android - onActivityResult inside a RecyclerView.Adapter not being used -

i have button inside adapter goes gallery:

    myadapter extends             recyclerview.adapter<recyclerview.viewholder> {     ...     onclic..{         intent intent = new intent(                                     intent.action_pick,                                     android.provider.mediastore.images.media.external_content_uri);                             intent.settype("image/*");                             ((activity) context).startactivityforresult(                                     intent.createchooser(intent, "select file"),                                     select_file);}     ....  @override     protected void onactivityresult(int requestcode, int resultcode, intent data) {         super.onactivityresult(requestcode, resultcode, data);         if (resultcode == result_ok) {         }     } ..     } 

what i'm trying update imageview image selected gallery, in order have use onactivityresult , compiler complaining method onactivityresult never used , cannot resolve method onactivityresult.

how can go ?

note on line using activity call startactivityforresult:

((activity) context).startactivityforresult(); 

onactivityresult(...) callback method , should in same activity used call startactivityforresult().

you getting compiler error because there no such method override named onactivityresult(...) recyclerview.adapter.

edit:

since asked how can here 1 option.

add following interface myadapter:

public interface onclickimagelistener{     void onclick(); } 

then have dialog implement interface. in onclick method do:

@override public void onclick() {     intent intent = new intent(intent.action_pick,             android.provider.mediastore.images.media.external_content_uri);     intent.settype("image/*");     startactivityforresult(            intent.createchooser(intent, "select file"), select_file); } 

you can add onactivityresult(...) method fragment , called.

to use when create myadapter pass fragment in argument constructor , reference onclickimagelistener click listener in adapter becomes:

imageclicklistener.onclick(); 

also note can add index onclick() method or whatever else need know item in adapter populate image once returned.
