How to create onclick event in adapter using interface android?

Question

How can I create on click event using interface?

In my application I\'ve created view click interface to detect clicking on adapter items into parent activity. After

Answer 1

In Kotlin the proper way doing this, is using callbacks instead of Java Interfaces. Example:

class MyAdapter(private val callback: (YourModel) -> Unit) {

    override fun onBindViewHolder(holder: DataBoundViewHolder, position: Int) {
        bind(holder.binding, items!![position])
        holder.binding.executePendingBindings()
        holder.binding.root.setOnClickListener { callback(binding.model) }
   }
}

And create the adapter somewhere using

MyAdapter myAdapter = MyAdapter( { println{"Clicked $it"} })

Edit: Since the Asker would like to see a full working code i used the code from Sumit and replaced the Interfaces with Kotlin-Callbacks.

class ChapterAdapter(private val activity: Activity, 
     val mWords: ArrayList,
     val callback: (Any) -> Unit) : 
     RecyclerView.Adapter() {


        override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
            val layoutInflater = LayoutInflater.from(parent.context)
            return ViewHolder(layoutInflater.inflate(R.layout.layout_capter_raw, parent, false))
        }

        override fun onBindViewHolder(holder: ViewHolder?, position: Int) {
            val item = mWords[position]

            holder.layout_chapter_name.setOnClickListener( callback {$it})
        }

        override fun getItemCount(): Int = mWords.size

        override fun getItemId(position: Int): Long = super.getItemId(position)

        override fun getItemViewType(position: Int): Int = super.getItemViewType(position)


        class ViewHolder(view: View) : RecyclerView.ViewHolder(view) {
            val txt_capter_name = view.txt_capter_name
        }

and finally creating the Adapter

listAdapter = ChapterAdapter(activity, _arrChapterList, { 
  toast( "Clicked $it", Toast.LENGTH_LONG) 
})
