连续显示XToast，the specified child already has a parent. You must call removeView() on the child's parent first.

Queue队列，show的时候，队列取出toast1对象ddView到ViewGroup，并没有及时把toast1移除队列，在hide的时候才在队列中移除，如果在hide之前用户再次触发显示操作，队列会再次拿出toast1对象addView到ViewGroup里，触发the specified child already has a parent. You must call removeView() on the child's parent first.
