Problema com a importação da Classe R

Olá. Fiz a importação da classe R (import br.com.rogeriopkf.ceep.R) no projeto mas acredito que não funcionou, pois além dessa texto ficar na cor cinza no console, continua com erro. Segue abaixo...

package br.com.rogeriopkf.ceep.ui.activity;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import br.com.rogeriopkf.ceep.R;

public class ListaNotasActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_lista_notas);
    }
}

Android resource linking failed
