FirebaseUI 登录方向

Question

我正在使用FirebaseUI进行登录。无论我尝试什么，我都无法使登录屏幕保持纵向模式。我在这里做错了什么？我怀疑这是清单中的东西。

有趣的是，初始屏幕保持纵向，之后直接进入横向模式。我找不到错误，请帮忙。

我的登录激活

公共类 SignInActivity 扩展了 AppCompatActivity {

public static final int RC_SIGN_IN = 1337;
private DatabaseReference mDatabase;
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthStateListener;
private FirebaseUser firebaseUser;
private AccessToken accessToken;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mDatabase = FirebaseDatabase.getInstance().getReference();
    mDatabase.keepSynced(true);
    mAuth = FirebaseAuth.getInstance();
    mAuthStateListener = new FirebaseAuth.AuthStateListener() {
        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth mAuth) {
            firebaseUser = mAuth.getCurrentUser();
            if (firebaseUser != null) {
                //signed in
                Intent intent = new Intent(SignInActivity.this, MainActivity.class);
                startActivity(intent);
            } else {
                //signed out
                startActivityForResult(
                        AuthUI.getInstance()

根据这篇Github帖子和这篇文章，在FirebaseUI上设置方向是不可能的。
