利用java线程显示所有图片，给给个图片添加线程;

 public void update(final String photoid, final ImageView imageView)      //下载照片
    {
        new Thread(new Runnable() {
            @Override
            public void run() {
                Bitmap b = null;
                OSSCredentialProvider credentialProvider = new OSSPlainTextAKSKCredentialProvider(ACCESS_ID, ACCESS_KEY);
                ClientConfiguration conf = new ClientConfiguration();
                conf.setConnectionTimeout(15 * 1000); // 连接超时，默认15秒
                conf.setSocketTimeout(15 * 1000); // socket超时，默认15秒
                conf.setMaxConcurrentRequest(8); // 最大并发请求数，默认5个
                conf.setMaxErrorRetry(2); // 失败后最大重试次数，默认2次
                // oss为全局变量，OSS_ENDPOINT是一个OSS区域地址
                oss = new OSSClient(getContext(), OSS_ENDPOINT, credentialProvider, conf);
                //构造下载文件请求
                //objectKey等同于objectName，表示从OSS下载文件时需要指定包含文件后缀在内的完整路径，例如abc/efg/123.jpg
                    GetObjectRequest get = new GetObjectRequest("sean1246", photoid);
                    //设置下载进度回调
                    get.setProgressListener(new OSSProgressCallback<GetObjectRequest>() {
