Use Intent to transfer Java objects between activities in Android projects -- Implement Parcelable InterfaceUsing Intent to implement Java object transfer between activities in Android projects, there are two ways: one is the passed object implements the Serializable interface; the other is the passed object implements the Parcelable interface, this blog summarizes how to implement Java object transfer when passing objects to implement the Parcelable interface:

, the default value is used.Copy the Code code as follows:
def f (a,b,c=10):
Return A+b+c
Print (f (3,2))Print (f (3,2,1))
At the first call to function f, we do not have enough values, C is not assigned, C will use the default value of 10.
The second time the function is called, C is assigned a value of 1, and the default value is no longer used.

Use of the parcelable interface in Android Development
For Android, the transmission of complex types is mainly to convert their classes into basic byte arrays, and data passing between activities is implemented through intent. Android serialization objects can be implemented in two ways: serializable interface or parcelable interface. The serializable interface is JavaSe itself is supported, while parcelable is a feature specific to Android, which is more efficient than serializable int
