android - AppBarLayout 与 FrameLayout 容器作为滚动内容不起作用

Question

我正在尝试使用最新的设计库使我的工具栏在滚动时隐藏/显示。我的问题是我拥有的滚动内容在 fragment 中，我只是将它注入(inject) FrameLayout 容器并且它不起作用。这是我的 Activity :

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

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <include layout="@layout/layout_toolbar" />

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

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

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

<FrameLayout
    android:id="@+id/navigation_drawer_container"
    android:layout_width="@dimen/navigation_drawer_width"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    tools:layout="@layout/fragment_nav_drawer_anon" />

还有我的 fragment :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/pull_to_refresh"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</android.support.v4.widget.SwipeRefreshLayout>

<TextView
    android:id="@android:id/empty"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textSize="18sp"
    android:fontFamily="sans-serif"
    android:color="@color/dark_grey"
    android:padding="60dp"/>

和工具栏:

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
style="@style/Widget.MyApp.ActionBar" />

我关注官方doc这个demo ，但仍然无法弄清楚如何使其工作。

用 android.support.v4.widget.NestedScrollView

替换您的 FrameLayout

NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.
