I'm making a recipe search application using forkify API. I get such json (let's take pizza recipes for example). I've made a recycler and searchable, but the recipes themselves are given as a link to the site with that recipe (see source_url in the json). I've made a webview for this, but there's one problem. I need to get that source_url and have it match the recipe I clicked on. I tried to make an additional element in resycler, small invisible textview, and put source_url there, so when I clicked on it, it would take text and pass it to a variable and load it as url into webview. (Very silly solution, but I didn't think of another one.) It's not what I had in mind. Basically my code works, but the url is not passed from all textViews. I've been observing its behaviour and I can only assume that it loads every 4 in vertical mode and every 2 in horizontal mode. And this is not what I need. Please help me to solve this problem. Below is my code:
Adapter:
@JvmOverloads
fun RecyclerView.affectOnItemClicks(
onClick: ((position: Int, view: View) -> Unit)? = null,
onLongClick: ((position: Int, view: View) -> Unit)? = null
) {
this.addOnChildAttachStateChangeListener(
RecyclerItemClickListener(
this,
onClick,
onLongClick
)
)
}
class RecyclerAdapter(
private val dataset: List<Recipe>
)
: RecyclerView.Adapter<RecyclerAdapter.FoodHolder>() {
inner class FoodHolder(view: View) : RecyclerView.ViewHolder(view) {
fun bindRecipe(recipe: Recipe) {
itemView.textView.text = recipe.title
itemView.textView3.text = recipe.publisher
itemView.imageView.load(recipe.image_url) {
// placeholder image is the image used
// when our image url fails to load.
placeholder(R.drawable.ic_baseline_error_24)
}
itemView.helptv.text = recipe.source_url
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerAdapter.FoodHolder {
val view = LayoutInflater.from(parent.context)
.inflate(R.layout.recyclerview_item_row, parent, false)
return FoodHolder(view)
}
override fun onBindViewHolder(holder: RecyclerAdapter.FoodHolder, position: Int) {
holder.bindRecipe(dataset.get(position))
}
override fun getItemCount(): Int = dataset.size
}
The code in the MainActivity where I put the text from that textview into an auxiliary variable and then switch to another activation:
ConstandVar.browser_url = helptv.text.toString()
val intent = Intent(this,BrowserActivity::class.java)
startActivity(intent)

apiService.getRecipe(food).enqueue(object : Callback<requestdata> {

Any help would be much appreciated, thanks in advance!

Please make little bit change to make adapter like that way read most of comment , RecyclerView itemClickListener in Kotlin
create callback listener and return url in main activity
