Android:获取facebook好友列表

Question

我正在使用Facebook SDK在墙上发布消息.

现在我需要获取Facebook好友列表.任何人都可以帮我吗？

- 编辑 -

try {

  Facebook mFacebook = new Facebook(Constants.FB_APP_ID);
  AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(mFacebook);
  Bundle bundle = new Bundle();
  bundle.putString("fields", "birthday");
  mFacebook.request("me/friends", bundle);

} catch(Exception e){
    Log.e(Constants.LOGTAG, " " + CLASSTAG + " Exception = "+e.getMessage());
}

当我执行我的时候activity,我没有看到任何东西,但是LogCat有一个调试消息,如:

06-04 17:43:13.863: DEBUG/Facebook-Util(409): GET URL: https://graph.facebook.com/me/friends?format=json&fields=birthday

当我尝试直接从浏览器访问此URL时,我收到以下错误响应:

{
  error: {
  type: "OAuthException"
  message: "An active access token must be used to query information about the current user."
 }
}

你差不多到了一半.您已发送请求,但尚未定义任何内容以接收包含结果的响应.您可以扩展BaseRequestListener类并实现其onComplete方法来执行此操作.像这样的东西:

public class FriendListRequestListener extends BaseRequestListener {

    public void onComplete(final String response) {
        _error = null;

        try {
            JSONObject json = Util.parseJson(response);
            final JSONArray friends = json.getJSONArray("data");

            FacebookActivity.this.runOnUiThread(new Runnable() {
                public void run() {
                    // Do stuff here with your friends array, 
                    // which is an array of JSONObjects.
                }
            });

        } catch (JSONException e) {
            _error = "JSON Error in response";
        } catch (FacebookError e) {
            _error = "Facebook Error: " + e.getMessage();
        }

        if (_error != null)
        {
            FacebookActivity.this.runOnUiThread(new Runnable() {
                public void run() {
                    Toast.makeText(getApplicationContext(), "Error occurred:  " + 
                                    _error, Toast.LENGTH_LONG).show();
                }
            });
        }
    }
}

然后在您的请求中,您可以指定用于接收请求响应的请求侦听器,如下所示:

mFacebook.request("me/friends", bundle, new FriendListRequestListener());

使用FQL查询

String fqlQuery = "SELECT uid, name, pic_square FROM user WHERE uid IN " +
        "(SELECT uid2 FROM friend WHERE uid1 = me() LIMIT 25)";

Bundle params = new Bundle();
params.putString("q", fqlQuery);
Session session = Session.getActiveSession();

Request request = new Request(session,"/fql", params,HttpMethod.GET, new Request.Callback(){         
    public void onCompleted(Response response) {
        Log.i(TAG, "Result: " + response.toString());

        try{

            GraphObject graphObject = response.getGraphObject();

            JSONObject jsonObject = graphObject.getInnerJSONObject();
            Log.d("data", jsonObject.toString(0));

            JSONArray array = jsonObject.getJSONArray("data");

            for(int i=0;i<array.length();i++)
            {
                JSONObject friend = array.getJSONObject(i);

                Log.d("uid",friend.getString("uid"));
                Log.d("name", friend.getString("name"));
                Log.d("pic_square",friend.getString("pic_square"));             

            }

        }catch(JSONException e){
            e.printStackTrace();
        }


    }                  
}); 
Request.executeBatchAsync(request);
