如何使用 Graph API for android 獲取 facebook 用戶的位置

Question

我可以使用以下代碼獲取姓名、電子郵件、性別和出生日期

loginButton.setReadPermissions(Arrays.asList("public_profile, email, user_birthday, user_friends,user_location")); //我還添加了user_location

    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // App code
            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject object,GraphResponse response) {

                            Log.v("LoginActivity", response.toString());
                        }
                    });

            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender,birthday,location");   //and location parameter
            request.setParameters(parameters);
            request.executeAsync();


        }

        @Override
        public void onCancel() {
            // App code
            Log.v("LoginActivity", "cancel");
        }

        @Override
        public void onError(FacebookException exception) {
            // App code
            Log.v("LoginActivity", exception.getCause().toString());
        }
    });

但它只返回以下值。

07-22 12:53:05.639: E/Fb data(6560): {"id":"989472891104","name":"Karan Mer","email":"karan_mer2012@yahoo.co.in","gender":"male"}

我怎么能得到那個？？？

如果沒有在 facebook 上提交應用程序進行審核，我們將無法獲取 facebook 用戶的位置。 但出於測試目的，您可以獲取 App Developer、Admin 或 Tester 的位置。

從這里下載源代碼（ 在 android 中使用 Graph API 獲取 facebook 用戶的位置）

添加此依賴項：

Answer 3

首先，您需要為此提供 user_location

然后在你的

public void onCompleted(JSONObject object,GraphResponse response){

    JSONObject jsonObj = response.getGraphObject().getInnerJSONObject();
    GraphUser user = GraphObject.Factory.create(jsonObj,GraphUser.class);
    if (user.getLocation() != null && getLocation().getProperty("name")!= null) {
        userObject.userCity = user.getLocation().getProperty("name").toString();
    }
}

這對我有用，希望這對你有用
