I'm trying to parce a list of Int.
I've tried this solution: How to parcel List<Int> with kotlin , but not worked
data class Pizza(
var ingredients: ArrayList<Int>,
val name: String,
val imageUrl: String
) : Parcelable {
constructor(parcel: Parcel) : this(
TODO("ingredients"),
parcel.readString(),
parcel.readString()) {
}
override fun writeToParcel(parcel: Parcel, flags: Int) {
parcel.writeString(name)
parcel.writeString(imageUrl)
}
override fun describeContents(): Int {
return 0
}
companion object CREATOR : Parcelable.Creator<Pizza> {
override fun createFromParcel(parcel: Parcel): Pizza {
return Pizza(parcel)
}
override fun newArray(size: Int): Array<Pizza?> {
return arrayOfNulls(size)
}
}
Why don't you just try @Parcelize
! Another cool feature of Kotlin.
Enable kotlin experimental in gradle
//Make sure you have adeed
apply plugin: ‘kotlin-android-extensions’
androidExtensions {
experimental = true
}
Then
@Parcelize
data class Pizza(
var ingredients: ArrayList<Int>,
val name: String,
val imageUrl: String
) : Parcelable
Thats it.
There are several ways to write/read a list to/from a parcel, here is a simple solution.
First, use writeList to write a list into a parcel
override fun writeToParcel(parcel: Parcel, flags: Int) {
parcel.writeList(ingredients)
parcel.writeString(name)
parcel.writeString(imageUrl)
}
Then, use readArrayList to read the list from the parcel.
constructor(parcel: Parcel) : this (
parcel.readArrayList(Int::class.java.classLoader) as ArrayList<Int>,
parcel.readString(),
parcel.readString()
)
Hope it helps.
