Pass ArrayList from Activity to ListFragment?

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.

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);

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");
