I have made an activity A which has a fragment X in it. In fragment X, EditText item has on click event which opens fragment Y. This fragment displays a list of names. I press a name in the list, fragment Y closes and sends the selected name of to fragment X EditText. Here's the code I wrote:
YFragment y = new YFragment();
y.setTargetFragment(x.class, code);
getActivity().getSupportFragmentManager()
.beginTransaction()
.replace(R.id.frame, y)
.addToBackStack(null)
.commit();
In fragment Y I have the code to send the data but the problem is in this block of code above. If I comment out the setTargetFragment line the code will work but no use as data will not be sent. If I run the app this error occurs:
java.lang.IllegalStateException: Fragment y{46d3d31 #3 id=0x7f090069} declared target fragment x{e2c16 #0 id=0x7f090104 android:switcher:2131296516:0} that does not belong to this FragmentManager!
To use setTargetFragment()
, both the new Fragment
and the target Fragment
must be hosted within the same FragmentManager
. The most common case where this would not happen is if you are using Activity.getSupportFragmentManager()
or Fragment.getFragmentManager()
alongside Fragment.getChildFragmentManager()
.
In my solution, replace
getChildFragmentManager()
with
Activity.getSupportFragmentManager() or Fragment.getFragmentManager()
that worked for me. Thank Mr.Ben P
To new users where the "getFragmentManager" only work for it but don't want use deprecated method, the method "getParentFragmentManager" work too.
