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

3、获取app签名的Key Hashes 值（两种方式）
3.1方法1：
1 package com.pegasus.map.presentation.utils; 2 import android.content.Context; 3 import android.content.pm.PackageInfo; 4 import android.content.pm.PackageManager; 5 import android.content.pm.Signature; 6 import android.util.Base64; 7 import android.widget.Toast; 8 import java.security.MessageDigest; 9 import java.security.NoSuchAlgorithmException; 10 11 /** 12 * Created by ${zyj} on 2016/3/29. 13 */ 14 public class KeyHash { 15 16 /** 17 * 注意运行的时候，app需要正式的签名 18 * @param context 19 * @param packageName app的包名 20 */ 21 public static void getKeyHash( Context context , String packageName ){ 22 try { 23 PackageInfo info = null; 24 info = context.getPackageManager().getPackageInfo( packageName , PackageManager.GET_SIGNATURES ); 25 for ( Signature signature : info.signatures ) { 26 MessageDigest messageDigest = null; 27 messageDigest = MessageDigest.getInstance("SHA"); 28 messageDigest.update(signature.toByteArray()); 29 String hs = Base64.encodeToString(messageDigest.digest(), Base64.DEFAULT) ; 30 Toast.makeText(context, "" + hs , Toast.LENGTH_SHORT).show(); 31 } 32 } catch (PackageManager.NameNotFoundException e) { 33 e.printStackTrace(); 34 } catch (NoSuchAlgorithmException e) { 35 e.printStackTrace(); 36 } 37 } 38 }
3.2 命令行的方式获取 Key hash 值
3.2.1 ：首选保证你的电脑上有 openSSl 的库文件
下载 http://gnuwin32.sourceforge.net/packages/openssl.htm
3.2.2 ：解压下载的文件
3.2.3：cmd 命令行模式定位到 openssl 的 bin目录下
3.2.4：执行命令
keytool -exportcert -alias yiba -keystore C:\work\Key.jks | openssl sha1 -binary | openssl base64
注意： 1、这里的 yiba 代表app签名的别名，也就是 alias
2、C:\work\Key.jks 代表签名的路径，需要换成你签名的路径
3.2.5 如果你的电脑上没有下载 openssl 那么你执行下面的代码会出现
4、设置应用的基本配置

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
1 package com.pegasus.map.presentation.ui.activity; 2 import android.content.Intent; 3 import android.os.Bundle; 4 import android.widget.Toast; 5 import com.facebook.CallbackManager; 6 import com.facebook.FacebookCallback; 7 import com.facebook.FacebookException; 8 import com.facebook.login.LoginResult; 9 import com.facebook.login.widget.LoginButton; 10 import com.pegasus.map.R; 11 import com.pegasus.map.presentation.ui.base.BaseActivity; 12 import butterknife.Bind; 13 import butterknife.ButterKnife; 14 15 16 /** 17 * Created by ${zyj} on 2016/3/24. 18 * 登录 19 */ 20 21 public class LoginLoginActivity extends BaseActivity { 22 23 @Bind(R.id.facebook_bt) 24 public LoginButton facebook_bt; 25 26 private CallbackManager callbackManager ; 27 28 @Override 29 protected void onCreate(Bundle savedInstanceState) { 30 super.onCreate(savedInstanceState); 31 setContentView(R.layout.activity_login); 32 33 ButterKnife.bind(this); 34 callbackManager = CallbackManager.Factory.create() ; 35 36 init(); 37 } 38 39 private void init() { 40 41 facebook_bt.registerCallback(callbackManager, new FacebookCallback<LoginResult>() { 42 @Override 43 public void onSuccess(LoginResult loginResult) { 44 Toast.makeText(LoginLoginActivity.this, "facebook登录成功了", Toast.LENGTH_SHORT).show(); 45 log("facebook登录成功了" + loginResult.getAccessToken());
//获取登录信息
