For this challenge, you will add swipe-to-dismiss functionality to enhance CriminalIntent’s RecyclerView user experience. Implementing swipe to dismiss will allow a user to delete a crime with a single swipe to the right.
To get swipe to dismiss set up with CrimeFragment’s RecyclerView, wire up an ItemTouchHelper (developer.android.com/reference/android/support/v7/widget/helper/ItemTouchHelper.xhtml). ItemTouchHelper provides a swipe-to-dismiss implementation and is included with the RecyclerView support library.
