How to send an object from one Android Activity to another using Intents?

Question

How can I pass an object of a custom type from one Activity to another using the putExtra() method of the class Intent?

Answer 1

implement serializable in your class

public class Place implements Serializable{
        private int id;
        private String name;

        public void setId(int id) {
           this.id = id;
        }
        public int getId() {
           return id;
        }
        public String getName() {
           return name;
        }

        public void setName(String name) {
           this.name = name;
        }
}

Then you can pass this object in intent

     Intent intent = new Intent(this, SecondAct.class);
     intent.putExtra("PLACE", Place);
     startActivity(intent);

int the second activity you can get data like this

     Place place= (Place) getIntent().getSerializableExtra("PLACE");

But when the data become large,this method will be slow.
