Android Studio - Sliding Tabs appear below action bar instead of on action bar -

i've created set of sliding tabs view pager set activity_main.xml. in project tabs show below action bar if divided.

i'd have them part of action bar.

what should edit in code accomplish this?

i've scoured web reply can turn nil works particular project.

to reply own question, take few steps accomplish this. first need create own custom action bar in seperate xml file. need apply "noactionbar" theme activity want set action bar silding tabs in. need write in java want set action bar in particular activity own custom action bar. believe, don't quote me, need add together sliding tabs in action bar layout file along view pager.

obviously there lot of steps , hard explain them in way. slidenerd has superb set of video tutorials on how in case you're visual learner.
