I have an activity with a fragment container layout and in that layout i load a fragment A which has a listview (listview loads data from web). Now on clicking listview item i want to show detail view. For that i am loading another fragment B which is detail fragment. Now to do that first i used
FragmentTransaction ft = ((FragmentActivity) context).getSupportFragmentManager().beginTransaction();
ft.replace(R.id.fragmentsContainerLayout, new ScheduleDetailsFragment());
ft.addToBackStack(null);
ft.commit();
But using replace remove the previous fragment A which contain listview and on pressing back it again reloads the onCreateView method of fragment A and its listview data. I want to prevent it from loading fragment A again (or sending call to webserver) on backpress. I want to maintain fragment A state and its listviews scroll position. To do that i used second option which is
FragmentTransaction ft = ((FragmentActivity) context).getSupportFragmentManager().beginTransaction();
ft.add(R.id.fragmentsContainerLayout, new ScheduleDetailsFragment());
ft.addToBackStack(null);
ft.commit();
If i use add() then Fragment B loads on top of Fragment A and Fragment A still visible. It shows both fragments overlapping each other and transparent. I also came across anothe solution which is to use show() and hide() methods. But i dont think that is an efficient way to achieve that. Can anyone suggest an effective solution?

I have 2 fragments the first contains a button which on clicked opens a fragment with a ListView in it. I have a shared element transition for the button to transition into the new fragment (root layout) but I would also like to have this transition in reverse (the list fragment contracts into the button again).
However currently I detect the list item click and send an event to the Activity which pops the listview fragment off the backstack (popBackStackImmediate()) hence does not show the transition.
Is there a good way to allow back navigation while preserving reverse transition to work as well?
did you try this:
FragmentManager fm = getSupportFragmentManager();
fm.popBackStack();
fm.executePendingTransactions();
PS: use getSupportFragmentManager() if you're using the support library else use getFragmentManager().
I need to replace one list fragment with another one (also list). But they overlaps.
Fragments were added dynamically:
fragmentManager.beginTransaction().replace(R.id.container,
CatalogFragment.newInstance(position + 1)).addToBackStack(null).commit();
and I'm trying to replace this CatalogFragment with LessonFragment in OnFragmentInteractionListener when the item of CatalogFragment's list item clicked like this:
// fragmentManager = getSupportFragmentManager();
// fragmentManager.popBackStack();
FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.fragment_catalog, LessonsFragment.newInstance());
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
I've been trying to pop previous item in backStack. Also tried to give the name of backStack of CatalogFragment and then remove it manually. Doesn't work.
Both of fragments are getting displayed at the same time.
I have tried first 10 solutions of google and tried to use standard developer.android's solution of replacement. Fail.
Please help if you know how. Thanks in advance.
P.S. Tell if some more code needed.
From your code, you added CatalogFragment in a layout: R.id.container, but you replace your LessonsFragment in another layout: R.id.fragment_catalog. I think that it's the reason why 2 fragments display at the same time. You should only use 1 Layout view to display fragments with you want only 1 visible.
When I do transaction.setCustomAnimations(R.anim.move_left_in, R.anim.move_left_out), instead of sliding the fragment out: the window first remove the view child views and then slide. This makes for a poor user experience. What I want is for the view and all its children intact to simply slide out. I am using the same transition for activities and it works fines; no funny attenuation before sliding. How might I get the fragment transition to behave more like the activity transition?
MyFragment fragment = new MyFragment();
fragment.setArguments(bundle);
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.setCustomAnimations(R.anim.move_left_in, R.anim.move_left_out);
transaction.replace(R.id.holder, fragment, MyFragment.class.getSimpleName());
transaction.addToBackStack(null);
transaction.commit();
I have a FragmentActivity that contains a FrameLayout. I use the following code to add Fragments to the Fragment Activity.
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.add(R.id.fragment_content, fragment, fargmentTag);
ft.addToBackStack(null);
ft.commit();
Now R.id.fragment_content is FrameLayout. This adds a Fragment onto the view. But the underlying view still remains visible. Meaning the one lying view is seen through the new fragment ? What am i doing wrong.
Kind Regards
for the next fragment use ft.replace(); so the previous one will be repalced.
Either ft.remove() the old fragment, or use ft.replace() instead of ft.add().
ft.replace() should work fine, otherwise you have to update your question for a better understanding.
Using ft.replace will replace any previously added fragment with this fragment but if the activity has some view added to its layout rather than a fragment ,then the fragment added through add or replace will show its content over it rather than replacing it as it is not a fragment.
either add another layout within your main layout and assign it some id and then add the fragment to that container.
Hope it helps.
I have developed an android application by extending to FragmentActivity. Everything works exactly as it done. I have put NAVIGATION_MODES as TABS. I have a LISTVIEW inside TAB A of FRAGMENT A. When the user clicks on LISTVIEW ITEM, new Fragment/ACTIVITY should launch showing the same ACTION BAR and same TABS. How can I achieve this.
Please suggest any methods.
Thanks
Get the container of the current Fragment A with the ListView and replace the Fragment inside
so in the onclick method of the listview adapter:
FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(FragmentA.this.getParent().getID(), mNewFragment);
ft.addToBackStack(null);
ft.commit();
since FragmentA.this.getParent().getID() is very clunky, search for the ID of the Container where FragmentA is located in, and use it instead. R.id.FragmentAContainerID
