Android studio: how to pass customed objects in intent

Question

So I encountered a problem about the Intent. A little background:

I have a customed class called Workout (Data structures) with constructor and all this stuff. The point is i want to make an intent which kinda looks like this:

Workout workoutP=new Workout(...);

...

intent.put????("workout", workoutP);

Is there any way to pass it from one activity to another?

Try this:-

Implement Serializable Interface into Workout class then follow following

steps

public class Workout implements Serializable


//To pass:
intent.putExtra("YourClass", obj);

// To retrieve object in second Activity
getIntent().getSerializableExtra("YourClass");

You forgot to mention that `Workout` must be serializable – Mạnh Quyết Nguyễn May 18 '18 at 09:32
so the title needs to be: public class Workout implements Serializable ? – Maayan Kaidar May 18 '18 at 09:58
yes make your class as you mentioned in the comment. – Mr. Roshan May 18 '18 at 10:03

Sending side

intent.putExtra("workout", workoutP);

Receiving side

Intent intent = getIntent();
    Workout objref = (Workout ) intent.getSerializableExtra("workout");
