My app works fine, it loads data in the recyclerView. But, there is always an error in the Logcat as No adapter attached; skipping layout.
Following is my code, can you tell me where to make what change.
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setHasOptionsMenu(true)
}
onCreateView method
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
binding = FragmentDashboardBinding.inflate(inflater, container, false)
binding.fbDashboard.setImageResource(R.drawable.ic_grid_view)
binding.fbDashboard.setOnClickListener {
if (newView == "ListView") {
newView = "GridView"
fb_dashboard.setImageResource(R.drawable.ic_list_view)
} else {
newView = "ListView"
fb_dashboard.setImageResource(R.drawable.ic_grid_view)
}
onResume()
}
getAppDetails()
return binding.root
}
The following function is called after getting the data from the Firestore
fun successDashboardItemsList(dashboardItemsList: ArrayList<Product>) {
hideProgressDialog()
if (dashboardItemsList.size > 0) {
rv_dashboard_items.visibility = View.VISIBLE
tv_no_dashboard_items_found.visibility = View.GONE
rv_dashboard_items.layoutManager =
StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL)
rv_dashboard_items.setHasFixedSize(true)
val adapter = DashboardItemsListAdapter(
requireActivity(),
dashboardItemsList,
newView
)
rv_dashboard_items.adapter = adapter
adapter.setOnClickListener(object :
DashboardItemsListAdapter.OnClickListener {
override fun onClick(position: Int, product: Product) {
val intent = Intent(context, ProductDetailsActivity::class.java)
intent.putExtra(Constants.EXTRA_PRODUCT_ID, product.product_id)
intent.putExtra(Constants.EXTRA_PRODUCT_OWNER_ID, product.user_id)
startActivity(intent)
}
})
} else {
rv_dashboard_items.visibility = View.GONE
tv_no_dashboard_items_found.visibility = View.VISIBLE
}
}
EDIT:
Before marking this as duplicate and voting down: I have seen many questions like this here, but I am not able to do it as the other posts say. I do not know how to do it, I have to get data from the Firestore to populate the recyclerView. Yet, I tried the following. I tried to add the following code in my onCreate DashFragment.kt But my app crashes with the following error.
val dashboardItemsList: ArrayList<Product> = ArrayList()
rv_dashboard_items.visibility = View.VISIBLE
tv_no_dashboard_items_found.visibility = View.GONE
rv_dashboard_items.layoutManager =
LinearLayoutManager(context)
rv_dashboard_items.setHasFixedSize(true)
val adapter = DashboardItemsListAdapter(
requireActivity(),
dashboardItemsList,
newView
)
rv_dashboard_items.adapter = adapter

I am using dataBinding in Kotlin
private lateinit var binding: FragmentDashboardBinding
