工具栏未滚动

Question

将NestedScrollView应用于活动后，工具栏不会与内容一起滚动。我尝试了很多滚动选项和标志。高度和宽度参数不在此处写入。

    <android.support.design.widget.AppBarLayout
        android:fitsSystemWindows="true"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.design.widget.CollapsingToolbarLayout

            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|enterAlwaysCollapsed"
            app:collapsedTitleGravity="fill_vertical">

            <android.support.v7.widget.Toolbar
                app:layout_collapseMode="pin"
                app:popupTheme="@style/AppTheme.PopupOverlay"
                android:overScrollMode="always"/>

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

     <android.support.v4.widget.NestedScrollView
        android:fillViewport="true"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        tools:context="a.fruitsbook.ScrollingActivity"
        tools:showIn="@layout/activity_scrolling"
        android:overScrollMode="always">

           <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerViewScroll"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

        </android.support.v7.widget.RecyclerView>

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

Answer 1

删除NestedScrollView和

在recyclerView中添加app：layout_behavior =“@ string / appbar_scrolling_view_behavior”。
