i wanna notified when fragment reenters before shared element transition happens, can activities onactivityreenter method. there similar way can fragments?
while there's no onactivityreenter method in fragment, i've found myself doing calling public method on fragment activity.
define public method in fragment class:
public void onreenter(intent data) { // whatever data here } then call when onactivityreenter called in activity:
@override public void onactivityreenter(int resultcode, intent data) { super.onactivityreenter(resultcode, data); itemfragment fragment = (itemfragment) getsupportfragmentmanager().findfragmentbytag(item_tag); if (fragment != null) { fragment.onreenter(data); } }
