Question

因此，我不想使用FAB，而是将Styled文本视图设置为与将fab放入锚点时的结果相同。问题是它不起作用，滚动时，文本视图的一半仍然可见，甚至隐藏了强大的折叠工具栏。

如何使用文本视图而不是FAB实现此类行为？

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

     <TextView
        android:id="@+id/details_price"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:background="@drawable/drawable_details_price_background"
        android:padding="@dimen/layout_padding"
        android:textColor="@color/textColorPrimary"
        app:layout_anchor="@id/app_bar_layout"
