How to start activity from adapter in kotlin android

I have created a simple Adapter. I am trying to start Activity from within the Adapter when user clicks on an item. I am not able to get the context in the onClick. I am performing onClick inside MyViewHolder class. Here is my adapter code:

class LeadListAdapter(context:Context, private val leadList: List<Lead>) : RecyclerView.Adapter<LeadListAdapter.MyViewHolder>() {
    var activity:Context = context
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
        val inflatedView = parent.inflate(R.layout.custom_lead_row, false)
        return MyViewHolder(inflatedView)
    }

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

    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        holder.bindLead(leadList[position])
    }

    class MyViewHolder(v: View) : RecyclerView.ViewHolder(v), View.OnClickListener {
        //2
        private var view: View = v
        private var lead: Lead? = null

        //3
        init {
            v.setOnClickListener(this)
            v.trackButton.setOnClickListener(this)
        }

        //4
        override fun onClick(v: View) {
            val intent = Intent(activity) //Getting error here
        }

        fun bindLead(lead: Lead) {
            this.lead = lead
            view.leadName.text = lead.cusName
            view.leadMobileNumber.text = lead.mobileNo.toString()
            view.loanAmount.text = lead.amount.toString()
            view.leadId.text = "Lead Id: ${lead.id.toString()}"
            view.loanType.text = lead.productType
            view.loanTypeIcon.text = getCharsFromWords(lead.productType)
        }

        private fun getCharsFromWords(productType: String?): String? {
            val words = productType!!.split(Regex("\\s+"))
            val quote: String
            val sb = StringBuilder()
            for (word in words) {
                sb.append(word[0].toString())
            }
            quote = sb.toString()
            return quote
        }

        companion object {
            //5
            private val LEAD_KEY = "LEAD"
        }
    }

}

You're getting an error at that line because Intents are not declared like that. You need to also supply a java Class as the second parameter.

Refer to the documentation for the correct ways of obtaining an Intent object.

EDIT

In regards to my comment, you need to state your ViewHolder class as a inner class. ie:

inner class MyViewHolder(holder: View) : RecyclerView.ViewHolder(holder){}

As stated in the Kotlin Reference Manual, unless modified as a inner class, nested classes will not have access to the outer class' members.

Unresolved reference context

NOTE

You should return Context object also.

return MyViewHolder(inflatedView,context)

Then

 class MyViewHolder(v: View,context:Context) :
