我想打一个应用程序，可以在当前显示的是什么，上方的屏幕上创建通知。

I want to make an app that can create notification on the screen on top of anything that is currently being displayed.

像这的应用程序（称为聊天头绘制的元素） 还是喜欢去短信弹出

Something Like This app (drawn elements called as Chat head) or like the Go SMS message popup

如果有可能绘制动态，包括触摸事件等它甚至会更好。

It would be even better if it is possible to draw it dynamically including touch events etc.

什么是传统的或标准的方式来做到这一点。

What is the conventional or standard way to do this

例：  如可点击或拖动无论你是否在主屏幕或应用程序的抽屉或其他应用程序

Example: Like an Icon that can be clicked or dragged no matter whether you are on homescreen or app drawer or other apps

编辑：

真诚的道歉我应该更早加入这些图片

Sincere apologies I should have added these pictures earlier

讲究靠近屏幕边缘的圆形图标，你可以在任何应用程序的任何地方将它们拖到

Pay attention to the circular icons near the edges of the screen You can drag them anywhere in any app

看到该图片链接
