Facebook SDK Android-無法正常工作

Question

我對純粹的業余愛好者編碼感到很討厭。 我對C和PHP / mySQL有一定的經驗，因此可以讀一些代碼，也許還可以掌握不熟悉的語言。 任何幫助將不勝感激！

我最近一直在嘗試Android。 在玩過ATMEL IC和AVR編程后，這確實讓人喘不過氣來……但是我發現它令人沮喪的多了100倍！

我有一個基本的登錄腳本和活動，該腳本和活動應允許通過loginmanager（）函數登錄Facebook會話（類？Acitvity？View？Fragment？我還是不知道。從C，id稱為函數...）。

該應用程序請求如圖所示的相關權限，但是經過兩天的嘗試來弄清楚為什么……在調用LoginManager（）函數之后，我似乎無法在OnComplete（）函數中發生任何事情……

為什么我似乎無法成功登錄？ 還是就此而言...甚至是“已取消”或“錯誤”登錄名？

                Bundle parameters = new Bundle();

                request.setParameters(parameters);

            }

            @Override

            }

            @Override
            public void onError(FacebookException error) {
                Log.e("dd", "facebook login failed error");
            }
        });         // Close Login manager





    }
}

這是布局XML：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.j3den.fibre.SplashScreen"
    android:id="@+id/login_button">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="InfoBox"
        android:id="@+id/textView"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        android:editable="true" />
</RelativeLayout>

這是日志中的響應：

Answer 1

您的logcat日志無用，沒有Facebook錯誤。 您可能在代碼中錯過了這一點：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);
}

請閱讀Facebook登錄教程 。
