Pass list of objects from one activity to other activity in android

Question

I want to pass a list of objects from one activity from another activity. I have one class SharedBooking Below:

public class SharedBooking {   public int account_id;   public Double betrag;   public Double betrag_effected;   public int taxType;   public int tax;   public String postingText; } 

Code from Calling activity:

public List<SharedBooking> SharedBookingList = new ArrayList<SharedBooking>();  public void goDivision(Context context, Double betrag, List<SharedBooking> bookingList) {   final Intent intent = new Intent(context, Division.class);       intent.putExtra(Constants.BETRAG, betrag);           intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);     context.startActivity(intent);         } 

COde on called activity:

Bundle extras = getIntent().getExtras(); if (extras != null) {   amount = extras.getDouble(Constants.BETRAG,0); } 

How can I send the list of SharedBooking from one activity and receive that on other activity?

Please suggest me any usable link or sample code.

Answer 1

First, make the class of the list implement Serializable.

public class MyObject implements Serializable{} 

Then you can just cast the list to (Serializable). Like so:

List<MyObject> list = new ArrayList<>(); myIntent.putExtra("LIST", (Serializable) list); 

And to retrieve the list you do:

Intent i = getIntent(); list = (List<MyObject>) i.getSerializableExtra("LIST"); 

That's it.
