I am experiencing a weird issue. I created a navigation view inside a drawer layout, however navigation view is just visible once the activity starts. The toolbar hamburger menu is not clickable.
main_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:showIn="navigation_view"
    >
    <group android:checkableBehavior="single">
    <item android:id="@+id/menu_explore" android:title="@string/explore"
        android:icon="@drawable/exploreicon" />
    <item android:id="@+id/menu_profile" android:title="@string/profile"
        android:icon="@drawable/profileicon"/>
    <item android:id="@+id/menu_search" android:title="@string/search"
        android:icon="@drawable/searchicon"/>
    <item android:id="@+id/menu_settings" android:title="@string/settings"
        android:icon="@drawable/settingsicon"/>
    <item android:id="@+id/menu_bookmarked" android:title="@string/bookmarked"
        android:icon="@drawable/bookmarkicon"/>
    <item android:id="@+id/menu_logout" android:title="@string/log_out"
        android:icon="@drawable/logouticon"/>
    </group>
</menu>

        <item name="windowNoTitle">true</item>
        <item name="android:windowFullscreen">true</item>
    </style>
Main Activity:
public class MainActivity extends AppCompatActivity {
    private DrawerLayout drawerLayout;
    private ActionBarDrawerToggle actionBarDrawerToggle;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = findViewById(R.id.mainToolbar);
        toolbar.setTitle(R.string.app_name);
        setSupportActionBar(toolbar);
        drawerLayout = findViewById(R.id.drawerLayout);
        actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,
                R.string.open,R.string.close);
        drawerLayout.addDrawerListener(actionBarDrawerToggle);
        actionBarDrawerToggle.syncState();
    }
}
I want the navigation view to be only visible when the hamburger icon in the toolbar is clicked. Every tutorial I followed did the same things with me, however mine doesn't show inside the toolbar.
