    override fun onItemClicked(itemView: View, data: Model, itemIndex: Int) {
        // add logic here
    }
}

Then setup reusable-adapter

// setup adapter
ReusableAdapter<Model>(this)
    .adapterCallback(adapterCallback)
    .setLayout(R.layout.example_layout)
    .addData(listData)
    .isVerticalView()
    .build(recyclerview)

Component of reusable-adapter

// #1 create reusable-adapter
ReusableAdapter<Model>(context: Context)

// #2 adapter callback (required)
adapterCallback(adapterCallback: AdapterCallback<Model>) 

// #3 set layout of recyclerview (required)
setLayout(layout: Int)

// #4 set orientation view (required) [choose one]
isVerticalView()
isHorizontalView()

// #5 add list of data (required)
addData(listData: List<Model>)

// #6 update data for realtime change (optional)

Sample code

#1 Create xml item (item_negara.xml)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="16dp"
    android:orientation="vertical">

    <TextView
        android:id="@+id/tv_nama_negara"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Nama negara"
        android:textColor="@android:color/black"
        android:textSize="18sp" />

    <TextView
        android:id="@+id/tv_ibukota"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Ibukota"
        android:textSize="16sp" />

</LinearLayout>

#2 Create xml view on activity_main.xml

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/rv_negara"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:listitem="@layout/item_negara" />

#3 Create data class

data class Negara (
    val nama_negara: String,
    val ibukota: String
)

#4 Create list

val listNegara = listOf(
    Negara("Indonesia", "jakarta"),
    Negara("Malaysia", "Kuala Lumpur"),
    Negara("Thailand", "Bangkok"),
    Negara("Vietnam", "Hanoi"),
    Negara("Filipina", "Manila")
)

#5 Setup adapter callback

// create adapter callback for init component
val adapterCallback = object : AdapterCallback<Negara> {
    override fun initComponent(itemView: View, data: Negara, itemIndex: Int) {
        itemView.tv_nama_negara.text = data.nama_negara
        itemView.tv_ibukota.text = data.ibukota
    }

    override fun onItemClicked(itemView: View, data: Negara, itemIndex: Int) {
        Toast.makeText(this@MainActivity, data.nama_negara, Toast.LENGTH_SHORT).show()
    }
}

#6 setup reusable-adapter

// setup adapter
ReusableAdapter<Negara>(this)
    .adapterCallback(adapterCallback)
    .setLayout(R.layout.item_negara)
    .addData(listNegara)
    .isVerticalView()
    .build(rv_negara)
