我在某处读到谷歌称之为“功能区菜单”。
无论如何,这就是我的意思(也看看这个博客):
这是 Google+ 应用程序。当你点击 ActionBar 上的 G+ 图标时,整个屏幕向右移动并出现一个菜单。请注意,ActionBar 也会移动。
我想在我的应用程序中执行此操作,但我不知道如何操作。我对动画框架有基本的了解。
问题是:
- 我必须使用什么样的布局?
- 如何为整个屏幕设置动画(使用 ActionBar)?
我希望这些不是太笼统的问题。我在问例子。先感谢您。
好,我知道了。这很简单。
getWindow().getDecorView();
此行为您提供活动的主视图。主视图包含活动中显示的所有内容。然后你可以动画它。答案很简单。
这个链接对我帮助很大:http ://android.cyrilmottier.com/?p=658
这不是继续的方法。就像 Cyril Mottier 所说的那样,这是一个 hack,我发现了很多问题。我重做了一切,现在我正在实现自己的 ActionBar。
我也在寻找这个。同一事物的另一个名称是滑出导航。以下是我在 Github 上找到的解决方案:

您可以通过导航抽屉很好地做到这一点,这是我找到的示例
