集成Facebook后与Facebook登录SDK

-2

如何在我的应用程序中集成登录和Facebook？我已经整合了Facebook SDK，但我无法打开Facebook的登录活动。集成Facebook后与Facebook登录SDK

我试试这个，

// Your Facebook APP ID 
    private static String APP_ID = "MY_ID"; 

    @Override 
    protected void onCreate(Bundle 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 
        } 
       }); 

// 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 
      } 
     }); 

     return view; 
    } 
     loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() { 
      @Override 
      public void onSuccess(LoginResult loginResult) { 
       info.setText(
         "User ID: " 
           + loginResult.getAccessToken().getUserId() 
           + "\n" + 
           "Auth Token: " 
           + loginResult.getAccessToken().getToken() 
       ); 
      } 

      @Override 
      public void onCancel() { 
       info.setText("Login attempt canceled."); 
      } 

      @Override 
      public void onError(FacebookException e) { 
       info.setText("Login attempt failed."); 
      } 
     }); 
    }

其中Facebook的SDK实现这个代码是你想用集成？ – vaibhav

facebook sdk 4.6.0 –

您是否在您的清单中声明了facebook活动 – Jinu

下面是完整的代码来获取Facebook的个人资料的细节......我已经使用Facebook的SDK 4.4.0

public class MainActivity extends Activity { 

    LoginButton loginButton; 
    private CallbackManager callbackManager; 
    private ProgressDialog pDialog; 
    URL myurl; 
    String profilepic; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     FacebookSdk.sdkInitialize(MainActivity.this); 
     setContentView(R.layout.activity_main); 

     loginButton = (LoginButton) findViewById(R.id.login_button); 
     loginButton.setReadPermissions(Arrays 
       .asList("public_profile, email, user_birthday, user_friends")); 

     callbackManager = CallbackManager.Factory.create(); 
     loginButton.registerCallback(callbackManager, 
       new FacebookCallback<LoginResult>() { 
        @Override 
        public void onSuccess(LoginResult loginResult) { 
         new fblogin().execute(loginResult.getAccessToken()); 
        } 

        @Override 
        public void onCancel() { 

        } 

        @Override 
        public void onError(FacebookException e) { 

        } 
       }); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 

    public class fblogin extends AsyncTask<AccessToken, String, String> { 
     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 
      pDialog = new ProgressDialog(MainActivity.this); 
      pDialog.setMessage("Loading..."); 
      pDialog.setIndeterminate(false); 
      pDialog.setCancelable(false); 
      pDialog.show(); 
     } 

     protected String doInBackground(AccessToken... params) { 
      GraphRequest request = GraphRequest.newMeRequest(params[0], 
        new GraphRequest.GraphJSONObjectCallback() { 
         @Override 
         public void onCompleted(JSONObject object, 
           GraphResponse response) { 
          Log.v("MainActivity", response.toString()); 
          try { 
           String profile_pic = object.getString("id"); 
           try { 
            myurl = new URL(
              "https://graph.facebook.com/" 
                + profile_pic + "/picture"); 
           } catch (Exception e) { 
            e.printStackTrace(); 
           } 
           profilepic = myurl.toString(); 


           Log.v("Name", object.getString("first_name")); 
           Log.v("Email", object.getString("email")); 
           Log.v("Profile Pic Url", profilepic); 
           Log.v("Gender", object.getString("gender")); 

          } catch (JSONException jse) { 
           // session.logoutUser(); 
           Log.e("fb json exception", jse.toString()); 
          } 
         } 
        }); 
      Bundle parameters = new Bundle(); 
      parameters.putString("fields", "id,first_name,email,gender"); 
      request.setParameters(parameters); 
      GraphRequest.executeBatchAndWait(request); 
      return null; 
     } 

     protected void onPostExecute(String file_url) { 
      pDialog.dismiss(); 

     } 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int responseCode, 
      Intent intent) { 
     // TODO Auto-generated method stub 
     callbackManager.onActivityResult(requestCode, responseCode, intent); 
    } 
}

