编辑 - 当我调试代码时发现onSessionStatusCVhange方法经常以相同的状态打开并且每次打开新活动时被调用。 我给出异常的代码是 -

@Override
        protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.connect_fb_fragment);
    mContext = this;
    uiHelper = new UiLifecycleHelper(this, callback);
    uiHelper.onCreate(savedInstanceState);
    authButton = (LoginButton) findViewById(R.id.authButton);
    authButton.setReadPermissions(Arrays.asList("basic_info","email"));
    authButton.setBackgroundResource(R.drawable.register_with_facebook);
    authButton.setCompoundDrawablesWithIntrinsicBounds(0, 0, 0,0);
    authButton.setText("");
}
