我没有从Kotlin编译器的问题中找到解决方案。
我的Kotlin版本（来自gradle） - private val transitionListener = object : Transition.TransitionListener {
override fun onTransitionEnd(transition: Transition) {
showContentAfterTransition()
}
override fun onTransitionResume(transition: Transition) {
}
override fun onTransitionPause(transition: Transition) {
}
override fun onTransitionCancel(transition: Transition) {
showContentAfterTransition()
}
override fun onTransitionStart(transition: Transition) {
}
}
这是我的代码（代码的一部分）：

这是Kotlin编译器的错误：

答案 0 :(得分：6)
指定变量的确切类型或删除private修饰符。
private val transitionListener: Transition.TransitionListener = object : Transition.TransitionListener {
override fun onTransitionEnd(transition: Transition) {
showContentAfterTransition()
}
override fun onTransitionResume(transition: Transition) {
}
override fun onTransitionPause(transition: Transition) {
}
override fun onTransitionCancel(transition: Transition) {
showContentAfterTransition()
}
override fun onTransitionStart(transition: Transition) {
}
}
似乎kotlin中有一个奇怪的错误，在这种情况下类型推断不起作用。
