I am using a ViewPager
to display fragments inside a FragmentActivity
. ViewPager gets fragments from the attached FragmentPagerAdapter
.
mViewPager = (ViewPager) findViewById(R.id.view_pager);
mAdapter = new HomePagerAdapter(getSupportFragmentManager());
mViewPager.setAdapter(mAdapter);
Suppose ViewPager
has 3 fragments to display: Fragment1
, Fragment2
, Fragment3
. Fragment1
is a grid fragment and displays a grid. Fragment2
and Fragment3
have their own content to display. When the use swipes on the screen, ViewPager
will display the next fragment - Fragment2
. And so on.
What I want is that, when an item from the grid (displayed by Fragment1
) is clicked, Fragment1
should be completely replaced with some other fragment, say Fragment4
(this is different fragment and is not returned by the attached adapter). User will work on Fragment4
and after ButtonBack
click (just button iside Fragment4
), Fragment1
with the grid should be displayed again. Meanwhile ViewPager
should behave the same ie on swipe, the next fragment (in our case Fragment2
) will be displayed.
So I just want to get the same behavior as in example: http://developer.android.com/training/basics/fragments/fragment-ui.html#Replace
So, is this possible to achieve? If yes, then how to? I would greatly appreciate for your help. Alex. PS Sorry for my English:)
I've made a little example that shows how to achieve it:

I think the point is to use another fragment as a container.
You will have to do the fragment transaction and add the existing fragment into backstack. I created a sample project to show you how to do it.
The code is not fine tuned, I just created it to show you how to do it.

But please be aware that even if you press back at any of the view pager screen, the previous fragment ends up showing as it is the same activity.
IF this is not expected behavior, then you should consider having multiple activities instead ( like tab layout )
One way to achieve this is by adding another FragmentActivity
that displays your Fragment4
. Use Intent
to start this activity and sent grid item position or other data in Extra
.
On press of backbutton this activity will be finished and last activity with view pager will be displayed.
