Filter in adapter

How can I do it? What I want is for me to show only the items that within the holder.textEstado.text = filtro.estadoPartido contain the string "Pending" and this is what I do:

class AdapNJ(internal var context: Context, internal var listJornadas: List<ModelJor>) : RecyclerView.Adapter<AdapNJ.ViewHolder>() {

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

    @RequiresApi(Build.VERSION_CODES.O)
    @SuppressLint("SetTextI18n")
    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        val jornada = listJornadas[position]

        val array: ArrayList<ModelJor> = ArrayList()

        val filtro: ModelJor? = array.find{ it.estadoPartido == "Pendiente"}

        val fecha = jornada.fecha

        if (fecha == ""){
            holder.textFecha.text = ""

        }else{

            val fecha = filtro!!.fecha + Directions.ANYO1
            val parser = SimpleDateFormat("dd/MM/yyyy")
            val date = parser.parse(fecha) as Date
            val espanol = Locale("es", "ES")
            val formatter = SimpleDateFormat("EEEE dd 'de' MMMM 'del 'yyyy \n'  a las '", espanol)
            holder.textFecha.text = (formatter.format(date)) + filtro.hora
        }


        holder.textEquipoLocal.text = filtro!!.nomLocal
        holder.textResulLocal.text = filtro.resulLocal
        holder.textEstado.text = filtro.estadoPartido
        holder.textResulVisi.text = filtro.resulVisitante
        holder.textEquipovisi.text = filtro.nomVisitante


        if(filtro.resulLocal!! < filtro.resulVisitante.toString()) {
            holder.textResulLocal.setTextColor(Color.RED)
            holder.textResulVisi.setTextColor(Color.GREEN)

        }else if(filtro.resulLocal!! > filtro.resulVisitante.toString()) {
            holder.textResulLocal.setTextColor(Color.GREEN)
            holder.textResulVisi.setTextColor(Color.RED)
        }

        Picasso.get()
                .load("http://ffcv.es/ncompeticiones/" + filtro.escudoLocal)
                .placeholder(R.mipmap.ic_launcher_round)
                .resize(50, 50)
                .centerCrop()
                .into(holder.imageEscLocal)

        Picasso.get()

                .centerCrop()
                .into(holder.imageEscVisi)
    }

    override fun getItemCount(): Int = listJornadas.size

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

        var textFecha: TextView = itemView!!.findViewById(R.id.tv_Fecha)as TextView
        var textEstado: TextView = itemView!!.findViewById(R.id.tv_Estado) as TextView

        var imageEscVisi: CircleImageView = itemView!!.findViewById(R.id.tv_esc_visi) as CircleImageView
    }
}

The error: kotlin.KotlinNullPointerException at com.ramon.rafelcf.Jornadas.SinJugar.AdapNJ.onBindViewHolder (AdapNJ.kt: 48) com.ramon.rafelcf.Jornadas.SinJugar.AdapNJ.onBindViewHolder (AdapNJ.kt: 22)

Any suggestions?
