Question

Does anybody know what is the name of upper part of this image(Buddies,activity,chat,history) which is like tab and also how to implement it in android tablet?

Answer 1

This is tabs. Before honeycombs tabs were done using the TabActivity + Activity group. But now the activity group class is deprecated and fragments should be used instead.

Answer 2

That is the TabHost: http://developer.android.com/reference/android/widget/TabHost.html
