    android:id="@+id/toolbar"

    </RelativeLayout>

If you are using new androidx implementations, when typing Toolbar, the Studio will autocomplete it to android.support.v7.widget.Toolbar, but you should use androidx.appcompat.widget.Toolbar instead, otherwise you will get this error.


Sorry Guys. I have solved this Issue long ago. I did a lot of changes. So I can't figure out which one does the trick.

  1. I have changed the id as suggested by Jared Burrows.

  2. Removed my support library and cleaned my project and Re added it.

  3. Go to File -> Invalidate Caches/Restart.

Hope it works.

This is how my code looks now
