title: How to touch and hold to select text in React Native
body: <p>I'm new to Android and trying to implement a rich editor using Text component of React Native. 
  However when I touch the text and hold for a moment, the text was not highlighted and the top bar with selection actions was not shown like what behaves in a webview or other applications.
  What am I missing or do I need to implement this feature by myself? If so could you point a direction?</p>
