如何修复 Kotlin 中的重载分辨率歧义(no lambda)

发布于08月05日

I am having Overload Resolution Ambiguity error in this line:

departureHourChoice!!.selectionModel.select(currentHourIndex)个

For Reference:

departureHourChoice是ChoiceBox<Int>，从java.scene.control开始
currentHourIndex is an Int
重载解决模糊性发生在.select()方法中；它是重载的，可以接受两种参数:(T obj)或(int index).
The .select() method allows for an item in a ChoiceBox to be selected, and you can determine which one can be selected by referencing to that item or to it's index. In this case, I want it to be selected by Index (int).
这是一张错误的照片

如何解决超负荷解决歧义？

推荐答案

It seems that you are hit by this bug as a workaround you can :

currentHourIndex号框:

lateinit var departureHourChoice: ChoiceBox<Int>
...
val currentHourIndex = 1
departureHourChoice.selectionModel.select(currentHourIndex as Int?)

或者将ChoiceBox的声明改为java.lang.Integer，而不是Kotlin的Int:

lateinit var departureHourChoice: ChoiceBox<java.lang.Integer>
...
val currentHourIndex = 1
departureHourChoice.selectionModel.select(currentHourIndex)
