how find fragment includes particular view?

it easy find view knowing fragment , view id:

fragment.getview().findviewbyid(r.id.foo)

but want reversal: knowing view, find fragment.

so far best thought is:

i. set root view's tag fragment inflated it:

// in class extends fragment: @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { view rootview = inflater.inflate(r.layout.fragment_id, container, false); rootview.settag(this); // <======= !!! homecoming rootview; }

ii. then, it's relatively easy find root view among view's parents:

// in utility class: public static fragment gettagfragment(view view) { (view v = view; v != null; v = (v.getparent() instanceof view) ? (view)v.getparent() : null) { object tag = v.gettag(); if (tag != null && tag instanceof fragment) { homecoming (fragment)tag; } } homecoming null; }

iii. usage:

fragment f = gettagfragment(view);

ps can place onclick handler fragment, , works!
