How to send hashmap value to another activity using an intent

Question

How to send HashMap value from one Intent to second Intent?

Also, how to retrieve that HashMap value in the second Activity?

Answer 1

I hope this must work too.

in the sending activity

Intent intent = new Intent(Banks.this, Cards.class);
intent.putExtra("selectedBanksAndAllCards", (Serializable) selectedBanksAndAllCards);
startActivityForResult(intent, 50000);

in the receiving activity

Intent intent = getIntent();
HashMap> hashMap = (HashMap>) intent.getSerializableExtra("selectedBanksAndAllCards");

when I am sending a HashMap like following,

Map> selectedBanksAndAllCards = new HashMap<>();

Hope it would help for someone.
