MotionEventwill sometimes return absolute X and Y coordinates relative to the view, and sometimes relative coordinates to the previous motion event.
MotionEvent有时会返回相对于视图的绝对 X 和 Y 坐标，有时会返回前一个运动事件的相对坐标。
getRawX()and getRawY()that is guaranteed to return absolute coordinates, relative to the device screen.
getRawX()并且getRawY()保证返回相对于设备屏幕的绝对坐标。
While getX()and getY(), should return you coordinates, relative to the View, that dispatched them.
而getX()and getY()，应该返回您相对于派遣它们的视图的坐标。
