android intent - Errors with taking photos and setting it in imageview with Fragments -

i cannot seem able take photo camera , set imageview. have tried many different ways either receive errors or image view wont display photo took. i'll post have coded @ moment

 @override public view oncreateview(layoutinflater inflater, viewgroup container,                          bundle savedinstancestate) {     view view = inflater.inflate(r.layout.fragment_snap, container, false);      imageview imageview = (imageview) view.findviewbyid(r.id.camera_display);     button camera_btn = (button) view.findviewbyid(r.id.camera_btn);       camera_btn.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view view) {             intent intent = new intent(mediastore.action_image_capture);              getactivity().startactivityforresult(intent, capture_image_activity_request_code);             }      });      return view; } 

then onactivityresult

   @override public void onactivityresult(int requestcode, int resultcode, intent data) {     if (requestcode == capture_image_activity_request_code && resultcode == getactivity().result_ok) {         bundle extras = data.getextras();         bitmap imagebitmap = (bitmap) extras.get("data");          imageview.setimagebitmap(imagebitmap);     } } 

edit getting error

here did:

public class mainactivity extends activity {
