in my custom object, i have 7 attributes, 5 of them are strings, and were auto genereated in the contructor fine, but the other two did not generate automatically. the last two are of class Place and ArrayList<int>:

class Spot() : Parcelable{
 private var uid: String? = null
 private var timeFrom: String? = null
 private var timeTo: String? = null
 private var rate: String? = null
 private var description: String? = null
 private var place: Place? = null
 private var days : ArrayList<Int>? = null

 constructor(parcel: Parcel) : this() 
 uid = parcel.readString()
 timeFrom = parcel.readString()
 timeTo = parcel.readString()
 rate = parcel.readString()
 description = parcel.readString()
 
...

How do i parcelize them?

There are several methods to do it. You need to add the code yourself for ArrayList and Place Object in the constructor and writeToParcel methods.

constructor

constructor(parcel: Parcel) : this() 
 uid = parcel.readString()
 timeFrom = parcel.readString()
 timeTo = parcel.readString()
 rate = parcel.readString()
 description = parcel.readString()

 // Add the below to line of code
 days = parcel.readArrayList(Int::class.java.classLoader) as ArrayList<Int>?
 place = parcel.readParcelable<Place>(Place::class.java.classLoader)
 

writeToParcel

override fun writeToParcel(parcel: Parcel, flags: Int) 
 parcel.writeString(uid)
 parcel.writeString(timeFrom)
 parcel.writeString(timeTo)
 parcel.writeString(rate)
 parcel.writeString(description)

 // Add the below to line of code
 parcel.writeList(days)
 parcel.writeParcelable(place, flags)

 

And if I'm not wrong, Googles Place class is already Parcelable so this code should work.

Hope it helps!
