这里解释一下，为什么不复用 WindowManager.LayoutParams 这个对象
因为如果复用了，不同 Activity 之间不能共用一个，第一个 Activity 调用显示方法可以显示出来，但是会导致后面的 Activity 都显示不出来
又或者说，非第一次调用显示方法的 Activity 都会把这个显示请求推送给之前第一个调用显示的 Activity 上面，如果第一个 Activity 已经销毁，还会报以下异常
android.view.WindowManager$BadTokenException:
Unable to add window -- token [email protected] is not valid; is your activity running?
