title: How to centralize text in textinput
body: <p>One short question.<br>
  Is there a way to centralize text in react-native <code>Textinput</code>?</p>
  
  <p>Here is the markup in jsx:</p>
  
  <pre><code>&lt;TextInput style={styles.input} placeholder="Your Account" /&gt;
  </code></pre>
  
  <p>In styles.input, just try to add <code>textAlign:"center"</code>, it's not working.</p>
  
  <p>And same as add alignAlign to the markup as an attribute.
  Could anybody do me a favor? Thx.</p>
