If you want to change your toolbar from a fragment, the code below may help you.

Add toolbar in your fragment XML and then you can change the toolbar of your activity like this:

 Toolbar toolbar = view.findViewById(R.id.toolbar);
 ((MainActivity) getActivity()).getSupportActionBar().hide();

 ((MainActivity) getActivity()).setSupportActionBar(toolbar);

  • When an event occurs and you want to perform a menu update, you must call invalidateOptionsMenu() to request that the system call onPrepareOptionsMenu().
  • However, you should use onCreateOptionsMenu() only to create the initial menu state and not to make changes during the activity lifecycle.
  • If you want to modify the options menu based on events that occur during the activity lifecycle, you can do so in the onPrepareOptionsMenu() method. This method passes you the Menu object as it currently exists so you can modify it, such as add, remove, or disable items. (Fragments also provide an onPrepareOptionsMenu() callback.)
