将ViewPager和选项卡放在一个片段中并替换它

Question

In my main activity I have a ViewPager with two tabs and each of them has its contents in a fragment. One of the tabs holds a list of items and when I press on an item from that list I want the details of that item to appear on the screen. I thought of putting the whole ViewPager in a fragment and when the user taps the item the fragment representing the whole ViewPager is replaced with another fragment representing the details of the item. Is it possible and is it a good practice? Maybe I should just start another activity with the details of the item?

How you do it is your own choice. It's perfectly fine to switch your Fragments.

getSupportFragmentManager().beginTransaction().replace(android.R.id.content, new FragDetails())
                    .addToBackStack(FragPager.class.getName()).commit();

Switching to another Activity is fine too, you just have more of a "flicking" screen when opening a new Activity (and some other life cycle stuff too of course). If you don't want that, switch Fragments.
