Code of HomeFragment
package com.example.booksh
import android.os.Bundle
import android.view.View
import androidx.fragment.app.Fragment
import androidx.recyclerview.widget.LinearLayoutManager
import androidx.recyclerview.widget.RecyclerView
import com.example.booksh.databinding.FragmentHomeBinding
class HomeFragment: Fragment(R.layout.fragment_home) {
private lateinit var binding: FragmentHomeBinding

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
binding = FragmentHomeBinding.inflate(layoutInflater)
super.onViewCreated(binding.root, savedInstanceState)
// Поисковой список
imageId = arrayOf(
R.drawable.a,

"Война и мир",
"Капитанская дочка",
"Раковый корпус",
"Мастер и маргарита",
"Муму",

"Скотный двор",
"Портрет Дориана Грея",

//Переменные для выпадающего списка на главной странице - поиск книг
newRecyclerView = binding.recyclerView
newRecyclerView.layoutManager = LinearLayoutManager(this.context)
newRecyclerView.setHasFixedSize(true)

//Заносим в список данные о книгах
private fun getUserData() {
for (i in imageId.indices){
val book = Books(imageId[i], heading[i])
newArrayList.add(book)
}
newRecyclerView.adapter = MyAdapter(newArrayList)
}
}
Code of adapter
package com.example.booksh
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.TextView
import androidx.recyclerview.widget.RecyclerView
import com.google.android.material.imageview.ShapeableImageView
class MyAdapter(private var booksList: ArrayList<Books>) : RecyclerView.Adapter<MyAdapter.MyViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
val itemView = LayoutInflater.from(parent.context).inflate(R.layout.list_item,
parent, false)
return MyViewHolder(itemView)
}
override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
val currentItem = booksList[position]
holder.titleImage.setImageResource(currentItem.titleImage)
holder.tvHeading.text = currentItem.heading
}
override fun getItemCount(): Int {
return booksList.size
}
class MyViewHolder(itemView: View): RecyclerView.ViewHolder(itemView){
val titleImage : ShapeableImageView = itemView.findViewById(R.id.list_item_icon)
val tvHeading: TextView = itemView.findViewById(R.id.list_item_text)
}
}
I made a ricycle view for main activity without visibility change, but it was shown in every fragment of my app. Then I copied all code connected with recyclerView to fragment home (xml, kt), but it became invisible whether I click on the search field or not.
