title: Cannot setTextColor if using ButterKnife?
body: <p>I have this code using ButterKnife:</p>
  
  <pre><code>public class MainActivity extends AppCompatActivity {
      @BindView(R.id.mainAct_OKBtnTv) TextView mTextView;
  
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
  
          mTextView.setTextColor(ContextCompat.getColor(this,R.color.black));
      }
  </code></pre>
  
  <p>This return the Null Exception.
  However, when I try the findViewById()</p>
  
  <pre><code>public class MainActivity extends AppCompatActivity {
      private TextView mTextView;
  
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
  
          mTextView = (TextView) findViewById(R.id.mainAct_OKBtnTv);
          mTextView.setTextColor(ContextCompat.getColor(this,R.color.black));
      }
  </code></pre>
  
  <p>The setTextColor method now is successful.
  I figured out the problem is I "try to find the text views before telling android which xml file to inflate". My question is: Is there anyway to use the ButterKnife with setTextColor?</p>
