Create a new MotionEvent, filling in all of the basic values that define the motion.

Usage

From source file:Main.java

public static MotionEvent hoverMotionEventAtPosition(View view, int action, int xPercent, int yPercent) {
    MotionEvent ev = motionEventAtPosition(view, action, xPercent, yPercent);

    MotionEvent.PointerProperties[] pointerProperties = new MotionEvent.PointerProperties[1];
    pointerProperties[0] = new MotionEvent.PointerProperties();

    MotionEvent.PointerCoords[] pointerCoords = new MotionEvent.PointerCoords[1];
    pointerCoords[0] = new MotionEvent.PointerCoords();
    pointerCoords[0].x = ev.getX();//from ww w  . ja  va2  s .  c  om
    pointerCoords[0].y = ev.getY();

    return MotionEvent.obtain(ev.getDownTime(), ev.getEventTime(), ev.getAction(), 1, pointerProperties,
            pointerCoords, ev.getMetaState(), 0, ev.getXPrecision(), ev.getYPrecision(), ev.getDeviceId(),
            ev.getEdgeFlags(), InputDevice.SOURCE_CLASS_POINTER, ev.getFlags());

     * are set from uptime. and then in the follow up events the uptime is used for event time and the stored downtime
