Android更新真快——Fragment 代替 TabActivity

ActivityGroup

This class was deprecated in API level 13.
Use the new Fragment and FragmentManager APIs instead; these are also available on older platforms through the Android compatibility package.

TabActivity

This class was deprecated in API level 13.
New applications should use Fragments instead of this class; to continue to run on older devices, you can use the v4 support library which provides a version of the Fragment API that is compatible down to DONUT.
