            android:layout_marginBottom="@dimen/margin_floating_action_menu"
            android:layout_marginRight="@dimen/margin_16"
            android:gravity="right"
            android:orientation="vertical">

        </LinearLayout>

    </RelativeLayout>

    <ImageView
        android:id="@+id/fab_home"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|right"
        android:layout_margin="@dimen/margin_16"
        android:src="@drawable/floating_btn_menu" />

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

但它不起作用。 ToolBar不会与RecyclerView的滚动事件折叠。

任何人都可以帮我吗？

Answer 1

只需从 app：layout_scrollFlags 中删除 exitUntilCollapsed ，然后CollapsingToolBar就会开始工作。

PS：经过测试

android：collapsingtoolbar不工作
