RecyclerView doesn't show any items even though getItemCount() returns the correct count in the adapter

everyone. I have a RecyclerView in which I want to display items. For this I implemented an adapter class and the required functions. I have 3 identical example data sets which I pass to the adapter and which are also correctly displayed as 3 in getItemCount(). However, my problem is that I can't see anything. The RecyclerView remains empty. I also don't get any errors in the terminal/debugger, everything is correct. Have I made a mistake and perhaps forgot something?
Here is my OverviewActivity containing the RecyclerView:
class OverviewActivity : AppCompatActivity() {
private lateinit var resultsAdapter: ResultsAdapter
private lateinit var listResults : ArrayList<HouseModel>
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_overview)
listResults = ArrayList()
var resultRv: RecyclerView = findViewById(R.id.result_rv)
resultRv.layoutManager = LinearLayoutManager(this)
resultsAdapter = ResultsAdapter(this, listResults)
resultRv.adapter = resultsAdapter
//TEST DATA
listResults.add(HouseModel("Abador",R.drawable.house,R.drawable.alle,"Bella Vista, PY","650","Schönes, neu renoviertes Haus. Mit neuestem Standard. Kann besichtigt werden"))
listResults.add(HouseModel("Abador",R.drawable.house,R.drawable.alle,"Bella Vista, PY","650","Schönes, neu renoviertes Haus. Mit neuestem Standard. Kann besichtigt werden"))
listResults.add(HouseModel("Abador",R.drawable.house,R.drawable.alle,"Bella Vista, PY","650","Schönes, neu renoviertes Haus. Mit neuestem Standard. Kann besichtigt werden"))
resultsAdapter.notifyDataSetChanged()
... } }
Model class:
data class HouseModel(
var senderName: String,
var mainImg : Int,
var senderImg: Int,
var place: String,
var price: String,
var desc: String,
)
ResultsAdapter:
class ResultsAdapter(private val context: Context, private val resultsList: ArrayList<HouseModel>): RecyclerView.Adapter<ResultsAdapter.ViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ResultsAdapter.ViewHolder {
val inflateView = LayoutInflater.from(context).inflate(R.layout.result_list_rv,parent,false)
return ViewHolder(inflateView)
}
class ViewHolder(view: View): RecyclerView.ViewHolder(view) {
val mainImg: ImageView = view.findViewById(R.id.rv_list_main_img)
val senderImg: ImageView = view.findViewById(R.id.main_list_rv_sender_img)
val senderName: TextView = view.findViewById(R.id.main_list_rv_sender_name)
val place: TextView = view.findViewById(R.id.main_list_rv_place)
val desc: TextView = view.findViewById(R.id.main_list_rv_desc)
val price: TextView = view.findViewById(R.id.main_list_rv_price)
}
override fun onBindViewHolder(holder: ResultsAdapter.ViewHolder, position: Int) {
holder.mainImg.setImageResource(resultsList[position].mainImg)
holder.senderImg.setImageResource(resultsList[position].senderImg)
holder.senderName.text = resultsList[position].senderName
holder.place.text = resultsList[position].place
holder.desc.text = resultsList[position].desc
holder.price.text = resultsList[position].price
}
override fun getItemCount(): Int {
println("ITEMS: ${resultsList.size}")
// SHOWS I/System.out: ITEMS: 3
return resultsList.size
}
}

I've reviewed your code and I think the problem is in the result_list_rv.xml file,
try to set the main linear layout width = match_parent and last RelativeLayout height = wrap_content

Dynamically add item into recyclerview when button pressed

I am trying to build a layout in which there is a recyclerview where each item has three edittexts horizontally aligned. I want to add the next item when a button is pressed.
This the design I am trying to build
This is the Adapter class for the recycler view
class AddProjectAdapter(private val itemsList : ArrayList<ItemDetails>) : RecyclerView.Adapter<AddProjectAdapter.AddProjectViewHolder>() {
inner class AddProjectViewHolder(private val binding : AddProjectItemViewBinding) : RecyclerView.ViewHolder(binding.root) {
fun bind(item : ItemDetails){
binding.item = item
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): AddProjectViewHolder{
return AddProjectViewHolder(AddProjectItemViewBinding.inflate(LayoutInflater.from(parent.context), parent, false))
}
override fun onBindViewHolder(holder: AddProjectViewHolder, position: Int) {
holder.bind(itemsList[position])
}
override fun getItemCount(): Int = itemsList.size
}

And my recyclerview id is item_details_recyclerview.
Output for the above code
When I click the add button the item added is not visible but the add button moves down.
Can someone help me out with this issue? And also if you could provide some better approach it would be great.
Thanks in advance.

