i'm new don't know i'm doing wrong

        @override            public void onclick(view v) {         if         (edtnumber1.gettext().tostring().equals("")|| edtnumber2.gettext().tostring().equals(""))         {         toast msg = toast.maketext(getbasecontext(),"enter number please",toast.length_long);         msg.show();         }          else         {          = float.parsefloat(edtnumber1.gettext().tostring());          b = float.parsefloat(edtnumber2.gettext().tostring());          spinner = (spinner) findviewbyid(r.id.spinner1);          selecteditem = (string) spinner.getselecteditem();              if (selecteditem.trim().equals("100mm")) {                 total =  (int) (a * b * 10);             }              else if (selecteditem.trim().equals("215mm")) {                 total =  (int) (a * b * 20);             }              else if (selecteditem.trim().equals("325mm")) {                  total =  (int) (a * b * 30);             }                 intent intent = new intent(calculate.this,                         blamounts.class);                 intent.putextra("result",total);                 startactivity(intent);              }                     }               });`      }   }

second activity

protected void oncreate(bundle savedinstancestate) {     edittext answer = (edittext) findviewbyid(r.id.needed);        super.oncreate(savedinstancestate);     setcontentview(r.layout.materials_needed);     intent sender = getintent();             int result = sender.getextras().getint("result"); }

first should put edittext answer = (edittext) findviewbyid(r.id.needed); after setcontentview(r.layout.materials_needed);

second haven't set value answer edit text. try this:

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.materials_needed);     edittext answer = (edittext) findviewbyid(r.id.needed);     intent sender = getintent();             int result = sender.getextras().getint("result");     answer.settext(result+""); }
