更新UI时，界面闪烁。

[JustinChiang123]

执行以下2句代码的时候，app界面会看见floatingActionMenu闪烁几次。
1、floatingActionMenu.removeButton(fab)；
2、floatingActionMenu.addButton(fab)；

希望在floatingActionMenu关闭的时候更新UI时，界面不闪烁。

When the UI is updated, the interface flashes.

When executing the following two lines of code, the app interface will see floatingActionMenu flashes several times.
1, floatingActionMenu.removeButton (fab);
2, floatingActionMenu.addButton (fab);

I hope that when the floatingActionMenu closed when the UI update, the interface does not flash.
