title: when setText on editText TextWatcher.onTextChanged not called
body: <p>Whenever <code>EditText</code> string is changed, <code>onTextChanged</code> is called.</p>
  
  <p>Now when I start a new <code>Activity</code> and send data through <code>Bundle</code>, <code>onTextChanged</code> is not called. </p>
  
  <pre><code>if( getIntent().getExtras() != null) {
      Bundle b = getIntent().getExtras();
      int value = -1;
  
      if(b != null)
          value = b.getInt("key");
      edit1.setText("Mywords:");
  }
  </code></pre>
  
  <p>How can I call it ?</p>
