Android 应用程序集成FaceBook 登录及二次封装

1、首先在Facebook 开发者平台注册一个账号

        https://developers.facebook.com/

      开发者后台  https://developers.facebook.com/apps

2、创建账号并且获得 APP ID

       图三

      

      图四

        

     图五

      

 3、获取app签名的Key Hashes 值（两种方式） 

       获取方式：https://blog.csdn.net/zhaoyanjun6/article/details/105344657                                    

 4、设置应用的基本配置

      图三

       

         

 5、App开始集成 FacebookSDk

        5.1 在项目的 build.gradle 添加

              compile 'com.facebook.android:facebook-android-sdk:4.10.1'

            查看最新的版本 ： http://search.maven.org/#search%7Cga%7C1%7Ccom.facebook.android

       5.2 在应用的 Application 里面初始化SDK

            //facebook登录初始化

      FacebookSdk.sdkInitialize( getApplicationContext() );

       5.3 在value文件夹下 strings.xml 中

              <!-- facebook 登录 key-->

      <string name="facebook_app_id">1001702146573854</string>

       5.4 在 AndroidManifest.xml 中          

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

<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"
    >
</activity>  

     

       5.5 在布局文件中定义登录按钮

 <com.facebook.login.widget.LoginButton
            android:id="@+id/facebook_bt"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="facebook login"
            >
 </com.facebook.login.widget.LoginButton>

　　 

       5.6 在代码中实现

    companion object {

        /**
         * 是否处在登陆状态
         */

Activity 使用示范

package com.enjoy.literaturemodule.account

import android.app.Activity
import android.content.Intent
import android.os.Bundle
import com.enjoy.literaturemodule.R
import com.enjoy.literaturemodule.account.login.facebook.FacebookLoginUtil
import kotlinx.android.synthetic.main.activity_login.*

/**
 * 登陆
 */
class LoginActivity : Activity() {

    private var faceBookUtil: FacebookLoginUtil? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_login)
        faceBookUtil = FacebookLoginUtil(this)

        facebook_login?.setOnClickListener {
            faceBookUtil?.login()
        }
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        //facebook 登陆
        //facebook回调
        faceBookUtil?.getCallbackManager()?.onActivityResult(requestCode, resultCode, data)
        super.onActivityResult(requestCode, resultCode, data)
    }
}
