title: react native view height not changing
body: <p>I'm very new to react native, maybe there is something that I'm missing here but I cannot find it.</p>
  
  <pre><code>  &lt;View style={{ width: width, height: height }}&gt;
      &lt;View style={styles.btns}&gt;
        &lt;TouchableHighlight
          style={styles.closeBtn}
          onPress={this.lets}
        &gt;
          &lt;Text&gt;✖&lt;/Text&gt;
        &lt;/TouchableHighlight&gt;
        &lt;TouchableHighlight
          style={styles.saveBtn}
          onPress={this.lets}
        &gt;
          &lt;Text&gt;Save&lt;/Text&gt;
        &lt;/TouchableHighlight&gt;
      &lt;/View&gt;
      &lt;FloatingInput placeholder='Task Title' /&gt;
      &lt;FloatingInput placeholder='Task Urgency' /&gt;
      &lt;FloatingInput placeholder='Task Importance' /&gt;
      &lt;FloatingInput placeholder='Task Due' /&gt;
      &lt;FloatingInput placeholder='Task Detail' /&gt;
    &lt;/View&gt;
  </code></pre>
  
  <p> and  have 111px height,
  and I set height styles to them, nothing happens.</p>
  
  <p>How can I fix this?</p>
