How to replace the "hamburger" toolbar button with a back arrow for a specific fragment?

Question

Android

There is MainActivity with Tollbar and FrameLayout, fragments are changed through NavigationDrawer, everything is standard. In one of the fragments there is a list, when you click on a list element, a new fragment opens with a description of the list element.
It is necessary that in the fragment with the description of the list in the toolbar there was not a "hamburger" button, but a button with an arrow back, which would return back to the fragment with the list, and not open the NavigationDrawer. How to do it?

Answer 1

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); // or if you will do it in a fragment then getActivity().findViewById....
toolbar.setNavigationIcon(R.drawable.icon_close);
icon_close you add to the project yourself
