here is my adapter:-not posting full code just an important part

override fun onBindViewHolder(holder: MyViewHolder, position: Int) {

    holder.productname.text = Tablelist.get(position).name
    holder.producername.text = Tablelist.get(position).producer

    holder.productprice.text = Tablelist.get(position).cost.toString()

    Glide.with(context).load(Tablelist.get(position).product_images)
        .into(holder.image)
    holder.rate.setRating(Tablelist.get(position).rating);
 //   holder.rate.setStepSize(Tablelist.get(position).rating);// to show to stars


    holder.itemView!!.setOnClickListener {


        val context:Context=holder.itemView.context
        val i=Intent(context,
            Product_details::class.java)
        i.putExtra("id",Tablelist.get(position).id.toString())
      Log.e("checkid",Tablelist.get(position).id.toString())
        context.startActivity(i)
    }
}

fun setMovieListItems(movieList: List<Table_data>){
    this.Tablelist = movieList;
    notifyDataSetChanged()
}

class MyViewHolder(itemView: View?) : RecyclerView.ViewHolder(itemView!!) {

    val productname: TextView = itemView!!.findViewById(R.id.title)
    val producername: TextView = itemView!!.findViewById(R.id.title1)
    val productprice: TextView = itemView!!.findViewById(R.id.title2)
    val rate: RatingBar=itemView!!.findViewById(R.id.ratingbar)

    val image: ImageView = itemView!!.findViewById(R.id.image)

}

here is my Tablelist:

data class Table_data (

@SerializedName("id") val id : Int,
@SerializedName("product_category_id") val product_category_id : Int,
@SerializedName("name") val name : String,
@SerializedName("producer") val producer : String,
@SerializedName("description") val description : String,
@SerializedName("cost") val cost : Int,
@SerializedName("rating") val rating : Float=0.0f,
@SerializedName("view_count") val view_count : Int,
@SerializedName("created") val created : String,
@SerializedName("modified") val modified : String,
@SerializedName("product_images") val product_images : String
)

Not sure but here problem might be with the float conversion from json adapter. what you can do is get the field as String, so the value is not lost at the time of conversion.

@SerializedName("rating") val rating : String,

now in your adapter try to convert this to float.

 holder.rate.setRating(Tablelist.get(position).rating.toFloat())

can you try this one.