getLoginInfo( loginResult.getAccessToken() ) ; 46 } 47 48 @Override 49 public void onCancel() { 50 Toast.makeText(LoginLoginActivity.this, "facebook登录取消了", Toast.LENGTH_SHORT).show(); 51 log("facebook登录取消了"); 52 } 53 54 @Override 55 public void onError(FacebookException error) { 56 Toast.makeText(LoginLoginActivity.this, "facebook登录失败了", Toast.LENGTH_SHORT).show(); 57 log("facebook登录失败了"); 58 } 59 }); 60 61 } 62 63 @Override 64 protected void onActivityResult(int requestCode, int resultCode, Intent data) { 65 super.onActivityResult(requestCode, resultCode, data); 66 67 //facebook回调 68 callbackManager.onActivityResult( requestCode , resultCode ,data ) ; 69 } 70 }
1 /** 2 * 获取登录信息 3 * @param accessToken 4 */ 5 public void getLoginInfo( AccessToken accessToken ){ 6 GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() { 7 @Override 8 public void onCompleted(JSONObject object, GraphResponse response) { 9 if (object != null) { 10 String id = object.optString( "id" ) ; //比如:1565455221565 11 String name = object.optString( "name" ) ; //比如：Zhang San 12 String gender = object.optString("gender") ; //性别：比如 male （男） female （女） 13 String emali = object.optString("email") ; //邮箱：比如：56236545@qq.com 14 15 //获取用户头像 16 JSONObject object_pic = object.optJSONObject( "picture" ) ; 17 JSONObject object_data = object_pic.optJSONObject( "data" ) ; 18 String photo = object_data.optString( "url" ) ; 19 20 //获取地域信息 21 String locale = object.optString( "locale" ) ; //zh_CN 代表中文简体 22 23 Toast.makeText( activity , "" + object.toString() , Toast.LENGTH_SHORT).show(); 24 } 25 } 26 }) ; 27 28 Bundle parameters = new Bundle(); 29 parameters.putString("fields", "id,name,link,gender,birthday,email,picture,locale,updated_time,timezone,age_range,first_name,last_name"); 30 request.setParameters(parameters); 31 request.executeAsync() ; 32 }
5.7 企业账号需要注意的事项，把发布按钮打开
6、对facebookSDk 进行二次封装
1 package com.pegasus.map.presentation.utils; 2 3 import android.app.Activity; 4 import android.content.DialogInterface; 5 import android.os.Bundle; 6 import android.support.v7.app.AlertDialog; 7 import android.widget.Toast; 8 9 import com.facebook.AccessToken; 10 import com.facebook.CallbackManager; 11 import com.facebook.FacebookCallback; 12 import com.facebook.FacebookException; 13 import com.facebook.GraphRequest; 14 import com.facebook.GraphResponse; 15 import com.facebook.Profile; 16 import com.facebook.login.LoginManager; 17 import com.facebook.login.LoginResult; 18 19 import org.json.JSONObject; 20 21 import java.util.Arrays; 22 import java.util.Collections; 23 import java.util.List; 24 25 /** 26 * Created by ${zyj} on 2016/3/30. 27 */ 28 public class FaceBookLogin { 29 30 private Activity activity ; 31 private CallbackManager callbackManager ; 32 private FacebookListener facebookListener ; 33 private List<String> permissions = Collections.<String>emptyList(); 34 private LoginManager loginManager; 35 36 public FaceBookLogin( Activity activity ){ 37 this.activity = activity ; 38 39 //初始化facebook登录服务 40 callbackManager = CallbackManager.Factory.create() ; 41 getLoginManager().registerCallback(callbackManager, new FacebookCallback<LoginResult>() { 42 @Override 43 public void onSuccess(LoginResult loginResult) { 44 // login success 45 AccessToken accessToken = loginResult.getAccessToken(); 46 getLoginInfo(accessToken); 47 } 48 49 @Override 50 public void onCancel() { 51 //取消登录 52 } 53 54 @Override 55 public void onError(FacebookException error) { 56 //登录出错 57 } 58 }); 59 60 permissions = Arrays 61 .asList("email", "user_likes", "user_status", "user_photos", "user_birthday", "public_profile", "user_friends") ; 62 } 63 64 /** 65 * 登录 66 */ 67 public