What should I pay attention to when uploading objects to an activity in android?

I implemented the Parcelable interface through serializable, because it was relatively lazy and I didn't want to implement the Parcelable interface.

1. Modify the Class. Because Serializable is passed, inherit implements Serializable after the class.

2. Pass the value

Intent. putExtra (sid, scart );

You can use putExtra directly.

3. Receive Value

Scart = (GoodsList_Details) intent. getSerializableExtra (sid );

In this way, we can basically solve the needs of more than 80% of our friends.

The above method is indeed feasible, but the class extension adds a field, so this transfer is not easy.

Error:

Java. lang. RuntimeException: Parcelable encountered IOException writing serializable object

Check all the classes on the Internet, including the referenced classes. serializable serialization is required.

View my code

Private List Items;

GoodsSpec has no serializable, so I don't hesitate to add this. Okay, everything is OK. record it.
