RadioButton items not resetting in RecyclerView

RadioButton items not resetting in RecyclerView - android

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
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:layout_marginBottom="5dp"
android:textColor="#color/black"
android:layout_gravity="center|bottom"

The recycler looks like this:
<?xml version="1.0" encoding="utf-8"?>
<androidx.appcompat.widget.LinearLayoutCompat
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="3dp"

/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/fps"

</androidx.appcompat.widget.LinearLayoutCompat>
The code for the adapter looks like this.
class ResolutionRVAdapter(private val sharedNavAndMenuViewModel: SharedNavAndMenuViewModel,
private val lastResolutionSelected: String,
private val capabilityDataList: List<CameraCapabilitySpecificFPS>) : RecyclerView.Adapter<CameraResolutionRVAdapter.ViewHolder>(){
private var lastCheckedPosition = -1
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): CameraResolutionRVAdapter.ViewHolder {
val v = LayoutInflater.from(parent.context).inflate(R.layout.camera_resolution_recycler_item, parent, false)
val viewHolder = ViewHolder(v)
Timber.i("Added viewHolder: ${viewHolder.resolutionText.text}")
return ViewHolder(v)
}
inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView){
val resolutionRadioButton : RadioButton = itemView.findViewById(R.id.resolutionRVRadioButton)
val resolutionText : TextView = itemView.findViewById(R.id.resolutionRVTV)
val framesPerSecondText : TextView = itemView.findViewById(R.id.framesPerSecondRVTV)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val child = capabilityDataList[position]
Timber.i("onBindViewHolder currently working with resolution ${child.resolution} range of $child.range")
holder.resolutionText.text = child.resolution.toString()
holder.framesPerSecondText.text = child.fps
Timber.d("OnBindViewholder and lastResolutionSelected = $lastResolutionSelected")
if(lastResolutionSelected.isEmpty()) {
if(position == 0) {
holder.resolutionRadioButton.isChecked = true
Timber.i("No last resolution was selected. Setting index 0 to true")
}
} else if(lastResolutionSelected == holder.resolutionText.text.toString()) {
Timber.i("An old resolution of ${holder.resolutionText.text} was selected. Setting index $position to true")
holder.resolutionRadioButton.isChecked = true
}
holder.resolutionRadioButton.setOnClickListener {
Timber.i("Index hit was: $position resolution at that index was: ${holder.resolutionText.text}")
if(holder.resolutionRadioButton.isChecked) {
//Button was already checked...must be the same button hit before...nothing to do
} else {
holder.resolutionRadioButton.isChecked = true
runOnUiThread {
notifyItemChanged(lastCheckedPosition)
notifyItemChanged(position)
}
lastCheckedPosition = position
}
}
}
override fun getItemCount(): Int {
return capabilityDataList.size
}
}
Can anyone tell me what it is I'm doing wrong?

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

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.

RecyclerView doesn't display all data

I am working on an application with multiple recycler views inside a fragment. Everything is working properly, except from one recycler view which doesn't display all data. I get the data after an API call, and I have already checked that they are loaded successfully. Any help would be much appreciated, thank you in advance!!

Then, here is the adapter giving the card view the values:
class ProductsAdapter(private val products: List<Product>) :
RecyclerView.Adapter<ProductsAdapter.ViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int) : ViewHolder {
val view = LayoutInflater.from(parent.context)
.inflate(R.layout.view_layout_featuredproduct_row, parent, false)
view.layoutParams.height = (parent.measuredWidth - 40)/2 + 30
view.requestLayout()
return ViewHolder(view)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
holder.bindProduct(products[position])
}
override fun getItemCount(): Int = products.size
class ViewHolder(view: View) : RecyclerView.ViewHolder(view) {
private val image = view.findViewById<ShapeableImageView>(R.id.ivFeaturedProduct)
private val featuredProductTitle = view.findViewById<TextView>(R.id.textViewProductTitle)
private val category = view.findViewById<TextView>(R.id.textViewCategory)
private val featuredProductDuration = view.findViewById<TextView>(R.id.textViewDurationValue)
private val language = view.findViewById<TextView>(R.id.textViewLanguageValue)
private val averageRating = view.findViewById<TextView>(R.id.ratingValue)
private val ratingcount = view.findViewById<TextView>(R.id.ratingCount)
private val pricevalue = view.findViewById<TextView>(R.id.priceValue)
private val context = view.context
private val resources = view.resources
fun bindProduct(product: Product) {
with(product) {
val uri = this.header_image
Picasso.get().load(uri).
placeholder( R.drawable.progress_animation ).
transform(ColorFilterTransformation(ContextCompat.getColor(context, R.color.colorOverlay))).
into(image)
val categoryHelper = this.sku
if (categoryHelper[0].equals('S')){
category.text = resources.getString(R.string.skipTheLineTours)
category.setBackgroundResource(R.drawable.label_skipthelinetour)
category.setTextColor(resources.getColor(R.color.colorSkipTheLineTourTxt))
}
if (categoryHelper[0].equals('A')){
category.text = resources.getString(R.string.audioTours)
category.setBackgroundResource(R.drawable.label_audiotour)
category.setTextColor(resources.getColor(R.color.colorAudioTourTxt))
}
if(categoryHelper[0].equals('V')){
category.text = resources.getString(R.string.virtualTours)
category.setBackgroundResource(R.drawable.label_virtualtour)
category.setTextColor(resources.getColor(R.color.colorVirtualTourTxt))
}
featuredProductTitle.text = this.title
featuredProductDuration.text = this.duration+" minutes"
language.text = languages.size.toString()+" languages"
//category.text = this.sku
averageRating.text = this.average_rating
ratingcount.text = "("+this.rating_count.toString()+")"
pricevalue.text = this.retail_price.toString()+"€"
}
}
}
}
And last but not least, here is the code generating the recycler view:
class ExploreFragment : Fragment() {
private lateinit var viewProductsAdapter: ProductsAdapter
private val model: ProductsViewModel by activityViewModels()
private lateinit var featuredProducts: MutableList<Product>
private lateinit var viewManager : LinearLayoutManager
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_explore, container, false)
}
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
loadFeaturedProducts()
}
private fun loadFeaturedProducts() {
if(!NetworkState().isNetworkAvailable(this#ExploreFragment.context!!.applicationContext)){
return;
}
featuredProducts = mutableListOf()
val recyclerView = rvExploreFragmentFeaturedProducts
viewProductsAdapter = ProductsAdapter(this.featuredProducts)
viewManager = LinearLayoutManager(this.context, LinearLayoutManager.VERTICAL, false)
recyclerView.layoutManager = viewManager
//recyclerView.setHasFixedSize(true)
recyclerView.adapter = viewProductsAdapter
Timber.i("Fragment: load featured products")
model.getProducts().observe(viewLifecycleOwner, { products->
if(products.status == Status.SUCCESS) {
this.featuredProducts.addAll(products.data!!)
viewProductsAdapter.notifyDataSetChanged()
}else {
Timber.i("Featured Products message: "+products.message)
Snackbar.make(view!!, "Cannot load featured products! Error:"+products.message, Snackbar.LENGTH_LONG).show()
}
})
}
}

