            FacebookSdk.sdkInitialize(this.getApplicationContext());
            callbackManager = CallbackManager.Factory.create();

            setContentView(R.layout.main);

            tvfirst_name        = (TextView) findViewById(R.id.first_name);

            login_button        = (LoginButton) findViewById(R.id.login_button);

            login_button.setReadPermissions(Arrays.asList("public_profile","email"));
            login_button.registerCallback(callbackManager, new FacebookCallback<LoginResult>()
            {
                @Override

                                first_name  =   object.optString("first_name");
                                last_name   =   object.optString("last_name");

                                tvEmail.setText(email);
                                tvfirst_name.setText(first_name);

                                LoginManager.getInstance().logOut();
                            }
                            catch (JSONException e)
                            {

                            }
                        }
                    });

                    Bundle parameters = new Bundle();
                    parameters.putString("fields", "id,name,first_name,last_name,email");
                    graphRequest.setParameters(parameters);
                    graphRequest.executeAsync();
                }

                @Override
                public void onCancel()
                {

                }

                @Override
                public void onError(FacebookException exception)
                {

                }

Answer 2

你可以使用Facebook Android SDK。在这里，您已经在documentation中解释了如何为您的应用构建Facebook登录。

它说：

将Facebook登录添加到您的应用程序的最简单方法是从SDK添加LoginButton。这是Button的自定义视图实现。您可以在应用中使用此按钮来实施Facebook登录。

添加登录按钮

使用完整的类名com.facebook.widget.LoginButton将按钮添加到布局XML文件中：
<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" />
然后在UI中设置按钮，将其添加到片段中并更新您的活动以使用您的片段。

您可以自定义“登录”按钮的属性，并在onCreateView()方法中注册回调。

您可以自定义的属性包括LoginBehavior，DefaultAudience，ToolTipPopup.Style和LoginButton的权限。例如：
@Override
public View onCreateView(
        LayoutInflater inflater,
        ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.splash, container, false);

    loginButton = (LoginButton) view.findViewById(R.id.login_button);
    loginButton.setReadPermissions("user_friends");
    // If using in a fragment
    loginButton.setFragment(this);    
    // Other app specific specialization

    // Callback registration
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // App code
        }

        @Override
        public void onCancel() {
            // App code
        }

        @Override
        public void onError(FacebookException exception) {
            // App code
        }
    });    
}
如果在片段中使用LoginButton，则需要通过调用setFragment在按钮上设置片段。

然后，您需要调用FacebookSdk.initialize来初始化SDK，然后调用CallbackManager.Factory.create创建一个回调管理器来处理登录响应。以下是在片段中添加回调的示例：
public class MainActivity extends FragmentActivity {
    CallbackManager callbackManager;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        FacebookSdk.sdkInitialize(getApplicationContext());
        callbackManager = CallbackManager.Factory.create();
        LoginButton loginButton = (LoginButton) view.findViewById(R.id.usersettings_fragment_login_button);
        loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() { ... });
    }
最后你应该调用callbackManager.onActivityResult通过LoginManager将登录结果传递给callbackManager。

注册回拨

要响应登录结果，您需要使用LoginManager或LoginButton注册回调。如果您使用LoginButton注册回调，则无需在登录管理器上注册回调。

您将回调添加到您的活动或片段的onCreate()方法：
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(this.getApplicationContext());

    callbackManager = CallbackManager.Factory.create();

    LoginManager.getInstance().registerCallback(callbackManager,
            new FacebookCallback<LoginResult>() {
                @Override
                public void onSuccess(LoginResult loginResult) {
                    // App code
                }

                @Override
                public void onCancel() {
                     // App code
                }

                @Override
                public void onError(FacebookException exception) {
                     // App code   
                }
    });
}
如果登录成功，则LoginResult参数具有新的AccessToken，以及最近授予或拒绝的权限。

登录成功时不需要registerCallback，您可以选择使用下面描述的AccessTokenTracker类跟踪当前访问令牌更改。

然后在onActivityResult()中将登录结果转发给在callbackManager中创建的onCreate()：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);
}
您与FacebookSDK登录或共享集成的每个活动和片段都应该将onActivityResult转发到callbackManager。

Answer 3

我使用facebook sdk 4.10.0在我的Android应用程序中集成登录。我遵循的教程是：

Facebook login integration android studio.

您将能够从facebbok获取名字，姓氏，电子邮件，性别，脸书ID和出生日期。

Answer 4

首先转到https://developers.facebook.com/，登录并选择我的应用程序并创建一个应用程序。
正确遵循给定的指令。
提供packagename和packagename.ActivityName，选择使用App name然后保存它。
生成哈希密钥（下载OpenSSL）和（Java JDK）。 - 对于窗户！
将OpenSSL内容解压缩到C：\ OpenSSL
转到CMD提示符将当前路径设置为JDK的bin文件夹。
然后使用此命令：

keytool -exportcert -alias androiddebugkey -keystore“C：\ Users \ Shredder \ .android \ debug.keystore”| “C：\ OpenSSL \ bin \ openssl”sha1 -binary | “C：\ OpenSSL \ bin \ openssl”base64

确保你使用像UserAccountName等正确的路径.Mine是碎纸机。之后使用密码：123456。

将hashKey粘贴到必填字段。然后跟着......
如果需要，请使用以下代码。 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_sign__in); String fb_id =""; String fb_fName =""; String fb_lName =""; String fb_email =""; String EMAIL = "email"; CallbackManager callbackManager = CallbackManager.Factory.create(); final LoginButton loginButton = (LoginButton) findViewById(R.id.login_button); loginButton.setReadPermissions(Arrays.asList(EMAIL)); loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() { @Override public void onSuccess(LoginResult loginResult) { String userId = loginResult.getAccessToken().getUserId(); GraphRequest graphRequest = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() { @Override public void onCompleted(JSONObject object, GraphResponse response) { getUserFbUserInfo (object); } }); Bundle parameters = new Bundle(); parameters.putString("fields", "first_name,last_name,email,id"); graphRequest.setParameters(parameters); graphRequest.executeAsync(); Intent it = new Intent(getApplicationContext(), Home_Page.class); it.putExtra("fbLogin", true); startActivity(it); } @Override public void onCancel() { // App code } @Override public void onError(FacebookException exception) { // App code } }); } private void getUserFbUserInfo(JSONObject object) { try { fb_email = object.getString("email"); fb_fName = object.getString("first_name"); fb_lName = object.getString("last_name"); fb_id = object.getString("id"); } catch (JSONException e) { e.printStackTrace(); } } @Override protected void onActivityResult ( int requestCode, int resultCode, Intent data){ callbackManager.onActivityResult(requestCode, resultCode, data); super.onActivityResult(requestCode, resultCode, data); } }

检查这个简单的Facebook登录库：

https://github.com/sromku/android-simple-facebook

这是我上传的演示链接到简单的Facebook登录与自定义按钮：http://www.demoadda.com/demo/android/login-with-facebook_108

它是在android应用程序中实现facebook登录的最简单方法。

您可以添加如下按钮：

<TextView
            android:id="@+id/btnFb"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="5dp"
            android:background="@null"
            android:gravity="center"
            android:text="Login with Facebook"
            android:textColor="@color/white" />

在gradle文件中，您可以添加：

compile 'com.sromku:simple-fb:4.1.1'

请检查。