在清单文件中添加此

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

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

在Facebook上只需创建应用程序，并得到指纹
下载Facebook SDK，并将其导入到你的项目

MainActivity

import java.util.Arrays; 

import android.content.Intent; 
import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import android.util.Log; 
import android.widget.TextView; 

import com.example.facebookapp.R; 
import com.facebook.Session; 
import com.facebook.SessionState; 
import com.facebook.UiLifecycleHelper; 
import com.facebook.model.GraphUser; 
import com.facebook.widget.LoginButton; 
import com.facebook.widget.LoginButton.UserInfoChangedCallback; 

public class MainActivity extends FragmentActivity { 

    private LoginButton loginBtn; 
    private TextView username; 
    private UiLifecycleHelper uiHelper; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     uiHelper = new UiLifecycleHelper(this, statusCallback); 
     uiHelper.onCreate(savedInstanceState); 

     setContentView(R.layout.activity_main); 

     username = (TextView) findViewById(R.id.username); 
     loginBtn = (LoginButton) findViewById(R.id.fb_login_button); 
     loginBtn.setReadPermissions(Arrays.asList("email")); 
     loginBtn.setUserInfoChangedCallback(new UserInfoChangedCallback() { 
      @Override 
      public void onUserInfoFetched(GraphUser user) { 
       if (user != null) { 
        username.setText("You are currently logged in as " + user.getName()); 
       } else { 
        username.setText("You are not logged in."); 
       } 
      } 
     }); 
    } 

    private Session.StatusCallback statusCallback = new Session.StatusCallback() { 
     @Override 
     public void call(Session session, SessionState state, 
       Exception exception) { 
      if (state.isOpened()) { 
       Log.d("MainActivity", "Facebook session opened."); 
      } else if (state.isClosed()) { 
       Log.d("MainActivity", "Facebook session closed."); 
      } 
     } 
    }; 

    @Override 
    public void onResume() { 
     super.onResume(); 
     uiHelper.onResume(); 
    } 

    @Override 
    public void onPause() { 
     super.onPause(); 
     uiHelper.onPause(); 
    } 

    @Override 
    public void onDestroy() { 
     super.onDestroy(); 
     uiHelper.onDestroy(); 
    } 

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

    @Override 
    public void onSaveInstanceState(Bundle savedState) { 
     super.onSaveInstanceState(savedState); 
     uiHelper.onSaveInstanceState(savedState); 
    } 
}

activity_main.xml中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    xmlns:facebook="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 


    <com.facebook.widget.LoginButton 
     android:id="@+id/fb_login_button" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginTop="5dp" 
     facebook:confirm_logout="false" 
     facebook:fetch_user_info="true" /> 

    <TextView 
     android:id="@+id/username" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center" 
     android:layout_margin="10dp" 
     android:textSize="16sp" /> 

</LinearLayout>

在您的清单加这个

<activity android:name="com.facebook.LoginActivity" 
      android:theme="@android:style/Theme.Translucent.NoTitleBar" /> 
     <meta-data android:name="com.facebook.sdk.ApplicationId" 
      android:value="@string/APP_ID" />

我通过移除facebook sdk和只添加dependancies compile 'com.facebook.android:facebook-android-sdk:3.21.1'得到它，在我的Login_activity

private Session.StatusCallback statusCallback = new Session.StatusCallback() { 
     @Override 
     public void call(Session session, SessionState state, 
         Exception exception) { 
      if (state.isOpened()) { 
       buttonsEnabled(true); 
       //Log.d("FacebookSampleActivity", "Facebook session opened"); 
      } else if (state.isClosed()) { 
       buttonsEnabled(false); 
       //Log.d("FacebookSampleActivity", "Facebook session closed"); 
      } 
     } 
    }; 
{ 
if (!session.isClosed()) { 
       session.closeAndClearTokenInformation(); 
       //clear your preferences if saved 
} 
     } 
else 
{ 
session = new Session(context); 
      Session.setActiveSession(session); 
      session.closeAndClearTokenInformation(); 
      //clear your preferences if saved 
} 
}
