以查看github中提到的示例用法，如下
<com.nex3z.togglebuttongroup.button.CircularToggle
android:id="@+id/choice_a"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="A"/>
