如果照片不存在，则返回的InputStream为空。在尝试解码图像之前，您应该检查photo_stream是否为null。

try {
        photo_stream = ContactsContract.Contacts
                .openContactPhotoInputStream(getActivity()
                        .getContentResolver(), contactPhotoUri);
        if(photo_stream != null) {
        buf_stream = new BufferedInputStream(photo_stream);
        cPhoto = BitmapFactory.decodeStream(buf_stream);
    }
    } catch (Exception e) {
        e.printStackTrace();
        }
