title: Parallax-style item dragging Android (RecyclerView)
body: <p>I'm trying to add an effect with some items in a Recyclerview</p>
  
  <p>Basically, you can swipe an item in the recyclerview to the right, and the item will follow your touch until you've swiped, say %30 of the layout width, and the item will now follow your touch at half speed. With a layout underneath the Item view it can create a very nice parallax effect. you let go of the item and it smoothly slides back to where it began. The effect can be seen on Spotify (on iOS at least) where you can drag a track to queue it.</p>
  
  <p>I've looked everywhere but can't seem to find anything that allows me to change the swipe behavior, they all always track your touch exactly.</p>
  
  <p>More specifically itemTouchHelper didn't work. On a full swipe the item clamps to the right and the item gets on the pending removal list.</p>
  
  <p>DragViewHelper is a bit complicated and poorly documented. I couldn't find a way to get the x,y outside event.</p>
  
  <p>I tried implementing my own with a horizontalscrollview but couldn't get 2 views be the same size of the parent side by side (The idea is to listen to the scrollchange and translate main view by 1/2 after a certain scroll threshhold)</p>
  
  <p>I know my explaination sounds pretty abstract, but any implementation that can do the horizontal parallax would be appreciated.</p>
