This is the fragment class i use to to start the service and update the recycler view of the users location data but the item click of the list doesn’t work properly and only work after 3 or 4 times of clicking…

        val location = locations[position]
        holder.bind(location)

    }

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

    inner class LocationViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {

        private val cityNameTextView: TextView = itemView.findViewById(R.id.city_name)
        private val timeStampTextView: TextView = itemView.findViewById(R.id.time_stamp)
        private val viewButton: Button = itemView.findViewById(R.id.viewButton)
        private val locationLayout: RelativeLayout = itemView.findViewById(R.id.overlay)

        fun bind(location: LocationData) {
            locationNameTextView.text = location.latitude.toString()
            cityNameTextView.text = location.longitude.toString()
            timeStampTextView.text = location.timestamp
            viewButton.setOnClickListener {
                onItemClickListener.onItemClick(location)
            }
            locationLayout.setOnClickListener {
                onItemClickListener.onItemClick(location)
            }
        }
    }
}

This is the adapter class I use…I tried everything i could but the problem still persists…I also update or get data from database in viewmodel.scope which is not in main thread…So I am unable to solve the problem…

I would like the recycler view item to perform the click right away and not after 3 or 4 clicks…Please if anybody could solve, it would be of great help.
