【问题描述】：

我在尝试传递自定义对象时收到Parcelable encountered IOException writing serializable object 异常。下面是我的代码sn-p：

val intent = Intent(this@MyDowoodleActivity, CreateDowoodleActivity::class.java)
intent.putExtra("DATA", Activity())
startActivity(intent)

模型类：

 data class Activity(
    @SerializedName("isDeleted")
    val isDeleted: Int = 0,
    @SerializedName("startDate")
    **val startDate: Any = Any()** // I think this exception is because of Any type

 ):Serializable

但我想将Any() 作为类型。如何做到这一点？

【参考方案1】：

是的，你是对的。

Any() 对象未标记为可序列化，如果您将 startdate 转换为 Date 或 DateTime 甚至 long 并添加将 long 转换为 startdate 的方法，您应该没问题。
