Using an answer at https://stackoverflow.com/a/31094315/2914140 I made it so.

View.OnTouchListener swipeListener = new View.OnTouchListener() {
    private float dx;

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                dx = v.getX() - event.getRawX();
                break;
            case MotionEvent.ACTION_MOVE:
                // You can limit x-coordinate.
                float x = Math.min(event.getRawX() + dx, 0);
                // x = Math.max(x, ((View) v.getParent()).getWidth() - v.getWidth()); // Scroll if layout is wider than screen.
                v.animate()
                        .x(x)
                        .setDuration(0)
                        .start();
                break;
            default:
                return false;
        }
        return true;
    }
};

In getView of your adapter write:

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    final ViewHolder viewHolder;
    if (convertView == null) {
        convertView = inflater.inflate(R.layout.item_layout, false);
        viewHolder = new ViewHolder(convertView);
        convertView.setTag(viewHolder);
    } else {
        viewHolder = (ViewHolder) convertView.getTag();
    }

    // Fill data.
    final Item item = items.get(position);
    viewHolder.caption.setText(item.getCaption());
    // Set onTouch listener.
    convertView.setOnTouchListener(swipeListener);
    return convertView;
}

I think the same can be achieved by using HorizontalScrollView inside item_layout.xml.
