How to use

Add these Gradle dependencies to your app's module:

dependencies {
    ...

    // already includes 'com.android.support:recyclerview-v7:23.1.1'
    compile 'com.github.brnunes:swipeablerecyclerview:1.0.2'

    // only necessary if you are using CardView
    compile 'com.android.support:cardview-v7:23.1.1'
}

The RecyclerView and CardView widgets are part of the v7 Support Libraries.

Instantiate a SwipeableRecyclerViewTouchListener passing as parameters the RecyclerView and a SwipeableRecyclerViewTouchListener.SwipeListener that will receive the callbacks.

Add the instantiated SwipeableRecyclerViewTouchListener as a RecyclerView.OnItemTouchListener.

SwipeableRecyclerViewTouchListener swipeTouchListener =
        new SwipeableRecyclerViewTouchListener(mRecyclerView,
                new SwipeableRecyclerViewTouchListener.SwipeListener() {
                    @Override
                    public boolean canSwipeLeft(int position) {
                        return true;
                    }

                    @Override
                    public boolean canSwipeRight(int position) {
                        return true;
                    }

                    @Override
                    public void onDismissedBySwipeLeft(RecyclerView recyclerView, int[] reverseSortedPositions) {
                        for (int position : reverseSortedPositions) {
                            mItems.remove(position);
                            mAdapter.notifyItemRemoved(position);
                        }
                        mAdapter.notifyDataSetChanged();
                    }

                    @Override
                    public void onDismissedBySwipeRight(RecyclerView recyclerView, int[] reverseSortedPositions) {
                        for (int position : reverseSortedPositions) {
                            mItems.remove(position);
                            mAdapter.notifyItemRemoved(position);
                        }
                        mAdapter.notifyDataSetChanged();
                    }
                });

mRecyclerView.addOnItemTouchListener(swipeTouchListener);
