我已经查看了其他类似帖子以及那里纠正的问题，我没有得到任何问题......请帮忙

这是LogIn.java文件：

package com.example.francydarkcool.maps;

import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.telecom.Call;

import com.facebook.CallbackManager;
import com.facebook.FacebookSdk;
import com.facebook.appevents.AppEventsLogger;
import com.google.android.gms.appindexing.Action;
import com.google.android.gms.appindexing.AppIndex;
import com.google.android.gms.appindexing.Thing;
import com.google.android.gms.common.api.GoogleApiClient;

public class LogIn extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_log_in);
        FacebookSdk.sdkInitialize(getApplicationContext());
        AppEventsLogger.activateApp(this);
        System.out.println("here");
    }


    /**
     * ATTENTION: This was auto-generated to implement the App Indexing API.
     * See https://g.co/AppIndexing/AndroidStudio for more information.
     */
    public Action getIndexApiAction() {
        Thing object = new Thing.Builder()
                .setName("LogIn Page") // TODO: Define a title for the content shown.
                // TODO: Make sure this auto-generated URL is correct.
                .setUrl(Uri.parse("http://[ENTER-YOUR-URL-HERE]"))
                .build();
        return new Action.Builder(Action.TYPE_VIEW)
                .setObject(object)
                .setActionStatus(Action.STATUS_TYPE_COMPLETED)
                .build();
    }

    @Override
    public void onStart() {
        super.onStart();
    }

    @Override
    public void onStop() {
        super.onStop();
    }
}

这是activity_log_in.xml文件：

<?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:id="@+id/activity_log_in"
    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.example.francydarkcool.maps.LogIn">

    <com.facebook.login.widget.LoginButton
        android:id="@+id/login_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="30dp"
        android:layout_marginBottom="30dp" />

    <TextView
        android:text="Bine ati venit!"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/textView"
        android:textSize="32dp"
        android:textStyle="normal|bold|italic"
        android:textColor="@color/com_facebook_button_background_color_pressed"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="129dp" />

</RelativeLayout>

我已经添加了这个：

<activity android:name="com.facebook.FacebookActivity"
        android:configChanges=
            "keyboard|keyboardHidden|screenLayout|screenSize|orientation"
        android:theme="@android:style/Theme.Translucent.NoTitleBar"
        android:label="@string/app_name" />

在AndroidManifest.xml中，还有：

<meta-data
        android:name="com.facebook.sdk.ApplicationId" android:value="@string/xxxxx"/>

另外，在strings.xml中我添加了：

<string name="facebook_app_id">xxxx</string>

在您的错误消息中说明

Caused by: The SDK has not been initialized. Make sure to call FacebookSdk.sdkInitialize() first.

您的布局中有一个com.facebook.login.widget.LoginButton按钮，您尝试在调用FacebookSdk.sdkInitialize()方法之前将该布局设置为内容视图。交换这些陈述的顺序。

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_log_in);
    AppEventsLogger.activateApp(this);
    System.out.println("here");
}
