Answer 2

I've just done this. This is how it looks like:

I don't have any CardView but you can have any layout (so you can add the support lib CardView or whatever you like).

This is how I did it. I used this library. Since the library has minSdkVersion 15 and we have 14, I copy-pasted the following classes directly from GitHub: OnItemClickListener, RecyclerViewAdapter, SwipeableItemClickListener, SwipeToDismissTouchListener and ViewAdapter (this are the only ones you need if you use a RecyclerView).

Because the lib has not been updated yet, you'll need to add the following method into SwipeableItemClickListener:

@Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}

Your list item layout should have the following structure:

<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="@dimen/list_item_article_height"
    >

    <!-- This is the layout you see always -->    
    <include
        layout="@layout/list_item_article"
        tools:visibility="gone"
        />

    <!-- This is the layout shown after swiping. Must have visibility="gone" -->
    <LinearLayout
        android:visibility="gone"
        tools:visibility="visible"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal"
        >    
        <TextView
            android:id="@+id/swipe_cancel"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_weight="2"
            android:text="@string/swipe_cancel"
            android:gravity="center"
            />    
        <TextView
            android:id="@+id/swipe_delete"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:text="@string/swipe_delete"
            android:gravity="center"
            android:background="#f00"
            android:textColor="#fff"
            />    
    </LinearLayout>    
</FrameLayout>

Then simply add this code to your Activity/Fragment after creating the RecyclerView and setting it's adapter:

final SwipeToDismissTouchListener<RecyclerViewAdapter> touchListener =
        new SwipeToDismissTouchListener<>(
                new RecyclerViewAdapter(mRecyclerView),
                new SwipeToDismissTouchListener.DismissCallbacks<RecyclerViewAdapter>() {
                    @Override
                    public boolean canDismiss(int position) {
                        return true;
                    }
                    @Override
                    public void onDismiss(RecyclerViewAdapter recyclerView, int position) {
                        // remove item at position and notify adapter
                    }
                }
        );
mRecyclerView.setOnTouchListener(touchListener);
mRecyclerView.addOnScrollListener((RecyclerView.OnScrollListener) touchListener.makeScrollListener());
mRecyclerView.addOnItemTouchListener(new SwipeableItemClickListener(
        getActivity(),
        new OnItemClickListener() {
            @Override
            public void onItemClick(View view, int position) {
                if (view.getId() == R.id.swipe_delete) {
                    touchListener.processPendingDismisses();
                } else {
                    touchListener.undoPendingDismiss();
                }
            }
        }
));

If you want to have only add and delete button you can use RecyclerView but with RecyclerView.Adapter not CardViewAdapter. Here is an example:

public class MyActivity extends Activity {
    private RecyclerView mRecyclerView;
    private RecyclerView.Adapter mAdapter;
    private RecyclerView.LayoutManager mLayoutManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_activity);
        mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);

        // use this setting to improve performance if you know that changes
        // in content do not change the layout size of the RecyclerView
        mRecyclerView.setHasFixedSize(true);

        // use a linear layout manager
        mLayoutManager = new LinearLayoutManager(this);
        mRecyclerView.setLayoutManager(mLayoutManager);

        // specify an adapter (see also next example)
        mAdapter = new MyAdapter(myDataset);
        mRecyclerView.setAdapter(mAdapter);
    }
    ...
}

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private String[] mDataset;

    // Provide a reference to the views for each data item
    // Complex data items may need more than one view per item, and
    // you provide access to all the views for a data item in a view holder
    public static class ViewHolder extends RecyclerView.ViewHolder {
        // each data item is just a string in this case
        public TextView mTextView;
        public ViewHolder(TextView v) {
            super(v);
            mTextView = v;
        }
    }

    // Provide a suitable constructor (depends on the kind of dataset)
    public MyAdapter(String[] myDataset) {
        mDataset = myDataset;
    }

    // Create new views (invoked by the layout manager)
    @Override
    public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                                   int viewType) {
        // create a new view
        View v = LayoutInflater.from(parent.getContext())
                               .inflate(R.layout.my_text_view, parent, false);
        // set the view's size, margins, paddings and layout parameters
        ...
        ViewHolder vh = new ViewHolder(v);
        return vh;
    }

    // Replace the contents of a view (invoked by the layout manager)
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        // - get element from your dataset at this position
        // - replace the contents of the view with that element
        holder.mTextView.setText(mDataset[position]);

    }

    // Return the size of your dataset (invoked by the layout manager)
    @Override
    public int getItemCount() {
        return mDataset.length;
    }
}
