android - 获取 facebook 相册和封面照片

Question

在我的应用程序中，我允许用户从 Facebook 上传照片。所以首先我获取所有用户相册:

new Request(session, "/me/albums", null, HttpMethod.GET, new Request.Callback() {
            public void onCompleted(Response response) {
}
};

然后我使用适配器在 GridView 中显示每个相册，所以在 getView 方法中我调用 /{album-id}/picture ，但我不知道如何解析响应。我必须如何处理 Response 对象才能在 ImageView 中显示图像？有没有更好的方法来做到这一点？

我是这样申请的

                Bundle params = new Bundle();
                params.putString("type", "thumbnail");
                String albumid = albums.get(position);
                new Request(session, "/"+ albumid +"/picture",
                        params, HttpMethod.GET, 
                        new Request.Callback() {
                    public void onCompleted(Response response) {

                        ViewHolder holder = new ViewHolder();
                    }
                }
                        ).executeAsync();

这就是我得到的:

{Response: responseCode: 200, graphObject: GraphObject{graphObjectClass=GraphObject, state={"FACEBOOK_NON_JSON_RESULT":"����\u0000\u0010JFIF\u0000\u0001\u0002\u0000\u0000\u0001\u0000\u0001\u0000\u0000��\u0000\u0004*\u0000��\u0002\u001cICC_PROFILE\u0000\u0001\u0001\u0000\u0000\u0002"}}, error: null, isFromCache:false}

要获取 facebook 相册，请使用此

    Bundle params = new Bundle();
                //params.putString("fields", "photos.limit(10),name,count");
                params.putString("access_token", facebook.getAccessToken());
                params.putString("limit", "1000");
                //me = new JSONObject(facebook.request("me/albums",params ,"GET"));
                System.out.println("params are: "+params);

                if(facebook.getAccessToken()!= null)
                {
                    me = new JSONObject(facebook.request("me/albums",params ,"GET"));
                }

                fbAlbumList.clear();
                try {
                    //JSONObject jsonObject = new JSONObject(respons);
                    JSONArray jsonArray = me.getJSONArray("data");
                    for (int i = 0; i < jsonArray.length(); i++) {
                        FbAlbumBean bean = new FbAlbumBean();
                        bean.albumId = jsonArray.getJSONObject(i).getString("id");
                        bean.albumName = jsonArray.getJSONObject(i).getString("name");
                        if(i!=0)
                        {
                        bean.coverId = jsonArray.getJSONObject(i).getString("cover_photo");
                        bean.albumCount = jsonArray.getJSONObject(i).getInt("count")+"";
                        }
                        fbAlbumList.add(bean);
                    }

通过 albumId 获取照片

public void fetchPhotosFromAlbumId(final String album_id, Activity activity){

    //new FetchAsyncTask().execute(album_id);

    progressDialog1 = ProgressDialog.show(activity,"", "Please wait...");
    System.out.println("progress dialog: "+progressDialog1);

    new Thread(new Runnable() {
        @Override
        public void run() {
            Looper.prepare();

            JSONObject me;
            try {
                fbPhotosList.clear();
                String offset1 = String.valueOf(offset+100);
                Bundle params = new Bundle();
                params.putString("limit", "1000");
                params.putString("access_token", facebook.getAccessToken());

                //me = new JSONObject(facebook.request("me/albums",params ,"GET"));
                me = new JSONObject(facebook.request(album_id+"/photos",params ,"GET"));
                System.out.println(me);

                JSONArray jsonArray = me.getJSONArray("data");
                for (int i = 0; i < jsonArray.length(); i++) {
                    CameraRollBean bean = new CameraRollBean();
                    bean.filePath = jsonArray.getJSONObject(i).getString("source");
                    bean.showRight_IB = false;
                    fbPhotosList.add(bean); 
                }
                System.out.println("size of fb album: "+fbAlbumList.size());
                FbAlbumsScreen.fromFbScreen = true;
                Intent intent = new Intent(_activity, CameraRollScreen.class);
                intent.putExtra("album_id", album_id);
                _activity.startActivity(intent);


                if(progressDialog1!=null)
                    progressDialog1.cancel();
            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (JSONException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }catch (Exception e){
                e.printStackTrace();
            }
        }
    }).start();

    progressDialog1.show();
}