Thank you for your answers - I figured out my mistake:
I couldn't see anything that was below the ImageView inside my CardView, even though it loaded correctly.
On ProductsListAdapter I forgot to remove an unnecessary calculation:
view.layoutParams.height = (parent.measuredWidth - 40)/2 + 30
view.requestLayout()
which was what caused the problem!

Instead of using the following code:
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/rvExploreFragmentFeaturedProducts"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="30dp"
>
</androidx.recyclerview.widget.RecyclerView>
Please update it with
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/rvExploreFragmentFeaturedProducts"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="30dp"
/>
the Reason you are not getting data is tags! You are not closing tag of Recycler View instead you are creating a new scope to add more things in it like we do with Layouts.
So remove : </androidx.recyclerview.widget.RecyclerView> and add "/" to the closing tag of recycler view or just simply copy and paste my code above

Kotlin Android onClickListener in getView only works on edge

I'm new to Kotlin and Android development in general. I have created a custom adapter that extends BaseAdapter and it works as I want it to, but as soon as I was to add a click listener to the view that gets returned in the getView, it doesn't seem to work as expected.
I have looked everywhere for an answer. I have seen people talking about clickable, duplicateParentState, focusable,... But nothing seems to work
The click listener does react if I click on the left/right border of my layout RelativeLayout, but I want the entire RelativeLayout to react when I click.
Am I missing something in my XML? Or is there some kind of "hack" that works. I'm a little confused as to why my click listener is not working as expected
My TokenAdapter (extends BaseAdapter)
class TokenAdapter(private val ctx: Context) : BaseAdapter() {

var seconds: Int
var percentage: Int = 100
var shouldGenerateToken: Boolean = true

So I managed to fix my problem.
I did 2 "major" things after which my problem was resolved:
I rewrote my list_item.xml making use of LinearLayout instead of RelativeLayout (although I doubt this did anything)

I moved my ClickListener from my Adapter getView() to my MainActivity with an setOnItemClickListener on my ListView
val listview = findViewById<ListView>(R.id.tokenList)
listview.setOnItemClickListener { parent: AdapterView<*>, view: View, position: Int, id ->
val token = tokenAdapter.getItem(position)
if(token != null) {
val code = token.generateCode()
val clip: ClipData = ClipData.newPlainText("2FA Code", code)
clipboardManager.setPrimaryClip(clip)
Toast.makeText(this, "Copied: $code", Toast.LENGTH_LONG).show()
}
}
Using this method on my Listview I also didn't have to use clickable, or any of those kinds of properties on my XML layouts. If someone knows what exactly made it work, please tell me. Personally I think it is the Listener being an 'OnItemClick' and it being moved to the MainActivity, although don't take my word for it as it could just be something else random that I did.

Flicker at top of recycler view

I can see a flicker within my recycler view right at the top. The flicker seems to resemble the top lines of my drawable shapes in the recycler view item.xml. I have made various adjustments to lines and other things to see if I could prevent the flicker but nothing appears to be working.
Here is my code;

Your issue is arising because in your my_item.xml
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="55dp" <---- Fixed Height
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:background="#ae7f9c"
android:gravity="center_vertical">
and in your textviews like this one,
<TextView
android:id="#+id/TV_RV_ID"
android:layout_width="0dp"
android:layout_height="match_parent" <------ this hiding the background try using wrap_content
android:layout_margin="0dp"
android:gravity="center"
android:textAlignment="center"
app:layout_constraintEnd_toStartOf="#+id/TV_RV_DIFFICULTY"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintHorizontal_weight="1"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
To solve this,
Try not giving a fixed height from my_item.xml container, use wrap_content
Add padding to the container constaintlayout
add android:layout_height="wrap_content" to your text views and center_vertical them,
then your issue will resolve, hope this helps
try not giving a fixed height to the container

As you can see, the click area has some margin bottom that I can't understand why happens. Sometimes it happens and sometimes it doesn't and I can't figure out what wrong.
As for the extension function that I am using - I am using it for the entire application

In your first LinearLayout you have defined android:padding="10dp". I assume this causes the unwanted margin.
