How to pass Array of Object in Kotlin usin Intents

Question

I want to get the field "name" from "facilities" using intents and then replace in textview / Recyclerview. How do I do that?

Here are my adapters, response APIs, and activities.

This is an API response:

{
    "data": {
        "id": 7,
        "attributes": {
            "name": "Ancol",

            intent.putExtra("place", holder.place.text)
            intent.putExtra("rate", holder.rate.text)
            intent.putExtra("price", price)
            intent.putExtra("description", allList?.get(position)?.attributes?.description)

Activity :

class DetailActivity : AppCompatActivity() {

    lateinit var img_thumb : ImageView

    lateinit var tv_name : TextView
    lateinit var tv_tag : TextView
    lateinit var tv_price : TextView
    lateinit var tv_description : TextView
    lateinit var tv_timedays : TextView
    lateinit var tv_facilites: TextView

    var name : String = ""
    var place : String = ""
    var tag : String = ""
    var price : Int = 0
    var description : String = ""
    var time : String = ""
    var days : String = ""

    // variabel facility
    var facilities : String = ""

    @SuppressLint("SetTextI18n")
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_detail)

        tv_name = findViewById(R.id.tv_name)
        tv_tag = findViewById(R.id.tv_tag)
        tv_price = findViewById(R.id.tv_price)
        tv_description = findViewById(R.id.tv_description)
        tv_timedays = findViewById(R.id.tv_timedays)

        img_thumb = findViewById(R.id.img_thumb)

        name = intent.getStringExtra("name").toString()
        place = intent.getStringExtra("place").toString()
        tag = intent.getStringExtra("tag").toString()
        price = intent.getIntExtra("price",0)
        description = intent.getStringExtra("description").toString()
        time = intent.getStringExtra("time").toString()
        days = intent.getStringExtra("days").toString()

        // ambil data facility
        facilities = intent.getStringExtra("facility").toString()

        tv_name.text = "$name-($place)"
        tv_tag.text = tag
        val localID = Locale("in","ID")
        val numberFormat = NumberFormat.getCurrencyInstance(localID)
        tv_price.text = numberFormat.format(price)
        tv_description.text = description
        tv_timedays.text = "Time : $time || Days : $days"


        // set Text view untuk facility
        tv_facilites.text = facilities

    }
}

So Is there any way to do this in other way? I've never done this before. Please help. Thanks

also, you have to create more model class like below

Facilities.kt

data class Facilities(
val data: List<FacilitiesData>)

FacilitiesData.kt

data class FacilitiesData(
val attributes: AttributesData,
val id: Int)

AttributesData.kt

data class AttributesData(
val createdAt: String,
val name: String,
val publishedAt: String,
val updatedAt: String)

in your adapter in onBindViewHolder get your facilities list like below:

    val strFacilites = ArrayList<String>()

    for (i in facilities[position].data.indices){
       strFacilites.add(facilities[position].data[i].attributes.name)
    }

That's it, do Whatever you want with the strFacilites list.

                        }

                        public void setPublishedAt(String publishedAt) {
                            this.publishedAt = publishedAt;
                        }

                        public String getName() {
                            return name;
                        }

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

                    }

                }

            }

        }

    }
}

In Adapter you can pass dataModel object and send it in intent like this :

holder.cardview.setOnClickListener {
            val intent = Intent(it.context, DetailActivity::class.java)
            intent.putExtra("data_model", dataModel)
            it.context.startActivity(intent)
        }

In DetailActivity :

Intent intent = getIntent();
DataModel dataModel = (DataModel) intent.getSerializableExtra("data_model");
