我将模型列表从一个片段 A 传递到另一个片段 B，当我按下片段 B 上的最近应用程序按钮时，它崩溃了。

data class CategoryModel(

@SerializedName("id")
val id : Int,

@SerializedName("name")
val categoryName : String,

var isSelected : Boolean,

@SerializedName("image")
val imageUrl : String,

var isOpened: Boolean = false,

@SerializedName("service")
val services : MutableList<ServiceModel>,

var selectedServiceListAdapter: SelectedSeerviceListRecyclerAdapter? = null) : Serializable

这是片段 A ：

清单是

val localCategoryList: MutableList<CategoryModel> = arrayListOf()

我正在通过以下列表：

val argument = bundleOf("list" to localCategoryList)

findNavController(this).navigate(R.id.action_categoryFragment_to_serviceListFragment, argument)

在片段 B 中：

categoryList = arguments?.get("list") as MutableList<CategoryModel>

下面是堆栈跟踪

您需要像下面的示例一样打包数据类

Parcelize
data class WebViewTemplateParam(
    var type:FeedsType?,
    var placeholder: String = "",
    var message: String = "",
    var title: String? = "",
    var image: Int?= null):Parcelable
