title: React Native, TouchableOpacity wrapping floating button get nothing
body: <p>I'm creating a simple action button (floating button)</p>
  
  <p>This is working :</p>
  
  <pre><code>&lt;View style={{
      width: this.props.size,
      height: this.props.size,
      borderRadius: this.props.size / 2,
      backgroundColor: '#ee6e73',
      position: 'absolute',
      bottom: 10,
      right: 10,
      flexDirection:'row'
  }}&gt;
      &lt;Text&gt;
          +
      &lt;/Text&gt;
  &lt;/View&gt;
  </code></pre>
  
  <p>This is not :</p>
  
  <pre><code>&lt;TouchableOpacity
          onPress={()=&gt;{
          }} &gt;
      &lt;View style={{
          width: this.props.size,
          height: this.props.size,
          borderRadius: this.props.size / 2,
          backgroundColor: '#ee6e73',
          position: 'absolute',
          bottom: 10,
          right: 10,
          flexDirection:'row'
      }}&gt;
          &lt;Text&gt;
              +
          &lt;/Text&gt;
      &lt;/View&gt;
  &lt;/TouchableOpacity&gt;
  </code></pre>
  
  <p>Just wrap with TouchableOpacity then my button not show up without any errors.</p>
  
  <p>React 0.1.7, Android</p>
  
  <p>Then I try move styling from View to TouchableOpacity, It's work</p>
  
  <pre><code>&lt;TouchableOpacity
          onPress={()=&gt;{
          }} 
          style={{
              width: this.props.size,
              height: this.props.size,
              position: 'absolute',
              borderRadius: this.props.size / 2,
              backgroundColor: '#ee6e73',
              bottom: 10,
              right: 10,
          }}&gt;
      &lt;Text&gt;
          +
      &lt;/Text&gt;
  &lt;/TouchableOpacity&gt;
  </code></pre>

    <p>A wrapper for making views respond properly to touches.
    This is done without actually changing the view hierarchy, 
    and in general is easy to add to an app without weird side-effects.</p>

  <p>This mean I wrap my original view and it would work as I expected, But it's not.</p>
