title: Disable everything and place an ActivityIndicator in front of it in React Native
body: <p>I have a button which calls a fetch, but I can still press the button while the fetch is running. I want to disable this button (and all inputs if possible) and place an ActivityIndicator in front of it.</p>
  
  <p>Is there an option for this in the ActivityIndicator? <br />
  My current ActivityIndicator looks like this. It is only displayed, when I set <code>this.state.animating</code> to <code>true</code>.</p>
  
  <pre><code>&lt;ActivityIndicator
      animating={this.state.animating}
      style={{marginTop: 80}}
      size="large"
  /&gt;
  </code></pre>
  
  <p>I've found <a href="https://stackoverflow.com/a/44046858/7772870">this</a> answere, but it seems like the button won't get disabled as well.</p>
