NestedScrollViewLayout内的SwipeRefreshLayout内的RecyclerView无法滚动

Question

我有一个折叠工具栏和嵌套滚动视图的活动FrameLayout,我将片段放在其中.最初,我FragmentA用CardView放入它.

效果很好.当我单击一个按钮时,我将其替换FragmentB为另一个包含RecyclerView的按钮.

当我添加FragmentBI cant滚动到列表的底部.

    android:layout_width="match_parent"
    android:layout_height="340dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:fitsSystemWindows="true">


    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_scrollFlags="scroll|exitUntilCollapsed|enterAlwaysCollapsed"

        app:contentScrim="?attr/colorPrimary"
        app:expandedTitleMarginStart="48dp"
        app:expandedTitleMarginEnd="64dp">

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

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="fill_vertical"
    android:fillViewport="true"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    >

    <!-- the layout which will be the content of the activity (which will be hosted inside the drawer (NOT the list of the drawer)) -->
    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        >

    </FrameLayout>

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

FragmentB布局:

<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/contentView"

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv_users"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        android:layout_width="match_parent"

        android:layout_height="wrap_content" />

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

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

    <!--</LinearLayout>-->

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

你把它RecyclerView放进去了NestedScrollView.
我认为更好的解决方案是拥有NestedScrollView或RecyclerView不是两者,因为RecyclerView已经在实施NestedScrollingChild.

我的应用程序中有类似的布局.我做了同样的事情 - 将RecyclerView放到FrameLayout然后放在NestedScrollView中.停止正常工作.没有NestedScrollView一切正常.
