    private var recyclerView: RecyclerView? = null
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_gallery)
        val activity_gallery = layoutInflater.inflate(R.layout.activity_gallery, null)
        setContentView(activity_gallery)
        //val mAdapter=GalleryAdapter(this,images)
        recyclerView=activity_gallery.actv_gallery_recyclerView as RecyclerView
        var mLayoutManager = LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false)
        recyclerView!!.layoutManager = mLayoutManager
        //recyclerView.layoutManager=LinearLayoutManager(this)
        //recyclerView.adapter=mAdapter

          val oRequest = object : StringRequest(Request.Method.GET, url, Response.Listener {
            response ->
            pd.hide()

              try {
                  val locationArray = JSONArray(response)
                  images=ArrayList(locationArray.length())
                  for (i in 0 until locationArray.length()){
                      val loc = locationArray.get(i) as JSONObject


                      images.add(Album(
