How to implement swipe to delete with a Recyclerview using the support library. Functionality was added in version 22.2 of the support library.

build.gradle

compile 'com.android.support:recyclerview-v7:22.2.0'

RecyclerViewFragment.java

        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
        recyclerView.setAdapter(adapter);

        SimpleCallback simpleCallback = new SimpleCallback(0, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {
            @Override
            public boolean onMove(RecyclerView recyclerView, ViewHolder viewHolder, ViewHolder viewHolder1) {
                return false;
            }

            @Override
            public void onSwiped(ViewHolder viewHolder, int i) {
                int pos = viewHolder.getAdapterPosition();
                listener.onItemSwiped(items.get(pos)); // Tell the listener about the swipe so it can perform the delete.
            }
        };

        ItemTouchHelper itemTouchHelper = new ItemTouchHelper(simpleCallback);
        itemTouchHelper.attachToRecyclerView(recyclerView);
