OUTPUT
The size of folderList is 2
I also check the size of adapter. It is also 2
I also tried by making a new Adapter but it also does not work.
I don't know where I am making mistake and why it is now showing nothing in activity.

Change 1 :
In the xml set attribute android:layout_width="0dp" to android:layout_width="match_parent" and android:layout_height="0dp" to android:layout_height="match_parent"
Change 2 :
In your MainActivity code set LayoutManager to the RecyclerView before setting up adapter. so the code goes this way :
//Defining RecyclerView and setting LayoutManager
RecyclerView recyclerView = binding.folderRecyclerView;
FolderListAdapter adapter = new FolderListAdapter(this, folderList);
//Setting up Adapter
recyclerView.setLayoutManager(new GridLayoutManager(this, 2));
recyclerView.setAdapter(adapter);

Fragment viewpager No adapter attached; skipping layout

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);

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);

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.

RecyclerView: No adapter attached; skipping layout and java.lang.NullPointerException

I keep getting the error "E/RecyclerView: No adapter attached; skipping layout" when the RecyclerView list is shown. I'm getting data correctly from API but I got "void android.widget.TextView.setText(java.lang.CharSequence)' on a null object reference"
I know this question has been asked a lot before but I checked most of the questions and none has worked for me.
This is my fragment:
public class HomeFragment extends Fragment {
private View view;
private RecyclerView recyclerView;
private ArrayList<Result> arrayList;
private SwipeRefreshLayout refreshLayout;
private PostAdapter postAdapter;
private MaterialToolbar toolbar;
private SharedPreferences userPref;
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
view = inflater.inflate(R.layout.layout_home,container,false);
return view;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
init();
}
private void init() {
userPref = getContext().getApplicationContext().getSharedPreferences("user", Context.MODE_PRIVATE);
recyclerView = (RecyclerView)view.findViewById(R.id.recyclerHome);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
refreshLayout = (SwipeRefreshLayout)view.findViewById(R.id.swipeHome);
toolbar =(MaterialToolbar) view.findViewById(R.id.toolbarHome);
((HomeActivity)getContext()).setSupportActionBar(toolbar);
getResults();
refreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
getResults();
}
});
}
private void getResults() {//Working Fine}
}
My adapter:
public class PostAdapter extends RecyclerView.Adapter<PostAdapter.PostsHolder>{
private ArrayList<Result> list;
private Context context;
public PostAdapter(Context context, ArrayList<Result> list) {
this.list = new ArrayList<Result>(list);
this.context = context;
}
#NonNull
#Override
public PostsHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_home, parent, false);
return new PostsHolder(view);
}
#Override
public void onBindViewHolder(#NonNull PostsHolder holder, int position) {
Result result = list.get(position);
holder.imgPostDate.setText(result.getDate());
}
#Override
public int getItemCount() {
return list.size();
}
public static class PostsHolder extends RecyclerView.ViewHolder{
private TextView imgPostProfile,imgPostName,imgPostDate;
private ImageButton btnPostOption;
public PostsHolder(#NonNull View itemView) {
super(itemView);
imgPostProfile =(TextView) itemView.findViewById(R.id.imgPostProfile);
imgPostName = (TextView)itemView.findViewById(R.id.imgPostName);
imgPostDate =(TextView) itemView.findViewById(R.id.imgPostDate);
btnPostOption =(ImageButton) itemView.findViewById(R.id.btnPostOption);
}
}
}
I modified my code according to the answers I found to similar questions but none of them worked.

In onCreateViewHolder you inflated the wrong xml. It should've been R.layout.layout_post
#NonNull
#Override
public PostsHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_post, parent, false);
return new PostsHolder(view);
}

To prevent from error E/RecyclerView: No adapter attached; skipping layout, you should call recyclerView.setAdapter(adapter); inside your init(); method.
Then after you have your data you should notify the adapter in order to display your data by calling adapter.notifyDataSetChanged(); or using any other notify methods. Check this answer for other notify methods.

If your getResults() is where you're calling your recyclerview.setAdapter(), you're calling setAdapter too late. You need to make sure your adapter is set during onCreateView() so that the Recyclerview isn't being skipped while drawing the layout.

No Adapter Attached; Skipping layout:
you should setadapter in your main thread methods of fragment; then add or update data to adapter
Nullpointer at settext [at adapter]: In onCreateViewHolder you inflated the wrong xml. It should be R.layout.layout_post instead of R.layout.layout_home

Fetch Data From DB and Display It in a Viewpager In A recyclerview

Before marking as duplicate et al, viewpager from recyclerview is kind of triccky. The code is able to retrieve data from db and display it in a recyclerview with cardview. I want to be able to scroll the images in the viewpager while in the recyclerview as shown in the wireframe below, the dots represent number of images retrieved from DB which should be swipeeable right or left. Imageview seems not to be swipeable.

Native Ad Admob to Custom List Adapter in Android

I'm struggling to find a way to add a native ad within my app on Android.
MainActivity Class:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tab1, container, false);
final String[] numbers = {"one","two", "", "three", "four", "five","six","seven" "eight","nine", "ten" "eleven","twelve", "thirteen"};
Integer[] images = {0,1,2,3,4,5,6,7,8,9,10,11,12,13
};
CustomListAdapter adapter=new CustomListAdapter(this.getActivity(), mobileArray, images);
NativeExpressAdView adView = (NativeExpressAdView) rootView.findViewById(R.id.adView);
AdRequest request = new AdRequest.Builder().build();
adView.loadAd(request);
list=(ListView) rootView.findViewById(R.id.list_view);
list.setAdapter(adapter);
CustomListAdapter Class:
public class CustomListAdapter extends ArrayAdapter<String> {
private final Activity context;
private final String[] numbers;
private final Integer[] imgid;
public CustomListAdapter(Activity context, String[] numbers, Integer[] imgid) {
super(context, R.layout.listv, itemname);
// TODO Auto-generated constructor stub
this.context=context;
this.numbers=numbers;
this.imgid=imgid;
}
public View getView(int position,View view,ViewGroup parent) {
LayoutInflater inflater=context.getLayoutInflater();
View rowView=inflater.inflate(R.layout.listv, null,true);
NativeExpressAdView adView = (NativeExpressAdView) rowView.findViewById(R.id.adView);
TextView txtTitle = (TextView) rowView.findViewById(R.id.number);
ImageView imageView = (ImageView) rowView.findViewById(R.id.imgid);
TextView extratxt = (TextView) rowView.findViewById(R.id.textView1);
txtTitle.setText(numbers[position]);
imageView.setImageResource(imgid[position]);
extratxt.setText("Number: "numbers[position]);
return rowView;
};
}
I want to add the native add within a particular index in array, ideally where it shows "". I'm trying to add the adView into the adapter but unsure how to do this.
