I am trying to access navigation drawer so that when i click on the top left corner of app bar, I can access settings in a new activity. Right now what I get when I click on the upper left corner and then click settings is the menu retracts and nothing else happens. I have a bottom navigation bar also. Please help. Here's what I have so far:

Just change the activity_navigation.xml to
<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout
...>
<RelativeLayout...>
<com.google.android.material.navigation.NavigationView
android:layout_gravity="start"
.../>
</androidx.drawerlayout.widget.DrawerLayout>
Also you have to handle the click on the settings item with navigationView.setNavigationItemSelectedListener.
About the DrawerLayout check the doc:
Note: When using NavigationUI, the top app bar helpers automatically transition between the drawer icon and the Up icon as the current destination changes. You don't need to use
ActionBarDrawerToggle.
In your code remove the code about the ActionBarDrawerToggle and use:
AppBarConfiguration appBarConfiguration =
new AppBarConfiguration.Builder(...........)
.setDrawerLayout(drawerLayout)
.build();
