title: onLayout with Image - React Native
body: <p>I have a problem with onLayout in Image:</p>
  
  <p>I have a function to display the dimension.</p>
  
  <pre><code>measureView(event) {
     console.log(event.nativeEvent.layout.width);
     console.log(event.nativeEvent.layout.height);
  }
  </code></pre>
  
  <p>This Works and shows me the dimension of the TouchableWithoutFeedback</p>
  
  <pre><code>&lt;TouchableWithoutFeedback
   style={styles.touchableWithoutFeedback}
   onLayout={(event) =&gt; this.measureView(event)}&gt;
       &lt;Image style={styles.image} 
       source={require("./../assets/images/photo_1.jpg")}/&gt;
  &lt;/TouchableWithoutFeedback&gt;
  </code></pre>
  
  <p>But With the onLayout in the Image, i got nothing, just undefined.</p>
  
  <pre><code>&lt;TouchableWithoutFeedback
   style={styles.touchableWithoutFeedback}&gt;
       &lt;Image style={styles.image} 
       source={require("./../assets/images/photo_1.jpg")}
       onLayout={(event) =&gt; this.measureView(event)}/&gt;
  &lt;/TouchableWithoutFeedback&gt;
  </code></pre>
  
  <p>Do you have an Idea why?</p>
  
  <p>Thanks!</p>
