Question

我有一个scrollview作为片段的根布局，在该scrollview中有一个linearlayout，其内部有一个constraintlayout和一个recyclerview，并且在recyclerview中有两列。当我的片段启动时，UI很好，但是当我单击一个按钮时，一列会跳向屏幕的右侧。我没有在左边或右边添加任何marginlayout，所以我不知道为什么会这样。以前没有这个问题，在使用scrollview之后我遇到了这个问题。我已经粘贴了下面的代码。关于单击按钮后列为何更改的任何想法。

就我而言，这是线性布局的问题，因为在我使用线性布局之前就可以了。

片段xml：

Answer 1

尝试将android：clickable =“ true”这行添加到ScrollView

android:clickable="true"

尝试使用Recyclerview并设置GridLayoutManger并以这种方式定义列。

        recyclerview.setLayoutManager(new GridLayoutManager(this,2,LinearLayoutManager.VERTICAL,false));

单击按钮后，Recyclerview适配器中的项目跳到右侧
