推荐答案

从GoogleIO ListView控件的开发人员之一的答案是：不要把一个ListView的滚动型。这意味着如果你想为你正在尝试做的，你也许并不需要一个ListView在所有未滚动一个ListView。

A answer from one of the ListView Developers from the GoogleIO is: Never put a ListView in a ScrollView. This means if you want a ListView that is not scrolling as you are trying to do you maybe don't need a listview at all.

您可以创建一个ListView放的LinearLayout中，并使用适配器从两个列表视图，通过手动添加列表中的项目<一个href=\"http://developer.android.com/reference/android/view/ViewGroup.html#addView%28android.view.View%29\"相对=nofollow> linearlayout.addView 现在你有一个包含列表的所有项目之一滚动视图。因为没有回收和项目的仅加载列表中，这是非常低效的，只有可用的，如果你没有那么多的项目。

You could create a ListView put a Linearlayout in it and use the Adapters from the two Listviews to manually add the items of the list via linearlayout.addView Now you have one scrollable view that contains all items of the list. Because there is no recycling and only loading of the items in the list this is very inefficient and only usable if you don't have that much items.

，你可以去，如果你有第二个更复杂的方式说，在每个列表20个项目是使用自定义的适配器，需要两个listadapters，让你把所有的项目在一个列表。

The second more complicated way that you can go if you have say 20 items in each list is to use a custom adapter that takes the two listadapters and let you put all the items in one list.
