Using AbsSavedState instead of BaseSavedState in derived class to support inherited custom view

RegularPostView.kt

class RegularPostView : BasePostView {
    ...
    internal class SavedState : AbsSavedState {
        var dividerColorResId: Int = 0

        constructor(superState: Parcelable) : super(superState)

        constructor(source: Parcel, loader: ClassLoader?) : super(source, loader) {
            dividerColorResId = source.readInt()
        }

        override fun writeToParcel(out: Parcel, flags: Int) {
            super.writeToParcel(out, flags)
            out.writeInt(dividerColorResId)
        }
        ...
    }
}
