How to pass an Arraylist of Events through an Intent

Question

I'm trying to pass a list of events from one Activity to another one using intent, this is how I tried to do it:

on Activity 1:

ArrayList<Event>  eventsSelected= new ArrayList();
eventsSelected.add(new Event(Color.RED, dateClicked.getTime(), "event1"));
eventsSelected.add(new Event(Color.RED, dateClicked.getTime(), "event2"));
eventsSelected.add(new Event(Color.RED, dateClicked.getTime(), "event3"));
Intent i = new Intent(FirstActivity.this, SecondActivity.class);
i.putExtra("eventsSelected", eventsSelected);
startActivity(i);

but I didn't find how to get it on the second activity, I tried it this way but it didn't work :

on Activity 2:

Intent intent = getIntent();
ArrayList<Event> selectedDates = intent.getStringArrayListExtra("eventsSelected");

I didn't clearly understand how to do that! see i'm new on android, may you please explain more @JohnJoe — , Jul 28 '17 at 01:51

try `Bundle data=getIntent().getExtras() ; ArrayList aaa= (ArrayList) data.get("eventsSelected");` — jigar savaliya, Jul 28 '17 at 09:15
You should put that on the answers section not comments. @jigarsavaliya — , Jul 28 '17 at 17:56

You need to implements Serializable to your object class

public class Event implements  Serializable {
}

Also

i.putExtra("eventsSelected",eventsSelected);

where should I place that? – Jul 28 '17 at 01:52
In your Event class – John Joe Jul 28 '17 at 01:53
I don't have an Event class – Jul 28 '17 at 01:54
just to be clear, I'm using a Calendar over there and that's what I'm using the Events for – Jul 28 '17 at 01:54

just to clarify it works this way

ArrayList<Event> eventsSelected = new ArrayList<Event>();
intent.putExtra("eventsSelected", eventsSelected);

and in the second class

ArrayList<Event> eventsSelected = (ArrayList<Event>) getIntent().getSerializableExtra("eventsSelected");
