How do I use the swipe gesture to remove cards within a recycleview?

How do I use the swipe gesture to remove cards from my recycle-view in the same way that it is done in Google-now etc. So far I've created the cardview application but it's removing cards via a swipe gesture which I'm having problems with. I haven't found a single tutorial or question answered on this website which could help.

Any help would be very much appreciated. My code is below.

MyActivity

public class MyActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_my);

        setContentView(R.layout.activity_my);
        RecyclerView recList = (RecyclerView) findViewById(R.id.cardList);
        recList.setHasFixedSize(true);
        LinearLayoutManager llm = new LinearLayoutManager(this);
        llm.setOrientation(LinearLayoutManager.VERTICAL);
        recList.setLayoutManager(llm);

        ContactAdapter ca = new ContactAdapter(createList(30));
        recList.setAdapter(ca);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.my, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }



    private List<ContactInfo> createList(int size) {

        List<ContactInfo> result = new ArrayList<ContactInfo>();
        for (int i=1; i <= size; i++) {
            ContactInfo ci = new ContactInfo();
            ci.name = ContactInfo.NAME_PREFIX + i;
            ci.surname = ContactInfo.SURNAME_PREFIX + i;
            ci.email = ContactInfo.EMAIL_PREFIX + i + "@test.com";

            result.add(ci);

        }

        return result;
    }
}

ContactInfo.java

public class ContactInfo {
    protected String name;
    protected String surname;
    protected String email;


    protected static final String NAME_PREFIX = "Name_";
    protected static final String SURNAME_PREFIX = "Surname_";
    protected static final String EMAIL_PREFIX = "email_";
}

ContactAdapter.java

public class ContactAdapter extends RecyclerView.Adapter<ContactAdapter.ContactViewHolder> {

    private List<ContactInfo> contactList;

    public ContactAdapter(List<ContactInfo> contactList) {
        this.contactList = contactList;
    }


    @Override
    public int getItemCount() {
        return contactList.size();
    }

    @Override
    public void onBindViewHolder(ContactViewHolder contactViewHolder, int i) {
        ContactInfo ci = contactList.get(i);
        contactViewHolder.vName.setText(ci.name);
        contactViewHolder.vSurname.setText(ci.surname);
        contactViewHolder.vEmail.setText(ci.email);
        contactViewHolder.vTitle.setText(ci.name + " " + ci.surname);
    }

    @Override
    public ContactViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
            View itemView = LayoutInflater.
                    from(viewGroup.getContext()).
                    inflate(R.layout.card_layout, viewGroup, false);

            return new ContactViewHolder(itemView);
    }

    public static class ContactViewHolder extends RecyclerView.ViewHolder {

        protected TextView vName;
        protected TextView vSurname;
        protected TextView vEmail;
        protected TextView vTitle;

        public ContactViewHolder(View v) {
            super(v);
            vName =  (TextView) v.findViewById(R.id.txtName);
            vSurname = (TextView)  v.findViewById(R.id.txtSurname);
            vEmail = (TextView)  v.findViewById(R.id.txtEmail);
            vTitle = (TextView) v.findViewById(R.id.title);
        }
    }
