制作自己的注销按钮并在登录后重定向

Question

I made so I can login to Facebook by pressing the loginbutton. Just write in my user-name and password and it will log me in.

After that I have been logged in, it will take me back to the same Activity and with a blue Logout button.

Im going to build a navigator-drawer or actionbar, and THERE I will make an own logout button that logs me out from Facebook. In other words, I dont want the blue logout button.

Also, where can I redirect to another Activity after logging in?

So to be clear:

1. After logging in to Facebook, there will be no blue LogOut button, it will instead be a button in actionbar that is says logout and that button will log me out (how to, and what to delete in the code?)

2. After that I have logged in, I will redirect to a new Activity (how to..?) Here is my code:

---

public class SocialLoginFragment extends Fragment {

private static final String TAG = "MainFragment";
private UiLifecycleHelper uiHelper;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.activity_social_login, container,
            false);
    LoginButton authButton = (LoginButton) view
            .findViewById(R.id.authButton);
    authButton.setFragment(this);
    authButton.setReadPermissions(Arrays.asList("name", "user_birthday",
            "friends_birthday"));

    return view;
}

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...");
    }
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    uiHelper = new UiLifecycleHelper(getActivity(), callback);
    uiHelper.onCreate(savedInstanceState);
}

private Session.StatusCallback callback = new Session.StatusCallback() {
    @Override
    public void call(Session session, SessionState state,
            Exception exception) {
        onSessionStateChange(session, state, exception);
    }
};

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

    Session session = Session.getActiveSession();
    if (session != null && (session.isOpened() || session.isClosed())) {
        onSessionStateChange(session, session.getState(), null);
    }

    uiHelper.onResume();
}

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

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

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

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

}

And here is the other code:

public class SocialLoginActivity extends FragmentActivity {

private SocialLoginFragment socialLoginFragment;

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

    if (savedInstanceState == null) {
        // Add the fragment on initial activity setup
        socialLoginFragment = new SocialLoginFragment();
        getSupportFragmentManager().beginTransaction()
                .add(android.R.id.content, socialLoginFragment).commit();
    } else {
        // Or set the fragment from restored state info
        socialLoginFragment = (SocialLoginFragment) getSupportFragmentManager()
                .findFragmentById(android.R.id.content);
    }
}

}

EDIT :

I don't now if my problem/question was good written, will try again.

1. My Login to Facebook button are in the middle of my Activity, and thats fine. After that I login with the button, the button will change to LogOut. The thing is that I will have an ActionBar or make my own button and put it in the Navigator-Drawer, so therefore, I dont need the blue LogOut button, I will delete it and put what LogOut button do in another button that I made.. (How do I delete the Logout button without delete the Login button, and how do I make a new button that will logout from Facebook)

2. After that I logged in, I will come back to the same Activity, what I want to do is to send me to a new Activity, not the same Activity, in that way, the LogOut button will be gone?

ANOTHER EDIT:

Answer 1

If I understand what you are trying to do, you don't need to delete the buttons, just hide them.

To hide or show buttons, do something like this:

findViewById (R.id.login_button).setVisibility (View.GONE); // hides button

or

button.setVisibility (View.VISIBLE);

Answer 2

When the state is changed and you verify if the session is opened, you can create an intent to call your activity.

if (state.isOpened()) {
    Log.i(TAG, "Logged in...");
    Intent intent = new Intent(getActivity(), NewActivityYouMade.class);
    startActivity(intent);
}
