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"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/background_light"
    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/main_appbar"
        android:layout_width="match_parent"
        android:layout_height="400dp"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/main_collapsing"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleTextAppearance="@android:color/transparent"
            app:layout_scrollFlags="scroll|exitUntilCollapsed"
            app:title="">

            <fragment xmlns:tools="http://schemas.android.com/tools"
                android:id="@+id/map"
                android:name="com.google.android.gms.maps.SupportMapFragment"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                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"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

        </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>

我有布局CoordinatorLayout作为rootview,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平滑滚动是错误和谷歌仍然没有解决它.:|

删除NestedScrollView.RecyclerView用app:layout_behavior="@string/appbar_scrolling_view_behavior"那就足够了.

你可以使用第三方库:smooth-app-bar-layout
