Question

我正在创建一个自定义对话框，其中包含大量元素的ScrollView。

问题是ScrollView将所有内容移动到顶部。好像它增加了保证金底部。因此，当ScrollView滑动到底部时，顶级内容被裁剪并且机器人内容具有太多可用空间。请看截图。

1）当滑到顶部时，裁剪内容。

2）当滑到底部时，内容有余量

它应该是这样的：

代码： dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/root"
android:layout_width="match_parent"

<View

    </LinearLayout>
</ScrollView>
</RelativeLayout>

为什么ScrollView有这种行为的想法？

Custom DIalog中的ScrollView会在底部添加边距
