title: React Native Sticky Header using react-native-tab-view
body: <p>I'm trying to implement sticky header with tabbar in React Native. So when user scroll down, the header will collapse, and when scroll up, it will expand again. 
  But, I got a problem with <strong>blank space</strong>, if we move to an unscrollable tab. Also, I can't get the collapsed header back.   </p>
