title: MapView - Disable dragging around, but allow zooming
body: <p>I have a ViewPager with 3 fragments inside, on the outer right I want to display a MapView - working fine so far. But I'd like to disable dragging it around, but still let the user zoom in / out - with a fixed center. If the user would be allowed to drag the map around, it messes with the viewpager scrolling abilities.
  Tried to disable clickable + focusable but - of course - no zooming anymore..</p>
  
  <p>Looked at other questions here at stackoverflow but none provided a working solution so far.. </p>
  
  <p>Thanks!</p>
