java - float 操作按钮菜单不随标题滚动

Question

我目前正在编写一个小应用程序，并尝试集成 Google 的“ Material 设计”。

我在我的应用程序中使用 github 的 float 操作菜单按钮库，我有一些担心。

与单个按钮不同，菜单生成更大的 View 。我把菜单放在 fab 标题下。但代码看起来不太好。

我希望在我的标题下正确调出菜单工厂(我使用 CollapsingToolbarLayout)。菜单跟随滚动。但我被困在这里了。

我的问题是如何将菜单 fab 放在标题和卡片 View 之间，以及如何使用折叠工具栏滚动 fab 菜单。

提前谢谢您。

我的布局:

Answer 1

将layout_anchor更改为“appbarlayout”而不是“image”
