title: React Native Soft Keyboard Issue
body: <p>I have TextInput at the bottom of the screen. When TextInput is focused then keyboard appears and due to this all the flex view gets shrink to the available screen. I want to achieve that page layout should not change and input should be visible to user.</p>
  
  <pre><code>  &lt;View style={MainView}&gt;
          &lt;View style={subMain1}&gt;
              &lt;View style={{flex:1,backgroundColor:'#add264'}}&gt;&lt;/View&gt;
              &lt;View style={{flex:1,backgroundColor:'#b7d778'}}&gt;&lt;/View&gt;
              &lt;View style={{flex:1,backgroundColor:'#c2dd8b'}}&gt;&lt;/View&gt;
          &lt;/View&gt;
          &lt;View style={subMain2}&gt;
              &lt;View style={{flex:1,backgroundColor:'#cce39f'}}&gt;&lt;/View&gt;
              &lt;View style={{flex:1,backgroundColor:'#d6e9b3'}}&gt;&lt;/View&gt;
              &lt;View style={{flex:1,backgroundColor:'#69ee9a'}}&gt;
                  &lt;TextInput placeholder="input field"/&gt;
              &lt;/View&gt;
  
          &lt;/View&gt;
      &lt;/View&gt;
  </code></pre>
  
  <p>const Styles = {</p>
  
  <pre><code>MainView:{
      flex:1,
      backgroundColor:'green'
  },
  subMain1:{
      flex:1,
      backgroundColor:'blue'
  },
  subMain2:{
      flex:1,
      backgroundColor:'orange'
