android - Button.OnClickListener() gives error -


am new in android programming making app in when click button text gonna change... here code..

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      button himanshubutton = (button) findviewbyid(r.id.himanshubutton);     himanshubutton.setonclicklistener(             new button.onclicklistener() {                 public void onclick(view v){                     textview himanshutext = (textview)findviewbyid(r.id.himanshutext);                     himanshutext.settext("great himanshu rahi");

in button.onclicklistener gives me error red under line..

a better , neat way using method, ask implement setonclicklistener interface once himanshubutton.setonclicklistener(this);

protected void oncreate(bundle savedinstancestate) {     button himanshubutton = (button) findviewbyid(r.id.himanshubutton);     himanshubutton.setonclicklistener(this); }  @override public void onclick(){     textview himanshutext = (textview)findviewbyid(r.id.himanshutext);     himanshutext.settext("great himanshu rahi"); }
