The project consists of uploading data to Firebase, when I enter the app everything goes well, but when I am in the Add frangment, I click an ImageButton to open the phone gallery, I select the photo and show it, but when show it in the layout I get the error, I know it has to do with the RecyclerView but... What do I do?.

Trying to add an onclicklistener to the items in my recycler view, that will use an intent to open another activity. I've tried finding examples, but I can only find examples using Java or Kotlin examples that aren't using viewbinding.
package com.truuce.anotherrvtest
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import androidx.recyclerview.widget.GridLayoutManager
import com.truuce.anotherrvtest.databinding.ActivityHeroBinding
class HeroActivity : AppCompatActivity() {
var binding: ActivityHeroBinding? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityHeroBinding.inflate(layoutInflater)
setContentView(binding?.root)
val adapter = CardAdapter(HeroList.heroList)
binding?.heroRV?.adapter = adapter
binding?.heroRV?.layoutManager = GridLayoutManager(applicationContext, 3)
}
override fun onDestroy() {
super.onDestroy()
binding = null
}
}
package com.truuce.anotherrvtest
import android.content.Context
import android.content.Intent
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.ImageView
import android.widget.TextView

import com.truuce.anotherrvtest.databinding.HeroCardBinding
class CardAdapter(val heroList: List<Hero>) : RecyclerView.Adapter<CardAdapter.MainViewHolder>() {
inner class MainViewHolder(val heroBinding: HeroCardBinding) :
RecyclerView.ViewHolder(heroBinding.root) {
fun bindHero(hero: Hero){
heroBinding.heroNameTV.text = hero.heroName
heroBinding.heroIV.setImageResource(hero.image)
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MainViewHolder {
return MainViewHolder(HeroCardBinding.inflate(LayoutInflater.from(parent.context), parent, false))
}
override fun onBindViewHolder(holder: MainViewHolder, position: Int) {
val hero = heroList[position]
holder.bindHero(hero)
}
override fun getItemCount() = heroList.size
}
tried adding View.OnClickListener to MainViewHolder, then implemented a member. OnClick(p0: View){}, but no idea how to get it working.
You should add a functional property for a click listener in your adapter.
The Activity can set the item click listener behavior.
class CardAdapter(
val heroList: List<Hero>,
val itemClickListener: (Hero)->Unit
) : RecyclerView.Adapter<CardAdapter.MainViewHolder>() {
inner class MainViewHolder(val heroBinding: HeroCardBinding) :
RecyclerView.ViewHolder(heroBinding.root) {
fun bindHero(hero: Hero) = with(heroBinding) {
heroNameTV.text = hero.heroName
heroIV.setImageResource(hero.image)
root.setOnClickListener { itemClickListener(hero) }
}
}
//...
}
// In Activity:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityHeroBinding.inflate(layoutInflater)
setContentView(binding?.root)
val adapter = CardAdapter(HeroList.heroList) { hero ->
// do something with hero item when it's clicked
}
binding?.heroRV?.adapter = adapter
binding?.heroRV?.layoutManager = GridLayoutManager(applicationContext, 3)
}
I have a little problem with baseContext in Fragment, in a nutshell, I'm making an application with Retrofit and RecyclerView, and for practice I decided to make them in Fragment,I took this code from MainActivity and then I ran into a problem that I don't know how to replace baseContext in override fun onResponse, I just replaced it with context and it still doesn't work

For some reason it isn't properly adding the selected item from the recyclerView adapter to the selectedItem variable.
Would appreciate any insight into why this is happening all of a sudden.
It turned out that the error occurred because I was tapping the checkbox itself and not just the card.

Thank you so much in advance !
Move all that layoutManager and stackView stuff from onCreate to onViewCreated because during onCreate your view is not created yet and same is assured in onViewCreated.
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
layoutManager = CardStackLayoutManager(context,this).apply {
setSwipeableMethod(SwipeableMethod.AutomaticAndManual)
setOverlayInterpolator(LinearInterpolator())
}
stack_view.layoutManager = layoutManager
stack_view.adapter = adapter
stack_view.itemAnimator.apply {
if(this is DefaultItemAnimator){
supportsChangeAnimations = false
}
}
}
or you can refer here
