i had add add 3 tab Now the problem is that when i set some data in tab1 view and move to tab2 the reselect tab1 the data on tab1 is as it is but when i move to tab3 to tab1 then tab1 data is clear. so cany anyof you have idea to solve this?

At the moment your code appears to be partly action bar tabs and partly ordinary fragments.

If you are trying to use action bar tabs then you need a tab listener. In onTabSelected you should add/replace and in onTabUnselected you should remove.

Please see http://developer.android.com/guide/topics/ui/actionbar.html section "adding navigation tabs" for a good example.
