Java Android studio约束调整大小问题

我是Android Studio的新手，我面临着一个关于ConstraintLayout的问题。也就是说，我试图让我的应用程序完全响应，虽然我的组件的宽度可以完美地调整到任何屏幕大小，但我不知道如何使高度以同样的方式调整。相反，我的布局垂直离开屏幕

我希望布局完全适合任何屏幕大小。

我认为您的约束与xml文件中的视图没有正确连接

试试这个，我已经修改了你的xml代码。看看这个，让我知道

愉快的编码。

考虑使用包含ConstraintLayout元素的ScrollView元素，我建议使用单个ConstraintLayout，至少这是必要的。当我第一次开始使用ConstraintLayout时，它非常有用。

这里有一个类似的问题，这正是我想要的。非常感谢。如果@MateuszSkorupiński真的对你有帮助，我很乐意帮助你。请让我的答案正确。谢谢
