Fragment class where only toolbar initialised by me
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_word_recyclerview,container,false);
Toolbar toolbar = ((Toolbar) view.findViewById(R.id.toolbar));
AppCompatActivity activity = (AppCompatActivity) getActivity();
activity.setSupportActionBar(toolbar);
setHasOptionsMenu(true);
return view;
In the "Crud Sql xml", towards the end - you have:
<include layout="@layout/fragment_word_recyclerview" />
You may want to remove this line.
If you see the second code snippet, this layout has toolbar and a recyclerview. If you include this layout in "Crud Sql xml", you will see the toolbar on top. The recyclerview may not be visible because you may not have added any content into it.
