Android中FaceBook第三方登入整合

標籤：

1、首先是要先下載 FaceBook SDK Android 版；

2、匯入FaceBookSDK 作為Library 引入到自己的項目中

3、在FaceBook 註冊一個 測試應用

4、配置AndroidManifest.xml：

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

在String 中添加： 

<string name="app_id">1548440642074664</string>

5、添加 Facebook 登入按鈕 ：

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

6、在activity中添加代碼：

public class MainActivity extends Activity {private static final String TAG = "MainActivity";private UiLifecycleHelper uiHelper;private Session.StatusCallback callback = new Session.StatusCallback() {@Overridepublic void call(Session session, SessionState state,Exception exception) {onSessionStateChange(session, state, exception);}};@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);uiHelper = new UiLifecycleHelper(MainActivity.this, callback);uiHelper.onCreate(savedInstanceState);setContentView(R.layout.activity_main);LoginButton authButton = (LoginButton) findViewById(R.id.login_button);authButton.setReadPermissions(Arrays.asList("email","user_likes", "user_status"));}private void onSessionStateChange(Session session, SessionState state,Exception exception) {if (state.isOpened()) {Log.i(TAG, "Logged in...");} else if (state.isClosed()) {Log.i(TAG, "Logged out...");}}@Overridepublic void onResume() {super.onResume();// For scenarios where the main activity is launched and user// session is not null, the session state change notification// may not be triggered. Trigger it if it's open/closed.Session session = Session.getActiveSession();if (session != null && (session.isOpened() || session.isClosed())) {onSessionStateChange(session, session.getState(), null);}uiHelper.onResume();}@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);uiHelper.onActivityResult(requestCode, resultCode, data);}@Overridepublic void onPause() {super.onPause();uiHelper.onPause();}@Overridepublic void onDestroy() {super.onDestroy();uiHelper.onDestroy();}@Overridepublic void onSaveInstanceState(Bundle outState) {super.onSaveInstanceState(outState);uiHelper.onSaveInstanceState(outState);}}

如果想得到使用者的基本資料：

private void getUserInfo() {  String fqlQuery = "SELECT uid,name,email FROM user WHERE uid = me()";          Bundle params = new Bundle();          params.putString("q", fqlQuery);          Request request = new Request(Session.getActiveSession(),              "/me",                                       params,                                       HttpMethod.GET,                               new Request.Callback(){                           public void onCompleted(Response response) {                      String str = response.toString();                  Log.i(TAG, str);                 }                            });           Request.executeBatchAsync(request);}
