When you touch a button, x, Y is relative to the upper-left point of the button (the control itself).
The Rawx,rawy is always relative to the screen position.
Know:
GETRAWX: The coordinates of the touch point relative to the screen
getx: The coordinates of the touch point relative to the button
gettop: The upper-left corner of the button is
getleft: The x-coordinate of the upper-left corner of the button relative to the parent view (linerlayout)

GetX () is the x-coordinate of the widget relative to its upper-left corner, and Getrawx () is the x-coordinate value relative to the upper-left corner of the screen (note: The upper-left corner of the screen is the upper-left corner of the phone screen, regardless of whether the activity has titlebar or full screen), GetY (), Getrawy () The same reason
