Question

我试图将布局分为两部分，其中下部应该是可滚动的。但是滚动视图不会完全滚动直到结束。

我已经尝试过使用NestedScrollView。我也已经尝试在scrollview，约束布局，滚动视图中的最后一个视图中添加边距和填充。最后的按钮是不可访问的。视图突然在该按钮上方的textview中间结束。

    </android.support.constraint.ConstraintLayout>

   </ScrollView>

 </android.support.constraint.ConstraintLayout>

编辑：我将父约束布局更改为相对布局，现在它完全正常。仍然不知道为什么它之前没有。谢谢你的回复。
