    </LinearLayout>

</ScrollView>

我使用了fillViewport并且还使基础内容包装。请帮忙。

Answer 1

Per 'How can I put a ListView in a ScrollView'? question以及随后的回答，ListView处理他们自己的内部滚动，它既昂贵（从布局性能的角度来看），也不能将一个滚动容器放在另一个滚动容器中。

解决此问题的最简单方法是使用ListView.addHeaderView和ListView.addFooterView，如果您希望布局中的其他项目与ListView一起滚动。

Answer 2

永远不要将ListView放在ScrollView中！ Google提供了“Scrollview中的android ListView”以获取更多信息。一个例子就是这个：How can I put a ListView into a ScrollView without it collapsing?

ScrollView无法使用LinearLayout
