MotionEvent object used to report movement (mouse, pen, finger, trackball) events. Motion events may hold either absolute or relative movements and other data, depending on the type of device. Motion events describe movements in terms of an action code and a set of axis values. The action code specifies the state change that occurred such as a pointer going down or up. The axis values describe the position and other movement properties.
