标签: java android facebook android-fragments facebook-login

我有一个FragmentActivity和另一个片段,它有一些文本和一个facebook登录按钮。

main.xml中

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

 <fragment
    android:id="@+id/initialFragment"
    android:name="com.tests.android.InitialFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

 <fragment
    android:id="@+id/loginFragment"
    android:name="com.tests.android.LoginFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
</LinearLayout>

初始片段

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true" >
...
        <com.facebook.widget.LoginButton
            android:id="@+id/loginButtonFacebook"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginBottom="110dp" />
...
</ScrollView>

我的java课程:

InitialActivity.java

public class InitialActivity extends FragmentActivity {

public static final int INITIAL = 0;

private static final int REAUTH_ACTIVITY_CODE = 100;

private Fragment[] fragments = new Fragment[FRAGMENT_COUNT];

private UserHelper userHelper = null;

private UiLifecycleHelper uiHelper;

    @Override
    public void call(Session session, SessionState state,
            Exception exception) {
        onSessionStateChange(session, state, exception);
    }

    return callback;
}


@Override

    super.onCreate(savedInstanceState);

    uiHelper = new UiLifecycleHelper(this, callback);

    userHelper = new UserHelper(getApplicationContext());

    setContentView(R.layout.main);

    FragmentManager fm = getSupportFragmentManager();
    //fm.addOnBackStackChangedListener(getListener());
    fragments[INITIAL] = fm.findFragmentById(R.id.initialFragment);
    fragments[LOGIN_APP] = fm.findFragmentById(R.id.loginFragment);
    fragments[SIGNIN_APP] = fm.findFragmentById(R.id.profileFragment);

    FragmentTransaction transaction = fm.beginTransaction();
    for (int i = 0; i < fragments.length; i++) {
        transaction.hide(fragments[i]);
    }
    transaction.commit();       
}

public void showFragment(int fragmentIndex, boolean addToBackStack) {

    transaction.commit();
}

@Override

    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REAUTH_ACTIVITY_CODE) {
        uiHelper.onActivityResult(requestCode, resultCode, data);
    } 


}

public void onSessionStateChange(Session session, SessionState state,
        Exception exception) {
    // Only make changes if the activity is visible
    if (isResumed) {
        FragmentManager manager = getSupportFragmentManager();

    }
}

private void makeMeRequest(final Session session) {

    // new callback to handle the response.
    Request request = Request.newMeRequest(session,

                // Handle errors, will do so later.
            }
        }
    });
    request.executeAsync();
} 

@Override

    super.onResumeFragments();
    if(ACTIVE_FRAGMENT == -1){
        Session session = Session.getActiveSession();       
        Boolean isLogged = userHelper.isLogged();       
        if ((session != null && session.isOpened()) || isLogged.equals(Boolean.TRUE)) {

        }
    } else {
        this.showFragment(ACTIVE_FRAGMENT, true);
    }       
}

InitialFragment.java

 public class InitialFragment extends Fragment  implements CustomFragmentOperations {

        ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.initial, 
            container, false);

    final InitialActivity mainActivity = ((InitialActivity)getActivity());
   LoginButton loginButtonFacebook = (LoginButton) view
            .findViewById(R.id.loginButtonFacebook);
   loginButtonFacebook.setFragment(this);

   loginButtonFacebook.setSessionStatusCallback(mainActivity.getCallback());


  /*loginButtonFacebook.setReadPermissions(Arrays.asList("user_likes",
            "user_status", "email", "basic_info"));*/

    Button buttonExit = (Button) view.findViewById(R.id.buttonExit);
    buttonExit.setOnClickListener(new View.OnClickListener() {
        @Override

            mainActivity.ACTIVE_FRAGMENT = InitialActivity.SIGNIN_MOMNT;
            mainActivity.showFragment(InitialActivity.SIGNIN_MOMNT, true);
        }
    });

    Button buttonLoginApp = (Button) view.findViewById(R.id.buttonLoginApp);
    buttonLoginApp.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            mainActivity.ACTIVE_FRAGMENT = InitialActivity.LOGIN_MOMNT;
            mainActivity.showFragment(InitialActivity.LOGIN_MOMNT, true);
        }
    });

    return view;
}


问题是方法makeMeARequest()永远不会被调用,因为Session总是打开...为什么不改变这一点打开&gt;开业?我可以登录facebook并授权我的应用,但会话永远不会改为打开。

是否遗漏了什么?

我已经修好了..只需要将所有Facebook代码移动到我的片段。
