Separate Back Navigation for a Tabbed View Pager in Android

Question

What I want.

In a tab sliding menu context, I want to replace a fragment to another inside a tab, and maintaining the tab menu, and also the current tab

Answer 1

You can change fragments inside page fragment. For example, TAB_A implements logic of picking fragment 1 or 2, and displaying picked fragment inside. Hierarchy looks like:

ViewPager -> TAB_A -> fragment 1 or 2 (displaying inside TAB_A).

Also you should use getChildFragmentManager() to manage fragments inside TAB_A.
