为什么我的布局在没有滚动视图的情况下自动滚动? [英] Why does my layout auto scroll without a scroll view?

问题描述

我在实现工具栏时遇到了一些麻烦，但是它从来没有停留在一个地方.这是由于布局中带有recyclerView的一些自动滚动的东西，我很奇怪，因为没有scrollView.

I have been having some trouble implementing a toolbar but it never stays in one place. This is due to some auto scroll thing with recyclerView in the layout, which I weird since there is no scrollView.

如何解决此问题，以便在滚动时工具栏处于固定位置?

How do I fix this so the tool bar is in a fixed position when I scroll?

这是我的代码，因此您可以告诉我修复该代码所需要做的事情.

Here is my code so you can tell me what I need to do in order to fix it.
