android - Android滑动至打开侧边菜单如何工作？(How do android swipe-to-open side menus work?)

Question

How does the side menu in android work?

(android中的侧面菜单如何工作？)

I mean how does the app detect that a user is swiping from the edge of the device/screen?

(我的意思是，应用程序如何检测到用户正在从设备/屏幕的边缘滑动？)

• Is there an invisible handle of some sort on the edge that gets dragged while swiping from edge?

  (从边缘滑动时，边缘上是否存在某种隐形手柄？)

  If so, what is its width?

  (如果是这样，它的宽度是多少？)

• Does the app make the let padding into a trigger of some kind that detects the swipe within it?

  (该应用程序是否将让填充变成某种类型的触发器，以检测其中的滑动？)

I don't need the code to implement a menu just the underlying principle of swipe detection & execution...

(我不需要代码来实现菜单，而只需执行滑动检测和执行的基本原理...)
