Fragment viewpager No adapter attached; skipping layout

Question

I tried a lot of solutions but no solution has worked for me. I am getting data from the server and showing it inside a recycleview. The data shows fine but shows this error in the logcat

Access denied finding property "persist.vendor.log.tel_dbg"
E/RecyclerView: No adapter attached; skipping layout
E/RecyclerView: No adapter attached; skipping layout

sometimes when I refresh again and again the recyclerview becomes empty. I am using viewpager consisting of 2 fragments inside a parent fragment. this recycleview is using in a nested scrollview some time data not showing Code snippet:

homebuyer_adapter_recycler=new homebuyer_adapter_recycle(getActivity(), items);
LinearLayoutManager home = new LinearLayoutManager(getActivity());                         
home.setOrientation(LinearLayoutManager.VERTICAL);                      
allitemsgrid.setLayoutManager(home);
allitemsgrid.setAdapter(r);

Here is more about

          @Override
         public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, 
          final int viewType) {
    View v = LayoutInflater.from(context).inflate(R.layout.items_view,parent, 
             false);
    RecyclerView.LayoutParams lp = new 
         RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);
                 v.setLayoutParams(lp);
              ViewHolder viewHolder = new ViewHolder(v);

Answer 1

In error it is saying that the Adapter for RecylerView is not attached. So, try to add adapter to the layout using:

recyclerView.setAdapter(categoryAdapter);

Answer 2

I am assuming homebuyer_adapter_recycler is your adapter. According to that, you haven't really set your adapter as the logcat is specifying.

Add the below code instead of allitemsgrid.setAdapter(r);

allitemsgrid.setAdapter(homebuyer_adapter_recycler);

If my assumption or suggestion is wrong, it is okay. It is probably because your question is not very clear and does not provide the necessary details. Please provide more details such as the adapter class code and what is allitemsgrid , homebuyer_adapter_recycler and r .
