我的应用程序中有一个 ScrollView，在其中我创建了一个线性布局，其中包含各种元素，但问题是我底部的按钮未正确显示。它们在底部被切断。我已经使用了填充和边距，但什么也没有发生。下面是我的布局

有人可以告诉我我错过了什么吗？
最佳答案
在 ScrollView 下包裹另一个 LinearLayout 并给出
paddingBottom 到第二个子级(第二个 LinearLayout)
所以将其添加到添加的线性布局中:-
android:paddingBottom="20dp"
填充的正确顺序:-
ScrollView
||
LinearLayout X- X -- > padding Bottom wont be applied
||
LinearLayout with paddingBottom -- > is applicable
注意:- paddingBottom 和 marginBottom 不能应用于 ScrollView 的直接子级.
