Android Studio – Trying to open another activity in recycles view using onclick

Trying to get a button to open another activity in android studio using kotlin. I am user a recycles view to do so. I have view card and want to edit the data in the card so I am user onClick to get the page to respond but that does seem to work I tried researching it but nothing come up that I can make sense of. Here is the code.

Thank you for all your help I appreciate it

This is the adapter class:

```class EventAdapter(var mListener: onItemClickListener, var context: Context, val items: ArrayList<EventModelk>):
        RecyclerView.Adapter<EventAdapter.ViewHolder>()  {



    interface onItemClickListener {
        fun onItemClick(position: Int)
    }

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {



            val itemview = LayoutInflater.from(context).inflate(
                R.layout.eventitems,
                parent,
                false,
            )
        return ViewHolder(itemview, mListener)

    }

    override fun onBindViewHolder(holder: ViewHolder, position: Int) {


        val item = items[position]

        holder.setEmail.text = item.eEmail
        holder.setNotes.text = item.nNotes
        holder.setData.text = item.dDate
        holder.setTime.text = item.tTime
        if (item.repeat == 1) {

            holder.setReap.isChecked = true
            // holder.setReap.text = item.repeat.toString()
        }

        if (position % 2 == 0) {
            holder.main.setBackgroundColor(
                ContextCompat.getColor(
                    context,
                    R.color.colorLightGray
                )
            )
        } else {
            holder.main.setBackgroundColor(ContextCompat.getColor(context, R.color.colorWhite))
        }
        holder.pushimg.setOnClickListener {

            if (context is UpdateDataInfo) {
                (context as UpdateDataInfo).updateEvent(item)
            }
        }
//       interface onItemClickListener{
//            fun onItemClick(position: Int)
    }

    override fun getItemCount(): Int {
    return items.size
    }

    class ViewHolder(view: View,onItemClickListener: onItemClickListener): RecyclerView.ViewHolder(view),onItemClickListener {

        val main: CardView = view.IIMain
        val setData: TextView = view.set_date
        val setTime: TextView = view.set_time
        val setEmail: TextView = view.Tv_email
        val setNotes: TextView = view.set_note
        val setReap: CheckBox =view.is_repeat
        val pushimg: ImageView = view.img_edit
        val onItemClickListener = onItemClickListener


        override fun onItemClick(position: Int) {
            onItemClickListener.onItemClick(absoluteAdapterPosition)
        }

    }
}```

This is my code for getting the click to go to another activity:

class CurrentSch : AppCompatActivity(), EventAdapter.onItemClickListener {

    //private var change =imageView2?.isClickable
    var STORAGE_LOCAL =true

    val eventlist = ArrayList<EventModelk>()

    @RequiresApi(Build.VERSION_CODES.N)
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.currentsch)


        btnNewApp2.setOnClickListener {
            val intent = Intent(this, NewPlan::class.java)
            startActivity(intent)
        }

        seeAllEventInPlan()
    }

    //private var change =imageView2?.isClickable

    private fun getEventist(): ArrayList<EventModelk>{
        val eventdatabase = EventDatabasek(this)

        return eventdatabase.veiwEvent()
    }

    fun seeAllEventInPlan() = if(getEventist().size >0){

        ryc_eventLists.visibility = View.VISIBLE
        viewnotview.visibility = View.GONE

        ryc_eventLists.layoutManager = LinearLayoutManager(this)
        val eventAdapter = EventAdapter(this,this, getEventist())
        ryc_eventLists.adapter = eventAdapter

    }else{
        ryc_eventLists.visibility = View.GONE
        viewnotview.visibility = View.VISIBLE
    }
    override fun onItemClick(position: Int) {

        val item = eventlist[position]
        img_edit.setOnClickListener {
            val intent = Intent(this, UpdateDataInfo::class.java)
            intent.putExtra("Events", position)
            startActivity(intent)
        }
    }
}

    Inside the onBindViewHolder function, simply call mListener.onItemClick(position) for example if you wanted to open another Activity on click of setData, then you can write below code in onBindViewHolder

    holder.setData.setOnClickListener { mListener.onItemClick(position) }

    according to your above code , you have made callbacks where you calling thee adapter you will get callback there and you will open a activity there .. .. but you can simple open your new activity from adapter like this ..

    holder.itemView.setOnClickListener(View.OnClickListener {

        val intent  = Intent (context,SomeActivity::class.java)
        context.startactivity(intent)
    })
