Answer 1

Just Put your NavigationView bottom of all layout inside DrawerLayout 

Like this 

<android.support.v4.widget.DrawerLayout
        xmlns:android="https://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:openDrawer="start">

     ---- Here is your layouts

    <android.support.design.widget.NavigationView
            android:id="@+id/nav_view"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            app:headerLayout="@layout/nav_header_main"
            app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>

Answer 2

尝试手动添加逻辑：

toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
    drawerLayout.openDrawer(GravityCompat.START);
}
});

请将RelativeLayout替换为DrawerLayout的父布局

 <androidx.drawerlayout.widget.DrawerLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/white"
        android:fitsSystemWindows="true"
        tools:openDrawer="start">

        <include
            layout="@layout/app_bar_home_navigation"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <com.google.android.material.navigation.NavigationView
            android:id="@+id/nav_view"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:fitsSystemWindows="true"/>
    ..

    ..
    </androidx.drawerlayout.widget.DrawerLayout>

在MainActivity中

DrawerLayout drawer;
    ActionBarDrawerToggle toggle;
 drawer = findViewById(R.id.drawer_layout);
 toggle = new ActionBarDrawerToggle(
                this, drawer, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.addDrawerListener(toggle);
        toggle.syncState();

并在菜单按钮上单击添加此功能以打开和关闭

 if (drawer.isDrawerOpen(GravityCompat.START)) {
                        drawer.closeDrawer(GravityCompat.START);
                    } else {
                        drawer.openDrawer(GravityCompat.START);
                    }

无法滑动导航抽屉
