I am migrating from usual RecyclerView to ListAdapter:
abstract class BaseAdapter<T>(
#LayoutRes
val normalLayoutId: Int,
#LayoutRes
val loadingLayoutId: Int = R.layout.progress_loading,
sm: (T, T) -> Boolean,
val itemsCells: ArrayList<T?> = ArrayList()
) : ListAdapter<T, RecyclerView.ViewHolder>(TaskDiffCallbac(sm)) {
val VIEW_TYPE_ITEM = 0
val VIEW_TYPE_LOADING = 1
class ItemViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView)
class LoadingViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView)
fun addData(dataViews: ArrayList<T>) {
itemsCells.addAll(dataViews)
this.submitList(dataViews)
notifyDataSetChanged()
}
override fun getItemViewType(position: Int): Int {
return if (getItem(position) == null) {
VIEW_TYPE_LOADING
} else {
VIEW_TYPE_ITEM
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
return if (viewType == Constant.VIEW_TYPE_ITEM) {
val view =
LayoutInflater.from(parent.context).inflate(normalLayoutId, parent, false)
ItemViewHolder(view)
} else {
val view =
LayoutInflater.from(parent.context).inflate(loadingLayoutId, parent, false)
LoadingViewHolder(view)
}
}
fun addLoadingView() {
itemsCells.add(null)
submitList(itemsCells)
}
fun removeLoadingView() {
if (itemsCells.size != 0) {
itemsCells.removeAt(itemsCells.size - 1)
submitList(itemsCells)
}
}
fun clearItems() {
itemsCells.clear()
submitList(itemsCells)
}
class TaskDiffCallbac<T>(val sm: (T, T) -> Boolean) : DiffUtil.ItemCallback<T>() {
override fun areItemsTheSame(oldItem: T, newItem: T): Boolean {
return sm(oldItem, newItem)
}
#SuppressLint("DiffUtilEquals")
override fun areContentsTheSame(oldItem: T, newItem: T): Boolean {
return oldItem == newItem
}
}
}
but while debugging I get this exception:

I am using kotlin language with android studio. I want to get the properties of the element I clicked in the RecyclerView.
Ben bu kod ile saderc id alabiliyorum
Ex: date
ListAdapter.kt
class ListAdapter(
private val context: Context
) : RecyclerView.Adapter<ListAdapter.ListViewHolder>() {
private var dataList = mutableListOf<Any>()
private lateinit var mListener: onItemClickListener
interface onItemClickListener {
fun onItemClick(position: Int)
}
fun setOnItemClickListener(listener: onItemClickListener) {
mListener = listener
}
fun setListData(data: MutableList<Any>) {
dataList = data
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ListViewHolder {
val view = LayoutInflater.from(context).inflate(R.layout.item_row, parent, false)
return ListViewHolder(view)
}
override fun onBindViewHolder(holder: ListViewHolder, position: Int) {
val question: Questionio = dataList[position] as Questionio
holder.bindView(question)
}
override fun getItemCount(): Int {
return if (dataList.size > 0) {
dataList.size
} else {
return 0
}
}
inner class ListViewHolder(itemView: View, listener: onItemClickListener) :
RecyclerView.ViewHolder(itemView) {
fun bindView(questionio: Questionio) {
itemView.findViewById<TextView>(R.id.txt_policlinic).text = questionio.policlinic
itemView.findViewById<TextView>(R.id.txt_title).text = questionio.title
itemView.findViewById<TextView>(R.id.txt_description).text = questionio.description
itemView.findViewById<TextView>(R.id.txt_date).text = questionio.date
itemView.findViewById<TextView>(R.id.txt_time).text = questionio.time
}
init {
itemView.setOnClickListener {
listener.onItemClick(adapterPosition)
}
}
}
}
My code in onCreateView inside list fragment.Edit
ListFragment
recyclerView.layoutManager = LinearLayoutManager(requireContext())
recyclerView.adapter = adapter
observeData()
adapter.setOnItemClickListener(object : ListAdapter.onItemClickListener {
override fun onItemClick(position: Int) {
showShortToast(position.toString())
}
})
this function is also my observationData(),
I made new edits
private fun observeData() {
binding.shimmerViewContainer.startShimmer()
listViewModel.fetchQuestinData("questions",
requireContext())
.observe(viewLifecycleOwner, {
binding.shimmerViewContainer.startShimmer()
binding.shimmerViewContainer.hideShimmer()
binding.shimmerViewContainer.hide()
adapter.setListData(it)
adapter.notifyDataSetChanged()
})
}
You can pass highOrderFuction into the adapter then setonclickListener for any view you want. Like this:
class ListAdapter(
private val context: Context,
private val onItemClick:(questionio: Questionio)->Unit
) : RecyclerView.Adapter<ListAdapter.ListViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ListViewHolder {
val view = LayoutInflater.from(context).inflate(R.layout.item_row, parent, false)
return ListViewHolder(view,onItemClick)
}
...
inner class ListViewHolder(itemView: View,private val onItemClick:(questionio: Questionio)->Unit) : RecyclerView.ViewHolder(itemView) {
fun bindView(questionio: Questionio) {
//set on any view you want
itemView.findViewById<TextView>(R.id.root_view_id).
setOnClickListener{onItemClick(questionio)}
itemView.findViewById<TextView>(R.id.txt_policlinic).text =
questionio.policlinic
itemView.findViewById<TextView>(R.id.txt_title).text = questionio.title
itemView.findViewById<TextView>(R.id.txt_description).text =
questionio.description
itemView.findViewById<TextView>(R.id.txt_date).text = questionio.date
itemView.findViewById<TextView>(R.id.txt_time).text = questionio.time
}
}
}
I want to make Home screen like Instagram where video will play/pause on horizontal and vertical scrolling.
For that I am using fragment inside viewpager and viewpager inside recyclerview for achieving horizontal and vertical scrolling.
Issue is that for second item of recyclerview view of fragment is not created.
can anyone help me to achieve this functionality.
Thanks in advance.

i'm new in Kotlin and learning this Coding-Language right now.
At the moment i get stuck on the Problem that in my Multi-Level expandablelistview in secondlevel the groupPosition is always "0".
The view shows always 3 times the same objects, but it must be 3 different objects.
The Data comes from a local running SQL-Lite Database and the Databasequery works fine.
Here is my code, I hope you can help me!
