Question

我的启动活动中的Facebook登录按钮正在关闭启动活动而不进行下一个活动。通过logcat的外观，甚至没有调用onSuccess方法。无论如何要让它去下一个活动？

public class SplashActivity extends Activity {

    private Intent intent;
    private Handler mHandler;
    private Runnable mNextRunnable;
    private final long SPLASH_TIME = 3000;
    private VideoView videoHolder;
    private LoginButton loginButton;
    private CallbackManager callbackManager;
    private AccessTokenTracker accessTokenTracker;
    private ImageView iv;
    private static final String TAG = SplashActivity.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        FacebookSdk.sdkInitialize(getApplicationContext());
        setContentView(R.layout.activity_splash);

//        try {
//            PackageInfo info = getPackageManager().getPackageInfo(
//                    "info.nexrave.nexrave",
//                    PackageManager.GET_SIGNATURES);
//            for (Signature signature : info.signatures) {
//                MessageDigest md = MessageDigest.getInstance("SHA");
//                md.update(signature.toByteArray());
//                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
//            }
//        } catch (Exception e) {
//
//        }

        Log.d(TAG, "Video about to be called");
        //Video settings
        videoHolder = (VideoView) findViewById(R.id.videoView);
        Uri video = Uri.parse("android.resource://" + getPackageName() + "/"
                + R.raw.video_footage);
        videoHolder.setVideoURI(video);
        videoHolder.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {
                mp.setLooping(true);
            }
        });
        videoHolder.start();

        //Facebook settings
        iv = (ImageView) findViewById(R.id.iv_splash_logo);
        loginButton = (LoginButton) findViewById(R.id.login_button);
        // Callback registration
        callbackManager = CallbackManager.Factory.create();
        loginButton.setReadPermissions("public_profile", "email", "user_friends");
        Log.d(TAG, "UpdateWithToken Called: registering callback");
        loginButton.registerCallback(callbackManager, mCallBack);
//        AppEventsLogger.activateApp(this);
        Log.d(TAG, "UpdateWithToken About To Be Called");
//        accessTokenTracker = new AccessTokenTracker() {
//            @Override
//            protected void onCurrentAccessTokenChanged(AccessToken oldAccessToken, AccessToken newAccessToken) {
//                updateWithToken(newAccessToken);
//            }
//        };
        updateWithToken(AccessToken.getCurrentAccessToken());
    }

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


    @Override
    protected void onPause() {
        super.onPause();
        finish();
    }

    private void makeVisible() {
        iv.setVisibility(View.VISIBLE);
        iv.bringToFront();
        loginButton.setVisibility(View.VISIBLE);
        loginButton.bringToFront();
    }

    private void updateWithToken(AccessToken currentAccessToken) {
        Log.d(TAG, "UpdateWithToken Called");
        if (currentAccessToken != null) {
            new Handler().postDelayed(new Runnable() {

                @Override
                public void run() {
                    Log.d(TAG, "UpdateWithToken Called: User logged in");
                    Intent i = new Intent(SplashActivity.this, FeedActivity.class);
                    startActivity(i);
                }

        } else {
            new Handler().postDelayed(new Runnable() {

            // App code
            Log.d(TAG, "UpdateWithToken Called: Done");
            //Placeholder: Need to check firebase to see if already registered
            intent = new Intent(SplashActivity.this, EnterPhoneNumber.class);
            startActivity(intent);

        }

        @Override

Answer 1

我发现了一些事情......

声明

Profile profile;
private ProfileTracker mProfileTracker;

在你的onCreate（）

中

    FacebookSdk.sdkInitialize(getApplicationContext());
    callbackManager = CallbackManager.Factory.create();
    updateWithToken(AccessToken.getCurrentAccessToken());
    accessTokenTracker = new AccessTokenTracker() {
        @Override
        protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {
            updateWithToken(newToken);
        }
    };
    accessTokenTracker.startTracking();

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

你的updateWithToken（）方法中的

private void updateWithToken(AccessToken currentAccessToken) {

    if (currentAccessToken != null) {
        //User logged In--do your stuff
    } else {
        //user not logged in
    }
}

同样在你的回调方法中

private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {

    @Override
    public void onSuccess(LoginResult loginResult) {
        try {
            if (Profile.getCurrentProfile() == null) {
                mProfileTracker = new ProfileTracker() {
                    @Override
                    protected void onCurrentProfileChanged(Profile profile_old, Profile profile_new) {
                        // profile2 is the new profile
                        profile = profile_new;
                        Log.v("facebook - profile", profile_new.getFirstName());
                        mProfileTracker.stopTracking();
                    }
                };
                mProfileTracker.startTracking();
            } else {
                profile = Profile.getCurrentProfile();
                Log.v("facebook - profile", profile.getFirstName());
            }

            Intent  intent = new Intent(getApplicationContext(), EnterPhoneNumber.class);
            startActivity(intent);
        } catch (Exception e) {
            Log.d("ERROR", e.toString());
        }
    }

    @Override
    public void onCancel() {

    }

    @Override
    public void onError(FacebookException e) {
        Log.d("FACEBOOK ERRROR", e.toString());
    }
};

同时在开发人员面板中正确添加Key Hash

在清单上添加：

<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/APP_ID" />

同样在你的布局中：

<com.facebook.login.widget.LoginButton xmlns:fb="http://schemas.android.com/apk/res-auto"
                android:id="@+id/login_button"
                android:layout_width="match_parent"
                android:layout_height="50dp"
                android:layout_centerHorizontal="true"
                android:layout_marginBottom="10dp"
                android:layout_marginLeft="@dimen/activity_left_margin"
                android:layout_marginRight="@dimen/activity_right_margin"
                android:background="@drawable/custom_facebook"
                android:drawableLeft="@drawable/fb"
                android:drawablePadding="15dp"
                android:gravity="center"
                android:padding="10dp"
                android:singleLine="true"
                android:text="Login with Facebook"
                android:textColor="@color/color_white"
                android:textSize="18sp"
                android:visibility="visible" />
