Я пытался использовать recycleview во фрагменте, но получаю ошибку «val нельзя переназначить». Я сбит с толку, потому что я не дал никакого значения, я использовал переменную.моя основная деятельность:
class KategoriFragment : Fragment() {
var araclarKategori = ArrayList<AracMarka>()
private lateinit var galleryViewModel: GalleryViewModel
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
galleryViewModel =
ViewModelProviders.of(this).get(GalleryViewModel::class.java)
var root = inflater.inflate(R.layout.fragment_category, container, false)
rvarackategori = root.findViewById(R.id.rvarackategori) as RecyclerView
var MyAdapter = AracMarkaAdapter(araclarKategori)
rvarackategori.adapter = MyAdapter
veriKaynaginiDoldur()
return root
}
fun veriKaynaginiDoldur(): ArrayList<AracMarka> {
var aracLogo = arrayOf(R.drawable.opellogo, R.drawable.chevroletlogo)
var aracismi = resources.getStringArray(R.array.arabaisim)
for (i in 0..araclarKategori.size - 1) {
var eklenecekaracKategori = AracMarka(aracismi[i], aracLogo[i])
araclarKategori.add(eklenecekaracKategori)
}
return araclarKategori
}
}
Это мой адаптер:
class AracMarkaAdapter(tumKategori: ArrayList<AracMarka>) :
RecyclerView.Adapter<AracMarkaAdapter.AracMarkaViewHolder>() {
var araclar = tumKategori
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): AracMarkaViewHolder {
var inflater = LayoutInflater.from(parent.context)
var arackategori = inflater.inflate(R.layout.arac_kategori, parent, false)
return AracMarkaViewHolder(arackategori)
}
override fun getItemCount(): Int {
return araclar.size
}
override fun onBindViewHolder(holder: AracMarkaViewHolder, position: Int) {
holder.aracismi.text=araclar.get(position).aracAdi
holder.aracLogo.setImageResource(araclar.get(position).aracLogo)
}
class AracMarkaViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var teksatirKategori= itemView
var aracismi= teksatirKategori.tvaracAdi
var aracLogo=teksatirKategori.img_arac_sembol
}
}
