android - How to put a List in intent

Question

I have a List in one of my activities and need to pass it to the next activity.

private List<Item> selectedData;  

I tried putting this in intent by :

intent.putExtra("selectedData", selectedData);  

But it is not working. What can be done?

Like howettl mentioned in a comment, if you make the object you are keeping in your list serializeable then it become very easy. Then you can put it in a Bundle which you can then put in the intent. Here is an example:

class ExampleClass implements Serializable {
    public String toString() {
        return "I am a class";
    }
}

... */ Where you wanna create the activity /*

ExampleClass e = new ExampleClass();
ArrayList<ExampleClass> l = new ArrayList<>();
l.add(e);
Intent i = new Intent();
Bundle b = new Bundle();
b.putSerializeable(l);
i.putExtra("LIST", b);
startActivity(i);
