Question

尝试传递自定义对象时，我遇到Parcelable encountered IOException writing serializable object异常。以下是我的代码段：

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

但是我想将Any()作为类型。该怎么做？

日志显示以下内容：

是的，没错。

Any（）对象未标记为可序列化，如果您将startdate转换为Date或DateTime甚至是long，并添加了将longdate转换为startdate的方法，就可以了。

获取Parcelable遇到IOException编写可序列化对象