Change height of ConstraintLayout from add_project_item_view.xml
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
to this
<androidx.constraintlayout.widget.ConstraintLayout

RadioButton items not resetting in RecyclerView

This has been asked before but those solutions didn't help me out. I have a RecyclerView that is scrollable and only partially visible on the screen at any one time. It holds a list of RadioButtons and some text related to each item. When you click on a RadioButton, the last button selected prior to this one should turn off. It does not. Each button you click gets selected and the other ones that you selected before stay selected as well.
It's set up like this:
<?xml version="1.0" encoding="utf-8"?>
<androidx.appcompat.widget.LinearLayoutCompat

Can't setOnItemClickListener ListView Kotlin

I have implemented a custom adapter in a ListView but when i try to use setOnItemClickListener the function does not work. I tried using a toast to notify me if the click respond but it did not work
Here is my activity and the adapter
class PasswordListActivity : AppCompatActivity() {
private lateinit var dataSource: SavedPasswordDB
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_password_list)
user = intent.getSerializableExtra("loggedUser") as User
loadPasswords()
btAddOpt.setOnClickListener {
// ...
}
}
override fun onPause() {
super.onPause()
this.loadPasswords()
}
override fun onResume() {
super.onResume()
this.loadPasswords()
}
internal class CustomAdapter(context: Context, data: List<SavedPassword>): ArrayAdapter<SavedPassword>(context, R.layout.activity_password_list, data) {
#SuppressLint("ViewHolder", "SetTextI18n")
private lateinit var dataSource: SavedPasswordDB
override fun getView(position: Int, convertView: View?, parent: ViewGroup): View {
val inflater = LayoutInflater.from(context).inflate(R.layout.custom_row, parent, false)
val pwd = getItem(position)
dataSource = SavedPasswordDB(context)
inflater.tvTitle.text = pwd!!.fromTitle
inflater.tvUser.text = "User: " + pwd.pwdUser
inflater.tvCont.text = "Password: " + pwd.pwdContent
inflater.tvOptLink.text = "Site link: " + pwd.optionalLink
inflater.tvCreated.text = "Created At: " + pwd.createdAt
inflater.btDeleteCurrent.setOnClickListener {
// ...
}
return inflater
}
}
private fun loadPasswords () {
dataSource = SavedPasswordDB(this)
var passwords = mutableListOf<SavedPassword>()
val cursor = dataSource.selectPwdByUser(user.id)
while (cursor.moveToNext()) {
val col = SavedPassword(cursor.getInt(0), cursor.getString(1), cursor.getString(2), cursor.getString(3), cursor.getString(4), cursor.getString(5), cursor.getInt(6))
passwords.add(col)
}
val adapter = CustomAdapter(this, passwords)
lvPwds.adapter = adapter
lvPwds.setOnItemClickListener { adapterView, view, i, id ->

Add below line to your ListViewtag in xml -
android:descendantFocusability="blocksDescendants"

EditText in RecyclerView with Kotlin not working

I'm new in app developpement and I have a problem with an EditText in recyclerview's item.
When user clicks on the editText nothing appens. I tried with an itemClickListener on EditText, click did worked but not edtion of text.
Here is my code :
the Activity :
class MyIngredientListActivity : AppCompatActivity() {
val ingerdientOfListArray = database.getAllIngredientOfList()
val adapter = IngredientOfListAdapter(ingerdientOfListArray)
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.ingredient_list_recyclerview)
findViewById<Button>
(R.id.ingredient_list_activity_search_button).setOnClickListener {
val intent = Intent(this, IngredientSearchableActivity::class.java)
startActivity(intent)
}
val recyclerView = findViewById<RecyclerView>
(R.id.ingredientoflist_recyclerview)
recyclerView.layoutManager = LinearLayoutManager(this)
recyclerView.adapter = adapter
}
override fun onResume() {
super.onResume()
adapter.updateIngredientList()
}
The adapter :
class IngredientOfListAdapter(val ingredientOfListDisplay:

Thanks and have a good day !

I think adding
holder.editText.setOnClickListener(Object : View.OnClickListener {
override fun OnClick(v: View?) {
v.requestFocus()
}
}
Should do the trick. I'm not very good at Kotlin, so there might be a syntax error there.
