title: Is there any way to customize an activity toolbar in it's fragments?
body: <p>I have a main activity and several fragments. Fragments are called through a bottom navigation . My goal is to define a main toolbar in the main activity that has a different views in each of the fragments; This means that its title and even the icons and menus inside it should be unique in each fragment. After a lot of searching, I figured oute that it is possible to change the title of the format, but I did not come to a conclusion about the rest of the cases. Is there a way other than defining dedicated toolbar for each fragment?</p>
