Why doesn't my ImageView as a button work?-CodePudding

I'm trying to make an ImageView button inside a fragment to open another fragment in a navigation drawer but I have encountered a problem where I can't set an OnCliCkListener to my ImageView button. I tried searching fixes on youtube but I can't seem to find a fix to my problem.

Here's the error Here's the error as text

HomeFragment.java

public class HomeFragment extends Fragment {
private FragmentHomeBinding binding;


public View onCreateView(@NonNull LayoutInflater inflater,
                         ViewGroup container, Bundle savedInstanceState) {
    
    binding = FragmentHomeBinding.inflate(getLayoutInflater());
    return binding.getRoot();
}

public void onViewCreated(View view, Bundle savedInstanceState){
    super.onViewCreated(view, savedInstanceState);

    binding.IVOrdersButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Fragment OrdersFragment = new OrdersFragment();
            FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.replace(R.id.nav_dashboard, OrdersFragment);
            fragmentTransaction.addToBackStack(null);
            fragmentTransaction.commit();

        }
    });
}
public void onDestroy(){
    super.onDestroy();
    binding = null;
  }

CodePudding user response：

You're inflating FragmentHomeBinding based on fragment_home.xml but the layout with the imageview is called Dashboard_fragment.xml. Move the ImageView to fragment_home.xml to be able to use it this way.

Check the code again, it is missing @Override before the onCreateView and onViewCreated functions
