Android kotlin: putParcelableArrayList(ArrayList<int>)和getParcelableArrayList<Int>()不能工作

companion object {
    fun newInstance(categoryId: Int, brandsList: ArrayList<Int>): Fragment {
        val fragment = CategoryAllAdsFragment()
        fragment.arguments = Bundle()
        fragment.arguments!!.putInt(Constant.CATEGORY_ID, categoryId)
        fragment.arguments!!.putParcelableArrayList(Constant.BRANDS_LIST, brandsList)
        return fragment
}

try {
    val brandsList = arguments!!.getParcelableArrayList<Int>(Constant.BRANDS_LIST)
} catch (ex: Exception) {
    throw Exception("brand list cannot be null")
}

putIntegerArrayList(Constant.BRANDS_LIST, array)

extras.getIntegerArrayList(Constant.BRANDS_LIST)

class BaseParcelable : Parcelable {
    var value: Any
    constructor(value: Any) {
        this.value = value
    constructor(parcel: Parcel) {
        this.value = Any()
    override fun writeToParcel(dest: Parcel?, flags: Int) {}
    override fun describeContents(): Int = 0
    companion object CREATOR : Parcelable.Creator<BaseParcelable> {
        override fun createFromParcel(parcel: Parcel): BaseParcelable {
            return BaseParcelable(parcel)
        override fun newArray(size: Int): Array<BaseParcelable?> {
            return arrayOfNulls(size)
}

companion object {
    fun newInstance(categoryId: Int, brandsList: ArrayList<Int>): Fragment {
       val fragment = CategoryAllAdsFragment()
       fragment.arguments = Bundle()
