Pass ArrayList from Activity to ListFragment?

Question

I am trying to implement a fragment layout. I have an activity that servers as a SplashScreen & fetches some data from the web and creates an ArrayList of my custom objects.

Normally If I were using a ListView I would just do the following.

private ArrayList<Articles> articles;

private void isComplete() {
         Intent intent = new Intent(SplashScreen.this, ListActivity.class);
         intent.putExtra("data", articles);
         startActivity(intent);
         finish();
    }

How can I do pass the same data to a Fragment? Your help I much appreciated.

It depends on the type of arraylist

putIntegerArrayListExtra(String name, ArrayList value)
putParcelableArrayListExtra(String name, ArrayList value)
putStringArrayListExtra(String name, ArrayList value)
putCharSequenceArrayListExtra(String name, ArrayList value)

Then you can read from you next activity by replacing put with get with key string as argument,eg

myIntent.getStringArrayListExtra("arrayPeople");

use putExtra to pass value to an intent. use getSerializableExtra method to retrieve the data

If I have two activities A and B I want to pass ArrayList> value to Activity B then I will use the following code in class A

Pass ArrayList> data from Activity A to Activity B

Intent intent = new Intent(this, B.class);
HashMap<String, String> hm = new HashMap<String, String>();
hm.put("sunil", "sahoo");
ArrayList<HashMap<String, String>> arl = new ArrayList<HashMap<String, String>>();
arl.add(hm);
intent.putExtra("arraylist", arl);
startActivityForResult(intent, 500);

Retrieve the value in Activity B

In class B i will write the folowing code to retrieve the data

ArrayList<HashMap<String, String>> arl =(ArrayList<HashMap<String, String>>) getIntent().getSerializableExtra("arraylist");
System.out.println("...serialized data.."+arl);

Question is about ListFragment. Not about Activity.
