如何在右侧工具栏中添加切换按钮？

Question

我试图将切换按钮停在我的工具栏上。我无法将它们都集成在一起，因为使用SetSupportActionToolbar时出现错误。这是我的主要活动：

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tab_activity);
        SectionsPagerAdapter sectionsPagerAdapter = new SectionsPagerAdapter(this, getSupportFragmentManager());
        ViewPager viewPager = findViewById(R.id.view_pager);
        viewPager.setAdapter(sectionsPagerAdapter);
        TabLayout tabs = findViewById(R.id.tablayout);
        tabs.setupWithViewPager(viewPager);

        tablayout = (TabLayout) findViewById(R.id.tablayout);
//        appBarLayout = (AppBarLayout) findViewById(R.id.appbarid);
        viewPager = (ViewPager) findViewById(R.id.view_pager);
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.AddFragment(new PeopleTab(), "People");
        adapter.AddFragment(new EventsTab(), "Events");


        viewPager.setAdapter(adapter);
        tablayout.setupWithViewPager(viewPager);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
//        setSupportActionBar(toolbar);

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

这是活动的布局：

<android.support.design.widget.CoordinatorLayout 
    tools:context=".TabActivity">

    <android.support.v4.view.ViewPager
        android:id="@+id/view_pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
    <include
        layout="@layout/activity_navigation"/>

</android.support.design.widget.CoordinatorLayout>

这是我指定的activity_navigation：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">


    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:minHeight="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

        <android.support.design.widget.TabLayout
        android:id="@+id/tablayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
            android:layout_gravity="bottom"/>


        <android.support.design.widget.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="visible"
        android:text="@string/people" />

        <android.support.design.widget.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="visible"
        android:text="@string/ev" />

        <FrameLayout
            android:id="@+id/content_frame"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>

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

我想要这样的输出：
