title: Doesnt work my text input layout
body: <p>I'm a beginner in Android :( I'm using a text input layout but I cant catch any value of them! This is my code. For now I want to print the value "usuario" just to check if it has any value. I'm using Butterknife btw D:</p>
  
  <pre><code>public class IngresoFragment extends Fragment {
  
  @Bind(R.id.tilUsuario) TextInputLayout mTilUsuario;
  @Bind(R.id.tilPassword) TextInputLayout mTilPassword;
  @Bind(R.id.btnIngresar) Button btnIngresar;
  @Bind(R.id.tviLibre) TextView tviLibre;
  
  public IngresoFragment() {
      // Required empty public constructor
  }
  
  
  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
                           Bundle savedInstanceState) {
      View view = inflater.inflate(R.layout.fragment_ingreso, container, false);
      ButterKnife.bind(this,view);
      return view;
  }
  
  @Override
  public void onActivityCreated(Bundle savedInstanceState) {
      super.onActivityCreated(savedInstanceState);
      app();
  }
  
  void app(){
  
      mTilUsuario.setHint(getResources().getString(R.string.usuario));
      mTilPassword.setHint(getResources().getString(R.string.password));
      events();
  }
  
  void events(){
      btnIngresar.setOnClickListener(new View.OnClickListener() {
  
          String usuario = mTilUsuario.getEditText().getText().toString().trim();
          String password = mTilPassword.getEditText().getText().toString().trim();
  
          @Override
          public void onClick(View v) {
              Toast.makeText(getActivity(), usuario, Toast.LENGTH_LONG).show();
          }
      });
  }
  </code></pre>
