Question

So my app launch when it starts a FragmentActivity TestFActivity. That FragmentActivity contains a viewpager, which include 3 Fragments WelcomeFragment, ListFragment, and TagFragment.
Now, I want that when I click on an item from ListFragments, it opens a new FragmentActivity DetailsView, that will contains a viewpager (which include all of the items from the ListFragment and allow to swipe between them).

I have no clue on how to do that, and if this is the good logic to have with fragments.

Answer 1

Starting an Activity from within a Fragment is no different from starting one from another Activity, simply construct an Intent with the new Activity classname and call startActivity(). Something like:

//Fragments aren't a context, so used getActivity() instead
Intent intent = new Intent(getActivity(), DetailsView.class);
startActivity(intent);
