android ArrayList深复制（修改复制list不影响原list）

    public static <E> List<E> deepCopy(List<E> src) {
        try {
            ByteArrayOutputStream byteOut = new ByteArrayOutputStream();
            ObjectOutputStream out = new ObjectOutputStream(byteOut);
            out.writeObject(src);

            ByteArrayInputStream byteIn = new ByteArrayInputStream(byteOut.toByteArray());
            ObjectInputStream in = new ObjectInputStream(byteIn);
            @SuppressWarnings("unchecked")
            List<E> dest = (List<E>) in.readObject();
            return dest;
        } catch (Exception e) {
            e.printStackTrace();
            return new ArrayList<E>();
        }
    }
