I have tried the below code in my fragment class but it is not working and also not showing any error,i have given both the adapter class code and fragment class code please tell where i have mistaken what is happening that when i run the code it is not showing even the search bar on the fragment
//Fragment class code
public class PharmacyPatientFragment extends Fragment {
PharmacyAdapter Adapter;
private FragmentPharmacyPatientBinding binding;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

Adapter = new PharmacyAdapter(dataqueue());
binding.recylerviewPharmacy.setAdapter(Adapter);
return binding.getRoot();

You need to convert a loop counter to string using str, include the value in a list, use the multiplication operator to repeat the value in the list, and then use the string join function to insert the spaces. Here's an example. If you want to start with 1 1 1 and not just 1 like I do here, then print(' '.join((i + 2) * [str(i)])) instead of what is shown
>>> for i in range(1, 6):
... print(' '.join(i*[str(i)]))
...
1
2 2
3 3 3
4 4 4 4
5 5 5 5 5
