AndroidX 导致 AppCompatActivity 崩溃

Question

应用程序运行得很好，直到突然这个错误以某种方式触发：

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，它提供了一个组切换按钮并且即将对其进行测试

问：这个错误是什么意思，如何解决？？

更新

整个堆栈跟踪

Answer 1

您似乎误读了班级名称。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上提到的示例用法，如下所示

<com.nex3z.togglebuttongroup.button.CircularToggle
        android:id="@+id/choice_a"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="A"/>
