Is it possible to to put an object of type Object into an intent as a Extra? I have a variable of type object and won't know until it is assigned a value as to what the object datatype is. Maybe something to do with serialization or as a bundle i'm not sure? And then in the next activity how do I then get this value in order to store it in an ArrayList<Object> ?
回答1:
Bundle by way of Intent#putExtra does not have any function to add an Object. You can only pass in a Parcelable or a Serializable object. Any object you want to pass via an Intent must implement one of those interfaces. It's recommended to implement Parcelable there is a brief guide here: Pass by value Parameters using Parcelables.
