我有一个用于recyclerview的自定义适配器
BaseRecyclerView.kt
abstract class BaseRecyclerView {
abstract class Adapter<ITEM : Any, B : ViewDataBinding>(
private val listener : ((s : Station) -> View.OnClickListener)?,
@LayoutRes private val layoutResId: Int,
private val bindingVariableId: Int? = null
): RecyclerView.Adapter<ViewHolder<B>>()
...
它接受可为null的函数作为参数， 所以我在活动中为recyclerview创建了一个对象
StationActivity.kt
deprListView.adapter = object : BaseRecyclerView.Adapter<Station, StationListItemBinding>(
listener = { s ->
View.OnClickListener {
Toast.makeText(this@StationActivity, "${s.stationName} : ${s.stationCode}", Toast.LENGTH_SHORT).show()
}
},
layoutResId = R.layout.station_list_item,
bindingVariableId = BR.station
) {}
它在编辑器中没有显示任何错误，但是在构建时会返回错误
java.lang.IllegalStateException: Backend Internal error: Exception during code generation
设置listener = null,时没有错误（我检查侦听器是否为null，然后将侦听器设置为非null）
所以对于kotlin中的函数肯定存在一些误解... 什么可能导致此错误？
