How to Pass custom object via intent in kotlin

Question

fun launchNextScreen(context: Context, people: People): Intent {     val intent = Intent(context, NextScreenActivity::class.java)     intent.putExtra(EXTRA_PEOPLE, (Parcelable) people)     //intent.putExtra(EXTRA_PEOPLE, people as Parcelable)     //intent.putExtra(EXTRA_PEOPLE, people)     // tried above all three ways     return intent } 

I tried the above code to pass an instance of the People class via intent using kotlin, but I am getting an error. What am I doing wrong?

Answer 1

First, make sure the People class implements the Serializable interface:

class People : Serializable {     // your stuff } 

Inner fields of People class must also implement the Serializable interface, otherwise you'll get runtime error.

Then it should work:

fun launchNextScreen(context: Context, people: People): Intent {     val intent = Intent(context, NextScreenActivity::class.java)     intent.putExtra(EXTRA_PEOPLE, people)     return intent } 

To receive people back from Intent you'll need to call:

val people = intent.getSerializableExtra(EXTRA_PEOPLE) as? People
