Android tab Effect

Http://www.javaeye.com/topic/465371

To create a tabhost in Main. xml or a custom *. xml file, two elements tabwidget and framelayout are required to put the two elements in linearlayout. Framelayout is used to change the content.

Note: tabwidget and framelayout have different ID namespaces: Android: Id = "@ Android: ID/idnames". This is required, so tabhost can be automatically found. The activity must inherit tabactivity.

Tabhost control-> tabwidget (must be named tabs)-> framelayout (must be named tabcontent ).
