Android 如何获取constraintView以填充scrollView内的宽度空间？

我在scrollView中有一个constraintLayout，如下图所示，constraintLayout在宽度方面不会填充屏幕。我怎样才能让它这样做

</androidx.constraintlayout.widget.ConstraintLayout>


 </ScrollView>

如果您希望完全像下面这样


那么请检查这个xml

上面的代码看起来非常好，请提供一个屏幕截图，让我们更好地理解。给你（对不起，我对新的constraintView不太熟悉，所以我认为这是一个明显的错误）ConstraintLayout儿童并不真的需要重力。你可以用约束做任何事情。上面的代码看起来非常好。请提供一个屏幕截图，让我们更好地理解。给你（很抱歉，我不太熟悉新的constraintView，所以我认为这是一个明显的错误）ConstraintLayout儿童并不真的需要重力。你可以用约束做任何事情。
