将 Parcelable 对象传递给片段类型不匹配

Question

我是 kotlin 的新手，并试图将一个对象从我的适配器传递给一个片段。但是我在booklist. 它说Required: Parceleable Found: List<ResourcesList>?

我也试过使用putParcelableArrayListandputParcelableArray和Serializable但也有相同的类型不匹配。

我的数据模型如下所示：

@Parcelize
class ResourcesList (val id: Int,
                     val name: String,
                     val content: Contents,
                     val tags: List<Tags>) : Parcelable

@Parcelize
class Contents       (val id: Int,
                     val producers: List<Producers>,
                     val categories: List<Categories>,
                     val isAvailable: Boolean): Parcelable
@Parcelize
class Producers     (val name: String,
                     val role: String): Parcelable
@Parcelize
class Categories    (val id: Int,
                     val name: String): Parcelable

分段

class SeeAllFragment: Fragment() {

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        val view = inflater.inflate(R.layout.see_all_layout, container, false)


        val bookslist = arguments.getParceleable("bookslist")

        return view
    }

    companion object {

        fun newInstance(bookslist: List<ResourcesList>?): SeeAllFragment {

            val args = Bundle()
            args.putParcelable("bookslist", bookslist)
            val fragment = SeeAllFragment()
            fragment.arguments = args
            return fragment
        }
    }
}

Answer 1

将列表放入包中：

args.putParcelableArrayList("bookslist", bookslist as ArrayList<out Parcelable>?)

获取列表：

val bookslist = arguments.getParcelableArrayList<ResourcesList>("bookslist")
