android - Can't do intent on MapFragment class to another activity class -

i've searched , tried many ways on doing intent getactivity() / v.this / , app still stop working when clicking textview reservereply class simple imageview.

---- mapfragment.class ------

@override public void onclick(view v) { 

// put intent on front of codes test btw

    intent intent = new intent(mapfragment.this, reservereply.class);     startactivity(intent);     final string parkname = (string) v.gettag();     final string name = "testing test";     final string age = "21";        stringrequest request = new stringrequest(request.method.post, inserturl, new response.listener<string>() {          @override         public void onresponse(string response) {              system.out.println(response.tostring());         }      }, new response.errorlistener() {         @override         public void onerrorresponse(volleyerror error) {          }     }) {          @override         protected map<string, string> getparams() throws authfailureerror {             map<string,string> parameters  = new hashmap<string, string>();             parameters.put("firstname",parkname);             parameters.put("lastname",name);             parameters.put("age",age);              return parameters;           }      };      requestqueue.add(request);  } 

}

---- reservereply.class

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.reservation_reply);      imgreply  = (imageview)findviewbyid(r.id.imgreply);     imgreply.setimageresource(r.drawable.waiting);  } 

}

i tried implement view.onclicklistener in fragment not working. instead use setonclicklistener method directly , stuff... upvote if it...
