Try this code

 intent.putCharSequenceArrayListExtra("ArrayListName", ArrayList)
Intent purchaseDetails= new Intent(getApplicationContext(), this.class);
purchaseDetails.putCharSequenceArrayListExtra("items", ArrayList);
startActivityForResult(purchaseDetails,0);

For First activity use below.

List<String> itemList = new ArrayList();
for(int i=0;i<5;i++){
itemList.add("i'th List"+i);
}

Intent intent= new Intent(this,ReportsActivity.class);
intent.putStringArrayListExtra("items", (ArrayList<String>) itemList);
startActivity(intent);

And get this array to another activity using 

Bundle bundle = getIntent().getExtras();
    List<String> itemList= bundle.getStringArrayList("items");

    for(int i=0;i<itemList.size();i++){
       Log.i("TAG", itemList.get(i));       
    }

If you want to do this in-memory, three solutions come to my mind:

  1. Make your data parcelable as described, e.g., by @takecare. See also http://developer.android.com/reference/android/os/Parcelable.html
  2. Use JSON to serialize your data. See, e.g., http://developer.android.com/reference/org/json/JSONTokener.html
  3. Use a singleton class as a holder for your data. You can also use the application object. See, e.g., Singletons vs. Application Context in Android?

You need to have look at this

http://developer.android.com/reference/android/os/Parcelable.html

Make your Model Parcelable. An example is given in the link.

Make your custom item parcelable and then put the array as a Parcelable array in a Bundle, to pass it to the activity.
