Jo3rn:

Você precisa chamar findViewByIddepoissetContentView

LinearLayout guestlogin; // do not instantiate here

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        guestlogin = (LinearLayout) findViewById(R.id.guest);

        guestlogin.setOnClickListener (...)
