Android Firebase身份验证阻止布局膨胀？

我在Android应用程序上实现Firebase身份验证时遇到问题。 下面是AndroidStudio 2.2预览版3（工具->Firebase->身份验证->设置Firebase身份验证）中的说明

下面是

my onCreate（）

方法：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_register);

    mAuth = FirebaseAuth.getInstance();

    mAuthListener = new FirebaseAuth.AuthStateListener() {
        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
            FirebaseUser user = firebaseAuth.getCurrentUser();
            if (user != null) {
                // User is signed in
                Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid());

            } else {
                // User is signed out
                Log.d(TAG, "onAuthStateChanged:signed_out");
            }

        }
    };
    Log.d(TAG, mAuth.toString());

    mAuth.addAuthStateListener(mAuthListener);

    final EditText emailField = (EditText) findViewById(R.id.emailField);
    final EditText passwordField = (EditText) findViewById(R.id.passwordField);
    Button registerButton = (Button) findViewById(R.id.registerButton);

    registerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String email = emailField.getText().toString();
            String password = passwordField.getText().toString();

            mAuth.createUserWithEmailAndPassword(email, password)
                    .addOnCompleteListener(RegisterActivity.this, new OnCompleteListener<AuthResult>() {
                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task) {
                            Log.d(TAG, "createUserWithEmail:onComplete: " + task.isSuccessful());

                            if (!task.isSuccessful()) {
                                Toast.makeText(RegisterActivity.this, "Authentication failed.", Toast.LENGTH_SHORT).show();
                            }
                        }
                    }
            );
        }
    });


}