void login(){ 68 getLoginManager().logInWithReadPermissions( 69 activity, permissions); 70 } 71 72 /** 73 * 退出 74 */ 75 public void logout(){ 76 String logout = activity.getResources().getString( 77 com.facebook.R.string.com_facebook_loginview_log_out_action); 78 String cancel = activity.getResources().getString( 79 com.facebook.R.string.com_facebook_loginview_cancel_action); 80 String message; 81 Profile profile = Profile.getCurrentProfile(); 82 if (profile != null && profile.getName() != null) { 83 message = String.format( 84 activity.getResources().getString( 85 com.facebook.R.string.com_facebook_loginview_logged_in_as), 86 profile.getName()); 87 } else { 88 message = activity.getResources().getString( 89 com.facebook.R.string.com_facebook_loginview_logged_in_using_facebook); 90 } 91 AlertDialog.Builder builder = new AlertDialog.Builder(activity); 92 builder.setMessage(message) 93 .setCancelable(true) 94 .setPositiveButton(logout, new DialogInterface.OnClickListener() { 95 public void onClick(DialogInterface dialog, int which) { 96 getLoginManager().logOut(); 97 } 98 }) 99 .setNegativeButton(cancel, null); 100 builder.create().show(); 101 } 102 103 /** 104 * 获取登录信息 105 * @param accessToken 106 */ 107 public void getLoginInfo( AccessToken accessToken ){ 108 GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() { 109 @Override 110 public void onCompleted(JSONObject object, GraphResponse response) { 111 if (object != null) { 112 String id = object.optString("id"); //比如:1565455221565 113 String name = object.optString("name"); //比如：Zhang San 114 String gender = object.optString("gender"); //性别：比如 male （男） female （女） 115 String emali = object.optString("email"); //邮箱：比如：56236545@qq.com 116 117 //获取用户头像 118 JSONObject object_pic = object.optJSONObject("picture"); 119 JSONObject object_data = object_pic.optJSONObject("data"); 120 String photo = object_data.optString("url"); 121 122 //获取地域信息 123 String locale = object.optString("locale"); //zh_CN 代表中文简体 124 125 Toast.makeText(activity, "" + object.toString(), Toast.LENGTH_SHORT).show(); 126 } 127 } 128 }) ; 129 130 Bundle parameters = new Bundle(); 131 parameters.putString("fields", "id,name,link,gender,birthday,email,picture,locale,updated_time,timezone,age_range,first_name,last_name"); 132 request.setParameters(parameters); 133 request.executeAsync() ; 134 } 135 136 /** 137 * 获取loginMananger 138 * @return 139 */ 140 private LoginManager getLoginManager() { 141 if (loginManager == null) { 142 loginManager = LoginManager.getInstance(); 143 } 144 return loginManager; 145 } 146 147 public CallbackManager getCallbackManager(){ 148 return callbackManager ; 149 } 150 151 /** 152 * 设置登录简体器 153 * @param facebookListener 154 */ 155 public void setFacebookListener( FacebookListener facebookListener ){ 156 this.facebookListener =facebookListener ; 157 } 158 159 public interface FacebookListener { 160 void facebookLoginSuccess(); 161 void facebookLoginFail() ; 162 } 163 164 165 }
在 activity 使用
1 //初始化Facebook登录服务 2 FaceBookLogin faceBookLogin = new FaceBookLogin( this ) ; 3 4 //登录 5 faceBookLogin.login(); 6 7 //退出 8 faceBookLogin.logout();
1 @Override 2 protected void onActivityResult(int requestCode, int resultCode, Intent data) { 3 super.onActivityResult(requestCode, resultCode, data); 4 5 //facebook回调 6 faceBookLogin.getCallbackManager().onActivityResult(requestCode, resultCode, data); 7 8 }
