I want to pass a list of objects from one activity from another activity. I have one class SharedBooking Below:

public class SharedBooking {         


        

Answer 1

If there is someone who is looking for answer this is how i implemented it using Kotlin.

Parcelable object class

data class CollectedMilk(
    @SerializedName("id")
    var id: Int,
    @SerializedName("igicuba")
    var igicuba: Int,
    @SerializedName("collector")
    var collector: String?,
    @SerializedName("collected")
    var collected: Int,
    @SerializedName("accepted")
    var accepted: Int,
    @SerializedName("standard")
    var standard: String?,
    @SerializedName("created_at")
    var created_at: String?,
    @SerializedName("updated_at")
    var updated_at: String?,
): Parcelable {

    constructor(parcel: Parcel) : this(
        parcel.readInt(),
        parcel.readInt(),
        parcel.readString(),
        parcel.readInt(),
        parcel.readInt(),
        parcel.readString(),
        parcel.readString(),
        parcel.readString()
    )

    override fun describeContents(): Int {
        return 0
    }

    override fun writeToParcel(parcel: Parcel?, int: Int) {
        parcel?.writeInt(id)
        parcel?.writeInt(igicuba)
        parcel?.writeString(collector)
        parcel?.writeInt(collected)
        parcel?.writeInt(accepted)
        parcel?.writeString(standard)
        parcel?.writeString(created_at)
        parcel?.writeString(updated_at)
    }

    companion object CREATOR : Parcelable.Creator {
        override fun createFromParcel(parcel: Parcel): CollectedMilk {
            return CollectedMilk(parcel)
        }

        override fun newArray(size: Int): Array {
            return arrayOfNulls(size)
        }
    }
}

Then in Fragment

collectedMilkAdapter.onItemClick = { collectedMilk ->
            Toast.makeText(
                MccApp.applicationContext(),
                "Collector: " + collectedMilk.collector,
                Toast.LENGTH_LONG
            ).show()

            val intent = Intent(MccApp.applicationContext(), CollectedMilkActivity::class.java)
            val bundle: Bundle = Bundle()

            bundle.putParcelableArrayList("collectedMilk", collectedMilkArrayList)
            intent.putExtras(bundle)

            activity?.startActivity(intent)
        }

Then on another Activity my Detail Activity

Global Variable

private lateinit var collectedMilk: ArrayList

In Function or OnCreate Activity

val bundle = intent.extras
        collectedMilk = (bundle?.getParcelableArrayList("collectedMilk") as ArrayList)

        Toast(this).showCustomToast(
            this,
            ""+collectedMilk,
            dark
        )
