Android java.lang.RuntimeException:Parcelable在编写可序列化对象时遇到IOException（name=com.xxx.xxx.xxx.model.CategoryModel）

我正在将一个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

findNavControllerthis.navigateR.id.action_categoryFragment_to_serviceListFragment，参数

在片段B中：

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

您需要像下面的示例一样对数据类进行打包

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

ServiceModel是否可序列化？请提供完整的堆栈跟踪。@MikeM。请检查跟踪和ServiceModel模型是否可序列化这是我的服务模型：@SerializedNameid val id:Int，@SerializedNameVal serviceName:String，变量isSelected:Boolean，变量isCustomized:Boolean=false，变量TimeTake:String，变量price:String=0，@SerializedNamemin_price val minPrice:String，@SerializedNamemax_price val maxPrice:String，var serviceNameValueList:MutableList=arrayListOf，var serviceNameAndValueRecyclerAdapter:serviceNameAndValueRecyclerAdapter？：Serializable它正在尝试序列化ProviderDetailsActivity。我不太清楚Kotlin是如何处理序列化的，但看起来您有两个实现Serializable的RecyclerView.Adapters，这些适配器可能有一个活动的字段，您无法序列化该活动。我不知道为什么这些适配器实现Serializable，但您不应该尝试序列化它们；只是数据。

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