android - Setting data of EditText not working -

i trying set text of edittext via listview. once user chooses product listview, go activity holds edittext, , change text within edittext.

i relatively new android , java, excuse me being absolute nub.

list java:

        final listview listviewcpu = (listview) findviewbyid(r.id.listviewcpu);     listviewcpu.setchoicemode(listview.choice_mode_single);      string cpulist[] = {      "products go here", "products go here", "products go here", "products go here", "products go here", "products go here" };      arrayadapter<string> adapter = new arrayadapter<string>(this,             android.r.layout.simple_list_item_1, cpulist);      listviewcpu.setadapter(adapter);      listviewcpu.setonitemclicklistener(new onitemclicklistener() {          @override         public void onitemclick(adapterview<?> listview, view myview,                 int pos, long mylng) {             string cpu = (string) listview.getadapter().getitem(pos);              intent = new intent(getapplicationcontext(), listmenuactivity.class);             i.putextra(" ", cpu);             startactivity(i);          }     });  } } 

edittext java: getting error on "edittext4" defining "syntax error on token "edittext4", delete token"

        edittext cpu = (edittext) findviewbyid(r.id.autocompletetextview4);     cpu.setonclicklistener(new view.onclicklistener() {          @override         public void onclick(view v) {             // todo auto-generated method stub              intent cpulist = new intent(getapplicationcontext(),                     cpulist.class);             startactivityforresult(cpulist, 0);          }          intent = getintent();         string product = i.getstringextra(" ");         edittext cpu = ((edittext)findviewbyid(r.id.edittext4));         edittext4.settext(getintent(i).getstringextra(""));      }); 

you set way

    @override     public void onitemclick(adapterview<?> listview, view myview,             int pos, long mylng) {         string cpu = (string) listview.getadapter().getitem(pos);          intent = new intent(getapplicationcontext(), listmenuactivity.class);         i.putextra("key", cpu);         startactivity(i);      } }); 

get value that

    intent = getintent();     string product = i.getstringextra("key");     edittext cpu = ((edittext)findviewbyid(r.id.edittext4));     cpu.settext(product);
