Travel Booking App

This error is occurring because you're trying to use R.id.menu_info in a switch statement, but it's not being recognized as a constant expression. This is happening because the context menu is not properly connected to your fragment.
Let's fix this by modifying your BookTicketFragment class to properly handle the context menu. Here's what we need to change:

First, we need to register the context menu with the fragment's view
Then, we need to provide proper implementation of the onCreateContextMenu method
Finally, we need to fix the onContextItemSelected method
// BookTicket Fragment
public static class BookTicketFragment extends Fragment {
private boolean isTicketBooked = false;
private String bookingDetails = "";

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    if (isTicketBooked) {
        return inflateTicketDetailsView(inflater, container);
    } else {
        return inflateBookingFormView(inflater, container);
    }
}

private View inflateBookingFormView(LayoutInflater inflater, ViewGroup container) {
    View view = inflater.inflate(R.layout.fragment_book_ticket, container, false);

    // All other initialization code remains the same

    // Register context menu
    TextView tvContextMenu = view.findViewById(R.id.tvContextMenu);
    registerForContextMenu(tvContextMenu);

    return view;
}

// Add this method to create the context menu
@Override
public void onCreateContextMenu(android.view.ContextMenu menu, View v, android.view.ContextMenu.ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    android.view.MenuInflater inflater = getActivity().getMenuInflater();
    inflater.inflate(R.menu.context_menu, menu);
}

// Modify this method to handle the menu item selection
@Override
public boolean onContextItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.menu_info:
            Toast.makeText(getContext(), "Travel information", Toast.LENGTH_SHORT).show();
            return true;
        case R.id.menu_help:
            Toast.makeText(getContext(), "Help center", Toast.LENGTH_SHORT).show();
            return true;
        default:
            return super.onContextItemSelected(item);
    }
}

// The rest of your code remains the same

}
