Cуть в том что есть Drawer в нем 6 Items при открытии приложения мы сразу стоим на первом Item и когда переходим по его Tab то текст меняется. Но когда открываю 2ой Item то текст остается тот же что и в первом Tab, то есть он не меняется вообще. Побывал в activity_main.xml подключать 2 ViewPager-a тогда тексты налажуются на друг друга.
Это код activity_main.xml
