Passing List

Question

I have a List in one of my activity. I need to pass it to another activity and use the elements in it.

ActivityOne.java

newsListy.add(new News(title, description, thumbnail);
      Intent newsIntent = new Intent(getActivity(),Second.class);
                    newsIntent.putExtra("NewsItems", newsListy);
startActivity(newsIntent);

Second.class

data =  in.getSerializableExtra("NewsItems");

Also, retrive value from the list and assign it to a String title, description and thumbnail

If you want to pass a custom object between activities, like for instance a List of a custom object :

List<'CustomObject'>

Your custom object class have to implement Parcelable.

Be sure that your Object implements Serializable interface or else you will get some kind of parse exception. But as @Alex mentioned also declare your List's generic type with your Object like : List<'CustomObject'>

Implementing Parcelable is the best way to do it, but it requires more effort.
