How to send user define object to other activity

Question

I want to send user define object from one activity to another in android application.

I have created user class object and send this user object to my second activity from first activity.

Answer 1

Implement your class with Serializable interface. Then pass the object using

intent.putExtra("MyClass", obj);

and retrieve object by calling

getIntent().getSerializableExtra("MyClass");

1. Make sure your User class implements Parcelable.

   public class User implements Parcelable {
   
       ...........
       ............... 
   }
   

2. Send User object to SecondActivity as below:

   User userObject = new User();
   
   Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
   intent.putExtra("user_data", userObject);
   startActivity(intent);
   

3. Retrieving the User object in SecondActivity.

   User user = (User) getIntent().getParcelableExtra("user_data");
   

Here is good Tutorial about using Parcelable.
