如何在从片段调用的BottomSheet中使用setOnEditorActionListener？

如何解决如何在从片段调用的BottomSheet中使用setOnEditorActionListener？

我目前正在使用带有Kotlin的android-studio开发应用程序。

当从setonEditorActionListener调用的BottomSheet中的Fragment触发时，我想使用我的函数。

但是在我的代码中setonEditorActionListener不会触发。

*我想在CountSettingFragment.kt下面添加评论的地方使用我的函数：

如何解决此问题？

Android Studio：3.3.2

解决方法

我无法检查功能的原因是，当我将print方法更改为println方法时，可以使用该功能了。
