I have created a fragment and inside that fragment I have a recyclerview but when my fragment is loaded nothing shows and it give me this error "E/RecyclerView: No adapter attached; skipping layout". Below is the code for the adapter and fragment class, any help would be appreciated
Adapter Class:
class ViewAllRecipeAdapter(private val newList: ArrayList<Recipes>) :
RecyclerView.Adapter<ViewAllRecipeAdapter.MyViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
val itemView = LayoutInflater.from(parent.context).inflate(R.layout.view_all_recipe_item, parent, false)
return MyViewHolder(itemView)
}
override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
val currentItem = newList[position]
holder.recipeName.text = currentItem.recipeName
holder.recipeDesc.text = currentItem.recipeDescription
}
override fun getItemCount(): Int {
return newList.size
}
class MyViewHolder(itemview: View) : RecyclerView.ViewHolder(itemview) {
val recipeName: TextView
val recipeDesc: TextView
init {
recipeName = itemView.findViewById<View>(R.id.recipe_name) as TextView
recipeDesc = itemView.findViewById<View>(R.id.recipe_description) as TextView
}
}
}
Fragment Class:
class ViewAllMyRecipesFragment : Fragment() {
private lateinit var recyclerview: RecyclerView
private lateinit var recipeData: ArrayList<Recipes>
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
val view: View = inflater.inflate(R.layout.fragment_view_all_my_recipes, container, false)
recipeData = dummygenerator(10)
recyclerview = view.findViewById<RecyclerView>(R.id.recycler_view_all_recipes)
recyclerview.adapter = ViewAllRecipeAdapter(recipeData)
recyclerview.layoutManager = LinearLayoutManager(view.context)
recyclerview.setHasFixedSize(true)
// Inflate the layout for this fragment
return view
}
private fun dummygenerator(size: Int) : ArrayList<Recipes>{
val list = ArrayList<Recipes>()
for(i in 0 until size) {
val drawable = when (i % 3) {
0 -> "recipeName " +i
1 -> "recipeDescription " + i
else -> "Else " +i
}
val item = Recipes("title $i", "body")
list += item
}
return list
}
}
