问题描述
我正在尝试创建一个带有标题的布局，在其下方有一个横幅，然后在该横幅下有几个ListView.我希望除标题外的整个屏幕都可滚动.现在我知道ListView不会在ScrollView中滚动，因此我将ListView的高度设置得足够大以显示所有项目.问题是，即使进行了这些更改，我仍然可以看到ListView正在独立滚动，并且整个屏幕也无法滚动.
I am trying to create a layout with a header, a banner below it, and then a couple of ListView under the banner. I want the the complete screen to be scrollable except the header. Now I know that ListView does not scroll within a ScrollView so I have set the height of the ListView big enough to show all the items. The problem is that, even after these changes, I see that the ListView is scrolling independently and the complete screen is not scrollable.

推荐答案
将滚动视图的高度从match_parent更改为wrap_content.因为滚动视图仅在其总高度大于父视图的高度时才启用滚动.即替换
Change height of scroll view from match_parent to wrap_content. Because scroll view only enable scrolling if its total height is more than the height of parent view. i.e. replace
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
使用以下代码:
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true">
