Answer 1

您可以通过阅读The Android 3.0 Fragments API博客得到您的详细解答。一个相关的观点是：

Embedded Activities via ActivityGroup were a nice idea, but have always been difficult to deal with since Activity is designed to be an independent self-contained component instead of closely interacting with other activities. The Fragment API is a much better solution for this, and should be considered as a replacement for embedded activities.
