如何将"微调器"放在按钮顶部

Question

有没有办法让我的微调器放在按钮上？(我的按钮顶部会有各种各样的东西，当你按下按钮时，上面的所有东西，包括按钮，都会消失((按钮横跨屏幕的宽度(现在它是我按钮下的微调器。我试着查看不同的RelativeLayout设置，但没有成功。这是下面的xml代码

编辑：我把我的按钮和微调器放在一个框架布局中，当我在手机上测试它时，它就可以工作了。然而，我在一部更大尺寸的手机(和一个更新的安卓版本(上测试了它，但旋转器没有显示(可能又隐藏了

Answer 1

尝试调用

findViewById(R.id.spinner).bringToFront();

Answer 3

我想我设法解决了一些问题——我创建了一个"FrameLayout"，并将我的微调器&按钮。

应该做这项工作，除非我发现问题，我会回到这里，否则这个问题应该得到解决。：(谢谢

如果有人想知道：

我把我的"按钮"放在FrameLayout中，然后把我想要的元素放在上面，放在下面(就像下面的代码一样(，就像这样：
