How do you pass a List to a bundle if Placeholder is already an interface

Question

According to this the recommended solution is to have Placeholder implement the Parcelable interface. However in my case Placeholder is already an interface and thus cannot implement the Parcelable interface.

Interfaces don't implement other interfaces, they extend them. — Michael, Mar 18 '20 at 17:45
Do you have properties for your interface Why don't you pass implementation of Interface — Manoj Mohanty, Mar 18 '20 at 19:17

Differently than classes, whereas you cannot have one class extending from two or more classes, interfaces can extend multiple interfaces.

The syntax is very easy:

public interface A {
}

public interface B {
}

public interface C extends A, B {
}

Also bear in mind that a class can implement multiple interfaces.
