获取头像的响应json :

{
    "data": {
    "is_silhouette": false,
    "url": "picture-url"
  },
}

我的解决方案代码:

   AccessToken accessToken = new AccessToken({access-token}
                        , {app-id}, {user-id}
                        , null, null, null, null, null);

                GraphRequest request = GraphRequest.newGraphPathRequest(
                        accessToken,
                        "/{user-id}/picture",
                        new GraphRequest.Callback() {
                            @Override
                            public void onCompleted(GraphResponse response) {
                                try {
                                    JSONObject responseJSONObject = response.getJSONObject();
                                    JSONObject data =  responseJSONObject.getJSONObject("data");

                                    Log.i("your tag", "picture url = "+data.getString("url"));
                                } catch (JSONException e) {
                                    e.printStackTrace();
                                }
                            }
                        });

                Bundle parameters = new Bundle();
                parameters.putString("redirect", "false");
                request.setParameters(parameters);
                request.executeAsync();
