Do not connect toolbar to navigation drawer how to do it?

I use the MaterialDrawer library but for some unknown reason the Drawer itself works and the toolbar doesn't.

I have a class from which activity is extends and it contains this method:

public void  Drawer(Toolbar toolbar, Context context, android.app.Activity activity){
    setSupportActionBar(toolbar);

    DatabaseReference rootRef2 = FirebaseDatabase.getInstance().getReference();
    DatabaseReference uidRef2 = rootRef2.child("users").child(getUid());
    ValueEventListener valueEventListener2 = new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            String email = dataSnapshot.child("account").getValue(String.class);
            String Avatar = dataSnapshot.child("Avatar").getValue(String.class);
            Long coinsAmount = dataSnapshot.child("coinsAmount").getValue(Long.class);

            String coinsView = "Баланс: " + coinsAmount;




                if (Avatar.equals("1")) {
                    avatar = (R.drawable.a1);
                }
                if (Avatar.equals("2")) {
                    avatar = (R.drawable.a2);
                }


            IProfile profile = new ProfileDrawerItem()
                    .withName(email)
                    .withEmail(coinsView)
                    .withIcon(avatar);

            AccountHeader headerResult = new AccountHeaderBuilder()
                    .withActivity(activity)
                    .withHeaderBackground(R.color.grey_300)
                    .addProfiles(
                            profile
                    )
                    .build();


               result = new DrawerBuilder()
                    .withActivity(activity)
                    .withToolbar(toolbar)
                    .withAccountHeader(headerResult)
                    .addDrawerItems(
                            new PrimaryDrawerItem()
                                    .withName("Устройства")
                                    .withIcon(R.drawable.device)
                                    .withIdentifier(1)
                    )
                    .addDrawerItems(
                            new PrimaryDrawerItem()
                                    .withName("Сканер")
                                    .withIcon(R.drawable.scaner)
                                    .withIdentifier(2)
                    )
                    .addDrawerItems(
                            new PrimaryDrawerItem()
                                    .withName("Магазины")
                                    .withIcon(R.drawable.shop)
                                    .withIdentifier(3)
                    )
                    .addDrawerItems(
                            new PrimaryDrawerItem()
                                    .withName("Купоны")
                                    .withIcon(R.drawable.coupons)
                                    .withIdentifier(4)
                    )
                    .addDrawerItems(
                            new PrimaryDrawerItem()
                                    .withName("Архив Купонов")
                                    .withIcon(R.drawable.oldcoupons)
                                    .withIdentifier(5)
                    )
                    .withOnDrawerItemClickListener((view, i, iDrawerItem) -> {
                        if(iDrawerItem.getIdentifier() == 1 && !Activity.equals("Menu")){
                            Intent intent = new Intent(context,MenuActivity.class);
                            startActivity(intent);
                        }
                        else if(iDrawerItem.getIdentifier() == 2 && !Activity.equals("Scaner")){
                            Intent intent = new Intent(context,DecoderActivity.class);
                            startActivity(intent);
                        }
                        else if(iDrawerItem.getIdentifier() == 3 && !Activity.equals("Shop")){
                            Intent intent = new Intent(context,ShopActivity.class);
                            startActivity(intent);
                        }
                        else if(iDrawerItem.getIdentifier() == 4 && !Activity.equals("oldCoupons")){
                            Intent intent = new Intent(context,oldCouponsActivity.class);
                            startActivity(intent);
                        }

                        return false;
                    })
                    .build();

            getSupportActionBar().setDisplayHomeAsUpEnabled(true);
            getSupportActionBar().setHomeButtonEnabled(false);

        }

        @Override
        public void onCancelled(@NonNull DatabaseError databaseError) {

        }

    };
    uidRef2.addValueEventListener(valueEventListener2);




}

So I connect the drawer

Drawer(toolbar,LibraryActivity.this,LibraryActivity.this);

XML this Activity:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout            xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>


<include
    android:id="@+id/mytoolbar"
    layout="@layout/toolbar" />
<include layout="@layout/content_menu" />

</androidx.constraintlayout.widget.ConstraintLayout>

Another important detail, if you place setSupportActionBar in OnCreate Activity together with the launch of activity toolbar is loaded on the second and immediately disappears

Here's how it looks in practice

Toolbar.xml

<androidx.appcompat.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:iosched="http://schemas.android.com/apk/res-auto"


android:id="@+id/toolbar_actionbar"
android:layout_width="match_parent"
android:layout_height="@dimen/materialize_toolbar"
android:background="@color/grey_500"
android:minHeight="?attr/actionBarSize"
android:theme="?attr/actionBarTheme" />

Map.xml

<?xml version="1.0" encoding="utf-8"?>
 <fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.Activities.MenuActivity"
/>

Try build your layout like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

        <LinearLayout
            android:id="@+id/container_toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">
            <!-- Include your Toolbar -->
            <include
                android:id="@+id/mytoolbar"
                layout="@layout/toolbar" />
        </LinearLayout>

        <FrameLayout
            android:id="@+id/container_body"
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_weight="1">
            <!-- Embed your fragment in a Layout View-->
            <fragment xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:map="http://schemas.android.com/apk/res-auto"
                xmlns:tools="http://schemas.android.com/tools"
                android:id="@+id/map"
                android:name="com.google.android.gms.maps.SupportMapFragment"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                tools:context="com.example.Activities.MenuActivity"
                />
        </FrameLayout>

</LinearLayout>

This layout can be optimized, but do a try with the example above. Basically we need to create two rows: a row to maintain the toolbar and a row to wrap the map view container.
