并且它的超类没有带有 Kotlin 和 DI 的 @Subscribe 注释的公共方法

Question

我已经检查了堆栈上的所有答案。但没有任何帮助。可能是 Kotlin + DI 的问题

所以我得到了一个例外，即 Eventbus 出于某种原因无法在演示者类中初始化自身。通过调试器，我看到从 onCreate 以正确方式执行的初始化方法。我使用与在其他类（Java 类）中使用的代码相同的代码，并且其他代码可以正常工作。请您给个建议，可能是哪里的问题

错误

    fun unsubscribe(){

Answer 1

MyProfileActivity 及其超类没有带有 @Subscribe 注释的 public 方法

强调我的。在此处从您的函数中删除 private：

@Subscribe
private fun updateActionsCount(event: VisitsEvent)
