我有NestedScrollView一些文本，因为那是在 CoordinatorLayout，当我将它滚动到末尾时NestedScrollView不会显示过度滚动效果，我的猜测是当我到达末尾并尝试滚动更多时，我不会滚动 nestedScrollView 但我滚动CoordinatorLayout。

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/activity_news_main_content"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/activity_news_appbar"
        android:layout_width="match_parent"
        android:layout_height="@dimen/activity_news_background_height"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/activity_news_collapsing_toolbar"

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

那个设计是错误的。

看：

<include
    android:id="@+id/app_bar"
    layout="@layout/news_app_bar"/>

您将布局包含在CollapsingToolbarLayoutwhich 应该在NestedScrollView而不是 that 中CollapsingToolbarLayout。

像这样做你的东西NestedScrollView：

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/activity_news_main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clipToPadding="false"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <!--Here is the contents-->

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

            <TextView
                android:id="@+id/activity_news_subtitle"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />

            <TextView
                android:id="@+id/activity_news_description"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />
        </LinearLayout>-->

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

    <android.support.design.widget.AppBarLayout
        android:id="@+id/activity_news_appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbarmain"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@color/colorPrimary"
            app:layout_collapseMode="pin"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/activity_news_collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="top"
            app:contentScrim="@color/colorPrimary"
            app:layout_collapseMode="pin"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <ImageView
                android:id="@+id/activity_news_image"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:scaleType="centerCrop"
                app:layout_collapseMode="parallax"
                app:layout_collapseParallaxMultiplier="0.7"
                app:layout_scrollFlags="scroll|exitUntilCollapsed" />


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


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

并阅读：CollapsingToolbarLayout

CollapsingToolbarLayout 是 Toolbar 的一个包装器，它实现了一个折叠的应用栏。
