i getting multiple errors "button cannot resolved type" , "r cannot resolved variable" these mean?

`import android.os.bundle; import android.app.activity; import android.view.menu;

public class startscreen extends activity {

  edittext edittext1 = (edittext) findviewbyid(r.id.edittext1);     button btn = (button) findviewbyid(r.id.button);     btn.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {             // todo auto-generated method stub                  string answer = edittext1.gettext().tostring().trim();                 if (answer.equals("desired answer")) {                     intent = new intent(getapplicationcontext(),                             correctansweractivity.class);                     startactivity(i);                 } else {                     intent = new intent(getapplicationcontext(),                             wrongansweractivity.class);                     startactivity(i);                 }             }      }); 

`

1. get value of edittext

2. check desired answer

3. if true, redirect next activity

eg :

  if(edittext1.gettext().tostring().equalsignorecase("desiredanswer")   {                startactivity(new intent(this,nextactivity.class));   }   else   {                 toast.maketext(this,"wrong answer",2000).show();   }
