Android 如何正确设置浮动动作按钮？

我有个问题。我用这个库来制作滑动面板。点击我添加了它，然后我试着在谷歌地图应用程序中制作浮动动作按钮（如图所示）。

但下面是我的结果。如何正确设置（使滑动面板传动装置顶部可能是）如图1所示

fragment_1.xml（查看滑动布局部分）

谢谢你的帮助

将

放在

之外，不要忘记使用marginTop和marginLeft定位它：

一个更简单的方法，就是我所做的，就是在滑动布局的第一项中添加28 dp的填充，并将滑动布局置于覆盖模式

Hello@ali nrd这不是我需要的。浮动操作按钮必须像谷歌地图应用程序中一样绑定到面板。你有什么想法吗？@NurzhanNogerbek没错，这也是我的问题。我也遇到了同样的问题。一旦我开始工作，我就会发布。但是你找到答案了吗？你好，伙计！是的，我解决了这个问题。您需要在库内部进行重大更改。检查它：
