如何在协调器布局内使用嵌套滚动视图进行平滑滚动

Question

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

            app:title="">

            <fragment xmlns:tools="http://schemas.android.com/tools"

                tools:context="com.mydermacy.www.beyou.activities.CompareClinicsActivity" />

            <android.support.v7.widget.Toolbar
                android:id="@+id/main_toolbar_clinics"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"

        </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"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">


    <android.support.v7.widget.RecyclerView
            android:id="@+id/rc_clinic_compare"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:behavior_overlapTop="184dp"
            android:background="@color/background" />

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

    <!--app:layout_behavior="@string/appbar_scrolling_view_behavior" />-->

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

我有CoordinatorLayout作为rootview的布局，在里面我有两个子视图AppBarLayout和NestedScrollView。我无法进行平滑滚动。可以做些什么来实现平滑滚动？

Answer 1

CoordinatorLayout和CollapsingToolbarLayout平滑滚动错误，Google仍然没有修复它。 ：|

删除NestedScrollView。 RecyclerView app:layout_behavior="@string/appbar_scrolling_view_behavior" main/ include/folder1 include/foo/ Test/ foo/ include/... Test/... 已足够并且可以修复。

您可以使用第三方库：smooth-app-bar-layout

<RelativeLayout

</RelativeLayout>
</ScrollView>

我删除了嵌套滚动视图和app：behavior_overlapTop =＆＃34; 184dp＆＃34;从循环视图，所以问题得到解决，我添加了app：layout_behavior =＆＃34; @ string / appbar_scrolling_view_behavior＆＃34;回收视图感谢您的帮助
