I wanted to make a side menu for my android application. To do this, in MainActivity, I changed the root layout element from ConstraintLayout to DrawerLayout, added my own toolbar, and then wrote the side menu code. But when I started testing the app on my phone, the elements of my start fragment(fragment_start) moved to the right.
I sat all day, but did not understand what was the mistake, where did I screw up?
And there are a couple of questions in connection with this: Why is the hamburger not displayed on the toolbar, although I added the code for this (appBarConfig = AppBarConfiguration(navController.graph,binding.drawerLayout))?
How can I make the side menu open only in the fragment that I need, and not in the whole application?
My code:
