Firebase图片上传存URL后自动跳转至BottomNavigation问题求助

我用Kotlin开发的App实现了将图片上传至Firebase Storage，上传完成后将图片URL存入Firebase Realtime Database以备后续使用。所有功能均正常，唯独在图片URL存入数据库后，App会自动跳转到BottomNavigationActivity。下面是相关代码，我是Kotlin新手，麻烦帮忙排查，感谢。

跳转至PictureTakingActivity的Adapter类 #

class PrintAdapter(val data: ArrayList<PrintModel>) : RecyclerView.Adapter<PrintAdapter.MyViewHolder>() {

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
        var view = LayoutInflater.from(parent.context).inflate(R.layout.single_row_home, parent, false)
        return MyViewHolder(view)
    }

    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        holder.name.setText(data.get(position).name)
        Picasso.get().load(data[position].image).into(holder.image)
        Log.d("TAG", "The image is: " + data[position].catName)
        var cat = data.get(position).catName

        holder.itemView.setOnClickListener{
            if (cat.equals("photo")){
                val intent = Intent(it.context, PictureTakingActivity::class.java)
                it.context.startActivity(intent)
            }
        }
    }

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

    class MyViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        // Both of these can be used to find id
        var name: TextView = itemView.findViewById(R.id.printName)
        var image = itemView.findViewById<ImageView>(R.id.circleImageView1)
    }
}
