问题描述

我是一个新到Android的东西。我创建包含将获得动态填充列表视图的应用程序。我的要求是，当该列表是空的，我想显示的消息。我不想只是为了显示此消息创建其他的视图。有没有什么好的办法做到这一点？有什么建议？

I am a new to Android stuff. I am creating an application that contains a list view that will get dynamically populated. My requirement is when the list is empty, I would like to show a message. I don't want to create additional views just for displaying this message. Is there any nice way to do this? Any suggestions?

推荐答案

ListActivity 有一个功能，它显示了一个特定视图时，列表是空的： @android：ID /空。您可以轻松地只使用一个自定义布局与 ListActivity 来实现这一目标。

ListActivity has a feature where it shows a specific view when the list is empty: @android:id/empty. You can easily just use a custom layout with ListActivity to achieve this.

如果你不想使用 ListActivity 你总是可以看看<一实施href=\"http://www.google.com/$c$csearch/p?hl=en#uX1GffpyOZk/core/java/android/app/ListActivity.java&q=listactivity.java&sa=N&cd=1&ct=rc\">ListView.java并适应这一点。

If you don't want to use ListActivity you can always look at the implementation of ListView.java and adapt that.
