I am using recyclerview to display images in cardview. When I load images from the url. It loads well from first time but when It loads for second time it is not displayed properly.



This is how it is loaded second time



How to fix it? Here is the code



override fun getItemCount(): Int {

dataList = FlickrDBOperation.dataArray
if (dataList!!.isEmpty())
return 0

Log.e("count",dataList!!.size.toString())
return dataList!!.size

}

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): Holder {

var itemView: View = LayoutInflater.from(parent.context).inflate(R.layout.imagelist_row,parent,false)
var viewHolder: FlickrAdapter.Holder = FlickrAdapter.Holder(itemView)


return viewHolder

}

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

holder.image_name.text = dataList!!.get(position).name
Picasso.with(context).load(dataList!!.get(position).preUrl).into(holder.row_image)

}


class Holder(itemView: View?) : RecyclerView.ViewHolder(itemView) {

val row_image: ImageView
val image_name: TextView
init {
row_image = itemView!!.findViewById<ImageView>(R.id.row_image)
image_name = itemView!!.findViewById<TextView>(R.id.image_name)
}

}

  • Does the dataArray from dataList change from time to time? Cause getItemCount() is called a lot and maybe the bug gets in there somehow.

  • No it is filled once only when fragment is created
