I'm building a ViewHolder and Adapter for a Fragment and when I try to make an OnClick for the ViewHolder, none of the contexts I pass in work. There is no `activity` from `getActivity()` that I can use, and `p0!!.context` nor `itemView.context` work either. Where should I be getting my context from, and how do I reference it?

    private var mCrimeRecyclerView: RecyclerView? = null
    private var mAdapter: CrimeAdapter? = null

    override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    // fragment_crime_list.xml has a RecyclerView element = crime_recycler_view
    // inflate the fragment into the activity
        val view = inflater!!.inflate(R.layout.fragment_crime_list, container, false)

        // grab the recyclerView and give it a required layoutManager
        mCrimeRecyclerView = view.findViewById(R.id.crime_recycler_view)
        mCrimeRecyclerView!!.layoutManager = LinearLayoutManager(activity)
        updateUI()
        return view
    }

    private fun updateUI() {
        val crimeLab = CrimeLab.get(activity)
        val crimes = crimeLab.getCrimes()
        mAdapter = CrimeAdapter(crimes)
        // Connect the adapter to the recyclerView
        mCrimeRecyclerView!!.adapter = mAdapter
    }

}
