機器人如何顯示我的Facebook好友，並邀請玩

 Session session = Session.getActiveSession(); 
     if (session == null || !session.isOpened()) { 
      return; 
     } 
     List<String> permissions = session.getPermissions(); 

     if (!permissions.contains("user_friends")) { 

      askForFriendsForPlayPermission(session); 

     } else { 
      loadFriendsFromFacebook(new FriendsLoadedCallback() { 

       @Override 
       public void afterFriendsLoaded() { 
        // startGame(); 
        close_button_value = 11; 
        img_close_button.setVisibility(View.VISIBLE); 
       } 

      }); 

     }

askForFriendsForPlayPermission（...）：這個功能可以拿朋友的權限，如果按是那麼它顯示FB好友列表，列表中的以下內容：

private void askForFriendsForPlayPermission(final Session session) { 
    // user has already said no once this session. 
    if (application.hasDeniedFriendPermission()) { 
    } else { 
     new AlertDialog.Builder(HomeActivity.this) 
       .setPositiveButton(R.string.dialog_yes, new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int id) { 
         // User hit OK. Request Facebook friends 
         // permission. 
          requestFriendsPermission(AUTH_FRIENDS_PLAY_ACTIVITY_CODE); 
        } 
       }).setNegativeButton(R.string.dialog_no, new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 
         // User hit cancel. Keep track of deny so 
         // that we 
         // only ask once per session 
         // and then just play the game. 
         application.setHasDeniedFriendPermission(true); 

        } 
       }).setTitle(R.string.with_friends_dialog_title).setMessage(R.string.with_friends_dialog_message) 
       .show(); 
    } 
}

採取user_friends權限 - 撥打：

private void requestFriendsPermission(int requestCode) { 
    // --//--Log.d("Permiision", "Requesting friends permissions."); 
    Session.NewPermissionsRequest newFriendsPermissionsRequest = new Session.NewPermissionsRequest(this, 
      "user_friends").setRequestCode(requestCode); 
    Session.getActiveSession().requestNewReadPermissions(newFriendsPermissionsRequest); 

}

負載Facebook上的朋友：

private void loadFriendsFromFacebook(final FriendsLoadedCallback callback) { 
    final Session session = Session.getActiveSession(); 
    RequestBatch requestBatch = new RequestBatch(); 
    Request invitableFriendsRequest = Request.newGraphPathRequest(session, "/me/invitable_friends", 
      new Request.Callback() { 

       @Override 
       public void onCompleted(Response response) { 

        FacebookRequestError error = response.getError(); 
        if (error != null) { 
         Log.e(CricoApplication.TAG, error.toString()); 
         // handleError(error, true); 
        } else if (session == Session.getActiveSession()) { 
         if (response != null) { 
          // Get the result 
          GraphObject graphObject = response.getGraphObject(); 
          JSONArray dataArray = (JSONArray) graphObject.getProperty("data"); 

          List<JSONObject> invitableFriends = new ArrayList<JSONObject>(); 
          if (dataArray.length() > 0) { 
           // Ensure the user has at least one friend 
           // ... 
           // fb_friends = new ArrayList<String>(); 
           list_fb_friends = new ArrayList<HashMap<String, String>>(); 
           for (int i = 0; i < dataArray.length(); i++) { 
            invitableFriends.add(dataArray.optJSONObject(i)); 
            try { 
             JSONObject json = dataArray.getJSONObject(i); 
             String str_id = json.getString(TAG_ID); 
             String str_first_name = json.getString(TAG_FIRST_NAME); 

             JSONObject picture_obj = json.getJSONObject(TAG_PICTURE); 
             JSONObject data_obj = picture_obj.getJSONObject(TAG_DATA); 
             // String str_is_silhouette = 
             // data_obj.getString(TAG_IS_SILHOUETTE); 
             String str_url = data_obj.getString(TAG_URL); 

    // put fb id and friends name in map and add to list view 
             map_fb_friends = new HashMap<String, String>(); 
             map_fb_friends.put("str_id", str_id); 
             map_fb_friends.put("str_first_name", str_first_name); 
             map_fb_friends.put("str_url", str_url); 
             list_fb_friends.add(map_fb_friends); 
             fb_friends.add(str_id); 

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


LazyAdapter_fb_friends adapter = new LazyAdapter_fb_friends(HomeActivity.this, 
             list_fb_friends); 
Your_list_view.setAdapter(adapter); 
          } 

          application.setInvitableFriends(invitableFriends); 
         } 
        } 
       } 

      }); 
    Bundle invitableParams = new Bundle(); 
    invitableParams.putString("fields", "id,first_name,picture"); 
    invitableFriendsRequest.setParameters(invitableParams); 
    requestBatch.add(invitableFriendsRequest); 

    // Get the user's list of friends. 
    // This only returns friends who have installed the game. 
    Request friendsRequest = Request.newMyFriendsRequest(session, new Request.GraphUserListCallback() { 

     @Override 
     public void onCompleted(List<GraphUser> users, Response response) { 
      FacebookRequestError error = response.getError(); 
      if (error != null) { 
       Log.e(CricoApplication.TAG, error.toString()); 
       // handleError(error, true); 
      } else if (session == Session.getActiveSession()) { 
       // Set the friends attribute 
       application.setFriends(users); 
       callback.afterFriendsLoaded(); 
      } 
     } 
    });

您可以使用facebook-id邀請特定的朋友。

希望this將幫助你。
如果你想顯示你所有的朋友，那麼你要合併兩個API

誰不使用你的應用程序，他們可以通過調用圖形API invitable_friends here得到的朋友是代碼的文檔。
（invitable_friends只能得到，如果你FBApp 分類爲遊戲）誰已經在使用你的應用程序，他們可以通過調用圖形API的朋友

這裏得到的，如果你想

友要檢索invitable_friends，那麼你必須login with permission。

然後在這裏發送邀請的最後一件事是documentation。
